Updated version to an RC1 release

Android Studio's Shell Script plugin cannot find cmd.exe when specified
as just "cmd.exe" - it doesn't search the system PATH. This caused
"Interpreter not found" errors when trying to run Build, Deploy, or Test
configurations on Windows.

Changed all Windows run configurations to use the full path:
C:\Windows\System32\cmd.exe

This fixes 5 run configurations:
- Build (Windows)
- Deploy (auto) (Windows)
- Deploy (USB) (Windows)
- Deploy (WiFi) (Windows)
- Test (Windows)

Unix configurations already used full paths (/bin/bash) so they were
unaffected.

Tested on Windows 11 with Android Studio - configurations now work
correctly without manual editing.

Fixes issue where users couldn't run any Android Studio configurations
on Windows without manually editing the interpreter path.

+## ⭐ What's New in v1.1.0
+
+### Professional Templates - The Game Changer!
+
+**Start with working, tested code instead of empty files!**
+
+```bash
+# Create with our professional testing showcase
+weevil new my-robot --template testing
+
+cd my-robot
+./gradlew test    # 45 tests pass in < 2 seconds ✓
+```
+
+**You get:**
+- ✅ 3 complete, working subsystems
+- ✅ Full hardware abstraction layer
+- ✅ 45 passing tests demonstrating best practices  
+- ✅ Professional documentation (6 files)
+- ✅ Real patterns used in competition
+
+**Why this matters:** Most FTC teams start with empty projects and learn by trial-and-error on hardware. Now you can learn from professional code, run tests instantly on your PC, and modify working examples for your robot.
+
+This is the kind of code students would write if they had years of experience. Now they can START with it.

 ### How It Works
 
 1. **Project Generation**
-   - Creates standalone Java project structure
+   - Creates standalone Java project
-   - Generates Gradle build files that reference FTC SDK
+   - Optionally overlays template (basic/testing)
+   - Generates build files referencing FTC SDK
    - Sets up deployment scripts
+   - Creates Android Studio integration
 
 2. **Build Process**
-   - Runs `deployToSDK` Gradle task
+   - Copies code to FTC SDK's TeamCode
-   - Copies your code to FTC SDK's `TeamCode` directory
+   - Builds APK using SDK
-   - Builds APK using SDK's Android configuration
+   - Leaves project directory clean
-   - Leaves your project directory clean
 
 3. **Deployment**
-   - Finds built APK in SDK
+   - Finds APK in SDK
-   - Connects to Control Hub (USB or WiFi)
+   - Connects to Control Hub (USB/WiFi)
-   - Installs APK using `adb`
+   - Installs using `adb`
 
 ### Why This Approach?
 
 **Separation of Concerns:**
 - Your code: `my-robot/src/`
-- Build infrastructure: `my-robot/*.gradle.kts`
+- Build infrastructure: `*.gradle.kts`
-- FTC SDK: System-level installation
+- FTC SDK: System installation
+- Templates: Starting points
 
 **Benefits:**
-- Test code without SDK complications
+- Test without SDK complications
-- Multiple projects per SDK installation
+- Multiple projects per SDK
-- SDK updates don't break your projects
+- SDK updates don't break projects
-- Proper version control (no massive SDK in repo)
+- Proper version control
-- Industry-standard project structure
+- Industry-standard structure
+- Learn from professional examples

 ```
 
 ### "adb: command not found"
-
-Install Android platform-tools:
-
-**Linux:**
 ```bash
-sudo apt install android-tools-adb
+weevil setup  # Installs Android SDK with adb
 ```
 
-**macOS:**
-```bash
-brew install android-platform-tools
-```
-
-**Windows:**
-Download Android SDK Platform Tools from Google.
-
 ### "Build failed"
-
 ```bash
-# Clean and rebuild
-cd my-robot
 ./gradlew clean
 ./build.sh
-
+weevil doctor
-# Check SDK path
-weevil config .
 ```
 
 ### "Deploy failed - No devices"
+**USB:** `./deploy.sh --usb`  
+**WiFi:** `./deploy.sh -i 192.168.43.1`

+# Weevil Template & Package System - Specification
+
+**Version:** 1.1  
+**Date:** February 2, 2026  
+**Status:** Template system ✅ COMPLETE | Package system 📋 Planned for v1.2.0
+
+---
+
+## Executive Summary
+
+This document specifies two complementary features for Weevil:
+
+1. **Template System (v1.1.0)** - ✅ **IMPLEMENTED** - Project scaffolding with professional code templates
+2. **`weevil add` Package System (v1.2.0)** - 📋 **PLANNED** - Component package management
+
+Together, these enable teams to start with professional code and extend projects with community-shared components.
+
+---
+
+## Part 1: Template System ✅ IMPLEMENTED in v1.1.0
+
+### Status: COMPLETE
+
+The template system has been fully implemented and shipped in v1.1.0.
+
+### Implementation Summary
+
+**Command Syntax:**
+```bash
+weevil new <project-name> [--template <name>] [--list-templates]
+```
+
+**Delivered Templates:**
+
+1. **`basic`** (default) - Minimal FTC project
+   - 8 files, ~50 lines of code
+   - Clean starting point
+   - Example OpMode placeholder
+
+2. **`testing`** - Professional showcase
+   - 28 files, ~2,500 lines of code
+   - 45 comprehensive tests (< 2 sec runtime)
+   - 3 complete subsystems
+   - Hardware abstraction layer
+   - Full documentation
+
+**Key Features Delivered:**
+- ✅ Template extraction and overlay system
+- ✅ Variable substitution (`{{PROJECT_NAME}}`, etc.)
+- ✅ Template validation with helpful errors
+- ✅ `--list-templates` command
+- ✅ Templates embedded in binary (no external files)
+- ✅ Complete test coverage (62 tests passing)
+
+### Template Variable Substitution
+
+Implemented variables:
+
+| Variable | Example Value |
+|----------|---------------|
+| `{{PROJECT_NAME}}` | `my-robot` |
+| `{{PACKAGE_NAME}}` | `myrobot` |
+| `{{CREATION_DATE}}` | `2026-02-02T10:30:00Z` |
+| `{{WEEVIL_VERSION}}` | `1.1.0` |
+| `{{TEMPLATE_NAME}}` | `testing` |
+
+### Testing Template Contents
+
+**Subsystems** (3):
+- `MotorCycler.java` - State machine for motor cycling
+- `WallApproach.java` - Sensor-based navigation
+- `TurnController.java` - Gyro-based turning
+
+**Hardware Layer** (12 files):
+- 3 interfaces (MotorController, DistanceSensor, GyroSensor)
+- 3 FTC implementations
+- 3 mock implementations
+- 3 additional interfaces
+
+**Tests** (45 tests):
+- Unit tests for each subsystem
+- Integration tests
+- All passing in < 2 seconds
+
+**Documentation** (6 files):
+- DESIGN_AND_TEST_PLAN.md (29 KB)
+- TESTING_GUIDE.md (13 KB)
+- TESTING_SHOWCASE.md (9 KB)
+- ARCHITECTURE.md (6 KB)
+- SOLUTION.md (3 KB)
+- QUICKSTART.md (5 KB)
+
+### Usage Examples
+
+```bash
+# Create with default template
+weevil new my-robot
+
+# Create with testing template
+weevil new my-robot --template testing
+
+# List available templates
+weevil new --list-templates
+
+# Output from list:
+# Available templates:
+#
+#   basic (default)
+#     Minimal FTC project structure
+#     Perfect for: Teams starting from scratch
+#     Files: ~10 | Code: ~50 lines
+#
+#   testing
+#     Professional testing showcase with examples
+#     Perfect for: Learning best practices
+#     Files: ~30 | Code: ~2,500 lines | Tests: 45
+#     Includes:
+#       • 3 complete subsystems
+#       • Hardware abstraction layer with mocks
+#       • 45 passing tests (< 2 seconds)
+#       • Comprehensive documentation
+```
+
+### Implementation Architecture
+
+**Storage:** Templates embedded in binary using `include_dir!` macro
+
+**Directory Structure:**
+```
+weevil/
+├── templates/
+│   ├── basic/
+│   │   ├── .gitignore
+│   │   ├── README.md.template
+│   │   ├── settings.gradle
+│   │   └── src/... (.gitkeep files)
+│   └── testing/
+│       ├── .gitignore
+│       ├── README.md.template
+│       ├── DESIGN_AND_TEST_PLAN.md
+│       ├── ... (6 doc files)
+│       └── src/
+│           ├── main/java/robot/
+│           │   ├── hardware/... (6 files)
+│           │   ├── subsystems/... (3 files)
+│           │   └── opmodes/...
+│           └── test/java/robot/
+│               ├── hardware/... (3 files)
+│               └── subsystems/... (4 files)
+```
+
+**Key Implementation Details:**
+- Templates complement ProjectBuilder (don't replace it)
+- ProjectBuilder creates infrastructure (.weevil.toml, build.gradle.kts, etc.)
+- Templates overlay content (source code, docs)
+- Files ending in `.template` get variable substitution
+- Regular files copied as-is
+
+### Success Metrics (Achieved)
+
+- ✅ 62 tests passing (zero warnings)
+- ✅ Testing template has 45 passing tests
+- ✅ Clean separation: ProjectBuilder vs Templates
+- ✅ Cross-platform compatibility (Windows, Linux, macOS)
+- ✅ No template fragmentation (templates don't include build files)
+- ✅ Professional code quality in testing template
+- ✅ Comprehensive documentation
+
+### Lessons Learned
+
+1. **Don't fight ProjectBuilder** - Templates should complement, not replace infrastructure
+2. **Embed in binary** - No external file dependencies
+3. **Variable substitution** - Essential for project-specific values
+4. **Test thoroughly** - Template extraction, variable substitution, file handling all need tests
+5. **Documentation matters** - The testing template's value is in its docs as much as code
+

+
+Grid-based robot localization with sensor fusion and fault tolerance.
+
+**Created:** {{CREATION_DATE}}
+**Weevil:** {{WEEVIL_VERSION}}
+**Template:** localization
+
+## What's Included
+
+- **Grid System** - 12x12 field grid (12" cells)
+- **Sensor Fusion** - Combine encoders, IMU, vision
+- **Fault Tolerance** - Graceful sensor failure handling
+- **3 Tests** - All passing

+```
+
+## Architecture
+
+Field divided into 144 cells (12x12 grid):
+- Cell (0,0) = Red backstage
+- Cell (11,11) = Blue backstage  
+- Cell (6,6) = Center
+
+Sensor fusion priority:
+1. Vision (AprilTags) - ±2" accuracy
+2. IMU + Odometry - ±4" accuracy
+3. Odometry only - ±12" accuracy
+
+## Files

+# Robot Localization Guide
+
+## What is Localization?
+
+Answering: "Where is my robot on the field?"
+
+## The Grid System
+
+12ft x 12ft field → 12x12 grid of 12" cells
+
+```
+Cell (0,0) = Red backstage
+Cell (11,11) = Blue backstage
+Cell (6,6) = Center
+```
+
+## Sensor Fusion
+
+Combine three sensors:
+
+1. **Odometry (Encoders)** - Track wheel rotation
+   - Accuracy: ±1" per foot (cumulative drift)
+   - Always available
+
+2. **IMU (Gyroscope)** - Measure heading
+   - Accuracy: ±2° (non-cumulative)
+   - Corrects heading drift
+
+3. **Vision (AprilTags)** - Detect position markers
+   - Accuracy: ±2" (when visible)
+   - Ground truth - resets drift
+
+## Fusion Strategy
+
+```
+if vision available:
+    position = vision (most accurate)
+    correct odometry
+elif IMU available:
+    position = odometry
+    heading = IMU
+else:
+    position = odometry only (dead reckoning)
+```
+
+## Fault Tolerance
+
+| Sensors | Accuracy | Confidence |
+|---------|----------|------------|
+| All 3 | ±2" | 100% |
+| Odometry + IMU | ±4" | 70% |
+| Odometry only | ±12" | 40% |
+
+System keeps working when sensors fail!
+
+## Usage
+
+```java
+RobotLocalizer localizer = new RobotLocalizer(odometry, imu, vision);
+localizer.setInitialPose(new Pose2D(12, 12, 0));
+
+while (opModeIsActive()) {
+    localizer.update();
+    
+    GridCell cell = localizer.getCurrentCell();
+    double confidence = localizer.getConfidence();
+    
+    // Make decisions based on position
+}
+```

+# Weevil Motor Cycle Demo - Architecture Overview
+
+## What This Example Demonstrates
+
+This is a minimal but complete FTC robot project showing how Weevil enables:
+1. Clean separation of business logic from hardware
+2. Unit testing on Windows JRE without FTC SDK
+3. Professional software architecture for robotics
+
+## The Problem Weevil Solves
+
+Traditional FTC projects:
+- Force you to edit SDK files directly (TeamCode folder)
+- Mix hardware dependencies with business logic
+- Make testing nearly impossible without a physical robot
+- Create monolithic OpMode classes that are hard to maintain
+
+## Weevil's Solution
+
+### Three-Layer Architecture
+
+```
+┌─────────────────────────────────┐
+│  OpMode (Integration Layer)    │  ← Only runs on robot
+│  - Wires everything together   │
+└─────────────────────────────────┘
+              ▼
+┌─────────────────────────────────┐
+│  Business Logic Layer           │  ← Runs everywhere!
+│  - MotorCycler                  │     Tests on Windows JRE
+│  - Pure Java, no FTC deps       │
+└─────────────────────────────────┘
+              ▼
+┌─────────────────────────────────┐
+│  Hardware Abstraction Layer     │  ← Interface + implementations
+│  - MotorController (interface)  │
+│  - FtcMotorController (robot)   │
+│  - MockMotorController (tests)  │
+└─────────────────────────────────┘
+```
+
+## File Breakdown
+
+### Hardware Abstraction (`src/main/java/robot/hardware/`)
+
+**MotorController.java** (17 lines)
+- Interface defining motor operations
+- No FTC SDK dependencies
+- Default methods for convenience
+
+**FtcMotorController.java** (19 lines)
+- Wraps FTC SDK's DcMotor
+- Only compiled when building for robot
+- Implements MotorController interface
+
+**MockMotorController.java** (27 lines - in test/)
+- Test implementation
+- Tracks state for assertions
+- No hardware required
+
+### Business Logic (`src/main/java/robot/subsystems/`)
+
+**MotorCycler.java** (95 lines)
+- Pure Java state machine
+- Time-based motor cycling
+- Zero FTC SDK dependencies
+- Fully testable in isolation
+
+Core design:
+```java
+public void update(long currentTimeMs) {
+    long elapsed = currentTimeMs - stateStartTime;
+    
+    switch (state) {
+        case OFF:
+            if (elapsed >= offDurationMs) {
+                motor.setPower(motorPower);
+                state = ON;
+                stateStartTime = currentTimeMs;
+            }
+            break;
+        case ON:
+            if (elapsed >= onDurationMs) {
+                motor.setPower(0.0);
+                state = OFF;
+                stateStartTime = currentTimeMs;
+            }
+            break;
+    }
+}
+```
+
+### Integration (`src/main/java/robot/opmodes/`)
+
+**MotorCycleOpMode.java** (44 lines)
+- FTC OpMode
+- Connects hardware to logic
+- Minimal glue code
+
+### Tests (`src/test/java/`)
+
+**MotorCyclerTest.java** (136 lines)
+- 9 comprehensive unit tests
+- Tests timing, state transitions, edge cases
+- Runs in milliseconds on PC
+- No robot or FTC SDK required
+
+Test coverage:
+- Initialization
+- State transitions (OFF→ON, ON→OFF)
+- Full cycle sequences
+- Time tracking
+- Stop functionality
+- Edge cases (default power, tiny power values)
+
+## Development Workflow
+
+### 1. Write Code Locally
+Edit files in `src/main/java/robot/` - your IDE works perfectly
+
+### 2. Test Immediately
+```bash
+gradlew test
+```
+- Runs in seconds on Windows
+- No robot connection needed
+- Full JUnit reports
+
+### 3. Deploy to Robot
+```bash
+build.bat    # Compiles everything, builds APK
+deploy.bat   # Copies APK to robot
+```
+
+## Why This Architecture Matters
+
+### For Students
+- Learn professional software engineering
+- Write testable code
+- Build confidence through tests
+- Debug logic without hardware
+
+### For Teams
+- Multiple programmers can work simultaneously
+- Test changes before robot practice
+- Catch bugs early (compile-time, not drive-time)
+- Build more complex robots with confidence
+
+### For Competitions
+- More reliable code
+- Faster iteration cycles
+- Better debugging capabilities
+- Professional development practices
+
+## Technical Benefits
+
+1. **Dependency Injection**: MotorCycler receives MotorController through constructor
+2. **Interface Segregation**: Clean interface with single responsibility
+3. **Testability**: Mock implementations enable isolated testing
+4. **Separation of Concerns**: Hardware, logic, and integration are distinct
+5. **Open/Closed Principle**: Easy to extend without modifying core logic
+
+## Comparison to Traditional FTC
+
+| Traditional FTC | Weevil Architecture |
+|----------------|---------------------|
+| Edit SDK files directly | Your code stays separate |
+| Mix hardware and logic | Clean separation |
+| No unit tests | Comprehensive tests |
+| Debug on robot only | Debug on PC first |
+| Monolithic OpModes | Modular subsystems |
+| Hard to maintain | Easy to understand |
+
+## Extending This Example
+
+Want to add more features? Keep the pattern:
+
+1. **Add Interface** in `hardware/` (e.g., `ServoController`)
+2. **Implement Logic** in `subsystems/` (e.g., `ArmController`)
+3. **Create Mock** in `test/hardware/`
+4. **Write Tests** in `test/subsystems/`
+5. **Wire in OpMode** - just a few lines of glue code
+
+The architecture scales from simple examples like this to complex multi-subsystem robots.
+
+## Real-World Application
+
+This demo shows the fundamentals. Real robots would have:
+- Multiple subsystems (drivetrain, arm, intake, etc.)
+- Command pattern for complex sequences
+- State machines for autonomous
+- Sensor integration (same abstraction pattern)
+- Configuration management
+
+All testable. All maintainable. All professional.
+
+---
+
+**This is what Weevil enables: writing robot code like professional software.**

+```
+
+## Code Flow
+
+1. **OpMode starts** → Creates FtcMotorController from hardware map
+2. **OpMode.init()** → Creates MotorCycler, passes controller
+3. **OpMode.loop()** → Calls motorCycler.update(currentTime)
+4. **MotorCycler** → Updates state, controls motor via interface
+5. **MotorController** → Abstraction hides whether it's real or mock
+
+## Testing Flow
+
+1. **Test creates** → MockMotorController
+2. **Test creates** → MotorCycler with mock
+3. **Test calls** → motorCycler.init()
+4. **Test calls** → motorCycler.update() with simulated time
+5. **Test verifies** → Mock motor received correct commands
+
+## Key Design Patterns
+
+### Dependency Injection
+```java
+// Good: Pass dependencies in constructor
+MotorCycler cycler = new MotorCycler(motorController, 2000, 1000);
+
+// Bad: Create dependencies internally
+// class MotorCycler { 
+//     DcMotor motor = hardwareMap.get(...); // Hard to test!
+// }
+```
+
+### Interface Abstraction
+```java
+// Good: Program to interface
+MotorController motor = new FtcMotorController(dcMotor);
+
+// Bad: Program to implementation
+// FtcMotorController motor = new FtcMotorController(dcMotor);
+```
+
+### Time-Based State Machine
+```java
+// Good: Pass time as parameter (testable)
+void update(long currentTimeMs) { ... }
+
+// Bad: Read time internally (hard to test)
+// void update() { 
+//     long time = System.currentTimeMillis(); 
+// }
+```
+
+## Common Tasks
+
+### Add a New Subsystem
+1. Create interface in `hardware/` (e.g., `ServoController.java`)
+2. Create FTC implementation (e.g., `FtcServoController.java`)
+3. Create business logic in `subsystems/` (e.g., `ClawController.java`)
+4. Create mock in `test/hardware/` (e.g., `MockServoController.java`)
+5. Create tests in `test/subsystems/` (e.g., `ClawControllerTest.java`)
+6. Wire into OpMode
+
+### Run a Specific Test
+```bash
+gradlew test --tests "MotorCyclerTest.testFullCycle"
+```
+
+### Debug Test Failure
+1. Look at test output (shows which assertion failed)
+2. Check expected vs actual values
+3. Add println() to MotorCycler if needed
+4. Re-run test instantly (no robot deploy needed!)
+
+### Modify Timing
+Edit MotorCycleOpMode.java line 20:
+```java
+// Change from 2000, 1000 to whatever you want
+motorCycler = new MotorCycler(motorController, 2000, 1000, 0.5);
+//                                             ^^^^  ^^^^  ^^^
+//                                             on-ms off-ms power
+```
+
+## Hardware Configuration
+
+Your FTC Robot Configuration needs:
+- **One DC Motor** named `"motor"` (exact spelling matters!)
+
+## Troubleshooting
+
+### "Could not find motor"
+→ Check hardware configuration has motor named "motor"
+
+### "Tests won't run"
+→ Make sure you're using `gradlew test` not `gradlew build`
+→ Tests run on PC, build needs FTC SDK
+
+### "Build can't find FTC SDK"
+→ Check `.weevil.toml` has correct `ftc_sdk_path`
+→ Run `weevil init` if SDK is missing
+
+### "Motor not cycling"
+→ Check OpMode is selected and started on Driver Station
+→ Verify motor is plugged in and configured correctly
+
+## Learning More
+
+- Read `ARCHITECTURE.md` for deep dive into design decisions
+- Read `README.md` for overview
+- Look at tests to see how each component works
+- Modify values and re-run tests to see behavior change
+
+## Best Practices
+
+✓ Write tests first (they're fast!)
+✓ Keep subsystems independent
+✓ Use interfaces for hardware
+✓ Pass time as parameters
+✓ Mock everything external
+
+✗ Don't put hardware maps in subsystems
+✗ Don't read System.currentTimeMillis() in logic
+✗ Don't skip tests
+✗ Don't mix hardware and logic code

+# FTC Robot Testing Showcase
+
+A comprehensive FTC robot project demonstrating **professional testing without hardware**.
+
+## What This Demonstrates
+
+This project shows how to build testable FTC robots using:
+- **Hardware abstraction** - Interfaces separate logic from FTC SDK
+- **Unit testing** - Test individual components in isolation
+- **System testing** - Test complete autonomous sequences
+- **Edge case testing** - Sensor failures, noise, boundary conditions
+
+**All tests run instantly on Windows - no robot needed!**
+
+## The Robot Systems
+
+### 1. Motor Cycler
+Continuously cycles a motor (2s ON, 1s OFF) - demonstrates timing logic
+
+### 2. Wall Approach
+Safely approaches a wall using distance sensor:
+- Drives fast when far away
+- Slows down as it gets closer
+- Stops at target distance
+- Handles sensor failures
+
+### 3. Turn Controller  
+Turns robot to target heading using gyro:
+- Proportional control (faster when far from target)
+- Chooses shortest rotation path
+- Handles 360° wraparound
+- Compensates for drift

+## Test Coverage
+
+**41 Total Tests:**
+- **Unit tests**: Individual component behaviors
+- **System tests**: Complete autonomous missions  
+- **Edge cases**: Sensor failures, noise, boundaries
+- **Integration**: Multiple subsystems working together
+
+Run time: **< 2 seconds on Windows!**
+
+## Building and Testing
+
+### Run Tests (Windows JRE)
+```bash
+gradlew test
+```
+Tests run on your local machine without requiring Android or FTC SDK.
+
+### Build APK for Robot (requires FTC SDK)
+```bash
+build.bat        # Windows
+./build.sh       # Linux/Mac
+```
+
+### Deploy to Robot
+```bash
+deploy.bat       # Windows  
+./deploy.sh      # Linux/Mac
+```
+
+## Hardware Configuration
+
+Configure your FTC robot with:
+- DC Motors named `"left_motor"` and `"right_motor"`
+- Distance sensor (REV 2m or similar)
+- IMU/Gyro sensor
+
+## Testing Showcase
+
+### Unit Test Example: Wall Approach
+```java
+@Test
+void testSlowsDownNearWall() {
+    sensor.setDistance(25.0);  // 25cm from wall
+    
+    wallApproach.start();
+    wallApproach.update();
+    
+    // Should slow down to 0.2 power
+    assertEquals(0.2, leftMotor.getPower(), 0.001);
+    assertEquals(WallApproachState.SLOWING, wallApproach.getState());
+}
+```
+
+### System Test Example: Complete Mission
+```java
+@Test
+void testCompleteAutonomousMission() {
+    // Simulate entire autonomous:
+    // 1. Drive to wall (100cm → 10cm)
+    // 2. Turn 90° right
+    // 3. Drive forward again
+    // 4. Turn back to original heading
+    
+    // All without a robot! Tests run in ~100ms
+}
+```
+
+### Edge Case Example: Sensor Failure
+```java
+@Test
+void testSensorFailureHandling() {
+    wallApproach.start();
+    
+    // Sensor suddenly fails!
+    sensor.simulateFailure();
+    wallApproach.update();
+    
+    // Should safely stop
+    assertEquals(WallApproachState.ERROR, wallApproach.getState());
+    assertEquals(0.0, motor.getPower());
+}
+```
+
+## What Tests Cover
+
+**Unit Tests** (test individual behaviors):
+- Motor timing and power levels
+- Distance threshold detection
+- Turn angle calculations
+- State transitions
+
+**System Tests** (test complete scenarios):
+- Full autonomous sequences
+- Multi-waypoint navigation
+- Square pattern driving
+- Sensor coordination
+
+**Edge Cases** (test failure modes):
+- Sensor failures and recovery
+- Noise handling
+- Boundary conditions
+- Wraparound math (0° ↔ 359°)
+
+**All 41 tests run in < 2 seconds on Windows!**
+
+## The Pattern: Applies to Any Hardware
+
+Same pattern works for **anything**:
+
+### Servo Example
+```java
+// Interface
+public interface ServoController {
+    void setPosition(double position);
+}
+
+// FTC impl (excluded from tests)
+public class FtcServoController implements ServoController {
+    private final Servo servo;  // FTC SDK class
+    ...
+}
+
+// Mock (for tests)
+public class MockServoController implements ServoController {
+    private double position = 0.5;
+    ...
+}
+```
+
+See `TESTING_GUIDE.md` for more examples (sensors, encoders, vision, etc.)
+
+## How It Works
+
+The architecture demonstrates three layers:
+
+1. **Hardware Abstraction** (`MotorController` interface)
+   - Defines what a motor can do
+   - Allows swapping implementations (real motor vs. mock)
+
+2. **Business Logic** (`MotorCycler` class)  
+   - Implements the cycling behavior
+   - Completely independent of FTC SDK
+   - Fully testable with mocks
+
+3. **Integration** (`MotorCycleOpMode`)
+   - Wires everything together
+   - Minimal code, just connects the pieces
+
+## Why This Matters
+
+Traditional FTC projects force you to edit SDK files directly and make testing difficult. 
+Weevil's approach:
+- ✓ Keep your code separate from the SDK
+- ✓ Write unit tests that run instantly on your PC
+- ✓ Build more reliable robots faster
+- ✓ Learn better software engineering practices

+# Solution: Testing FTC Code Without Hardware
+
+## The Problem
+
+When you run `gradlew test`, it tries to compile ALL your code including FTC-dependent files:
+```
+FtcMotorController.java → needs com.qualcomm.robotcore.hardware.DcMotor
+MotorCycleOpMode.java → needs com.qualcomm.robotcore.eventloop.opmode.OpMode
+```
+
+These classes don't exist on Windows → compilation fails → no tests.
+
+## The Solution (One Line)
+
+**Exclude FTC-dependent files from test compilation:**
+
+```kotlin
+// build.gradle.kts
+sourceSets {
+    main {
+        java {
+            exclude(
+                "robot/hardware/FtcMotorController.java",
+                "robot/opmodes/**/*.java"
+            )
+        }
+    }
+}
+```
+
+Done. That's it.
+
+## What Happens Now
+
+### When You Run `gradlew test`:
+- ✅ Compiles: MotorController.java (interface, no FTC deps)
+- ✅ Compiles: MotorCycler.java (pure Java logic)
+- ✅ Compiles: MockMotorController.java (test mock)
+- ✅ Compiles: MotorCyclerTest.java (tests)
+- ❌ Skips: FtcMotorController.java (EXCLUDED - has FTC deps)
+- ❌ Skips: MotorCycleOpMode.java (EXCLUDED - has FTC deps)
+
+Tests run on Windows in seconds!
+
+### When You Run `build.bat`:
+- Copies ALL files to FTC SDK TeamCode directory
+- FTC SDK's Gradle compiles everything (it has the FTC SDK jars)
+- Creates APK with all your code
+
+## The Architecture Pattern
+
+```
+Interface (no FTC) → Logic uses interface → Test with mock
+    ↓
+FTC Implementation (excluded from tests)
+```
+
+### Example: Motor
+```java
+// 1. Interface (compiles for tests)
+public interface MotorController {
+    void setPower(double power);
+}
+
+// 2. FTC implementation (excluded from tests)
+public class FtcMotorController implements MotorController {
+    private final DcMotor motor;  // FTC SDK class
+    public void setPower(double p) { motor.setPower(p); }
+}
+
+// 3. Mock (test only)
+public class MockMotorController implements MotorController {
+    private double power;
+    public void setPower(double p) { this.power = p; }
+}
+
+// 4. Logic (pure Java - testable!)
+public class MotorCycler {
+    private final MotorController motor;  // Uses interface!
+    // ... no FTC dependencies ...
+}
+
+// 5. Test
+@Test
+void test() {
+    MockMotorController mock = new MockMotorController();
+    MotorCycler cycler = new MotorCycler(mock, 100, 50);
+    cycler.update(60);
+    assertEquals(0.5, mock.getPower());
+}
+```
+
+## Applies to Any Hardware
+
+Same pattern for everything:
+- **Motors** → MotorController interface + Ftc + Mock
+- **Servos** → ServoController interface + Ftc + Mock
+- **Sensors** (I2C, SPI, USB, etc.) → SensorInterface + Ftc + Mock
+- **Gyros** → GyroSensor interface + Ftc + Mock
+
+The FTC implementation is always just a thin wrapper. All your logic uses interfaces and is fully testable.
+
+## Why This Works
+
+**Test compilation:**
+- Only compiles files WITHOUT FTC dependencies
+- Pure Java logic + interfaces + mocks
+- Runs on Windows JRE
+
+**Robot compilation:**
+- ALL files copied to TeamCode
+- Compiled by FTC SDK (which has FTC jars)
+- Creates APK with everything
+
+Same logic runs in both places - no special test-only code!
+
+## Quick Start
+
+1. Create interface (no FTC deps)
+2. Create FTC implementation (add to exclude list)
+3. Create mock for testing
+4. Write pure Java logic using interface
+5. Test instantly on PC
+6. Deploy to robot - everything works

+# Testing Guide: Mocking Hardware Without the Robot
+
+## The Problem
+
+When you run `gradlew test`, Gradle tries to compile **all** your main source code, including files that depend on the FTC SDK (like `FtcMotorController` and `MotorCycleOpMode`). Since the FTC SDK isn't available on your Windows machine, compilation fails.
+
+## The Solution: Source Set Exclusion
+
+Your `build.gradle.kts` now excludes FTC-dependent files from test compilation:
+
+```kotlin
+sourceSets {
+    main {
+        java {
+            exclude(
+                "robot/hardware/FtcMotorController.java",
+                "robot/opmodes/**/*.java"
+            )
+        }
+    }
+}
+```
+
+This means:
+- ✅ `MotorController.java` (interface) - Compiles for tests
+- ✅ `MotorCycler.java` (pure logic) - Compiles for tests  
+- ✅ `MockMotorController.java` (test mock) - Compiles for tests
+- ❌ `FtcMotorController.java` (FTC SDK) - Skipped for tests
+- ❌ `MotorCycleOpMode.java` (FTC SDK) - Skipped for tests
+
+## Running Tests
+
+```bash
+# On Windows
+gradlew test
+
+# On Linux/Mac
+./gradlew test
+```
+
+The tests run entirely on your Windows JRE - **no robot, no Android, no FTC SDK needed!**
+
+## The Architecture Pattern
+
+### 1. Interface (Hardware Abstraction)
+```java
+public interface MotorController {
+    void setPower(double power);
+    double getPower();
+}
+```
+
+### 2. Real Implementation (FTC-dependent)
+```java
+public class FtcMotorController implements MotorController {
+    private final DcMotor motor;  // FTC SDK class
+    
+    public FtcMotorController(DcMotor motor) {
+        this.motor = motor;
+    }
+    
+    @Override
+    public void setPower(double power) {
+        motor.setPower(power);
+    }
+    
+    @Override
+    public double getPower() {
+        return motor.getPower();
+    }
+}
+```
+
+### 3. Mock Implementation (Testing)
+```java
+public class MockMotorController implements MotorController {
+    private double power = 0.0;
+    
+    @Override
+    public void setPower(double power) {
+        this.power = power;
+    }
+    
+    @Override
+    public double getPower() {
+        return power;
+    }
+}
+```
+
+### 4. Business Logic (Pure Java)
+```java
+public class MotorCycler {
+    private final MotorController motor;  // Interface, not FTC class!
+    
+    public MotorCycler(MotorController motor, long onMs, long offMs) {
+        this.motor = motor;
+        // ...
+    }
+    
+    public void update(long currentTimeMs) {
+        // Time-based state machine
+        // No FTC SDK dependencies!
+    }
+}
+```
+
+## Example: I2C Bump Sensor
+
+Here's how you'd implement the pattern for an I2C bump sensor:
+
+### Interface
+```java
+// src/main/java/robot/hardware/BumpSensor.java
+package robot.hardware;
+
+public interface BumpSensor {
+    /**
+     * Check if the sensor detects contact.
+     * @return true if bumped, false otherwise
+     */
+    boolean isBumped();
+    
+    /**
+     * Get the force reading (0.0 to 1.0).
+     * @return force value
+     */
+    double getForce();
+}
+```
+
+### FTC Implementation
+```java
+// src/main/java/robot/hardware/FtcBumpSensor.java
+package robot.hardware;
+
+import com.qualcomm.robotcore.hardware.I2cDevice;
+import com.qualcomm.robotcore.hardware.I2cDeviceReader;
+
+public class FtcBumpSensor implements BumpSensor {
+    private final I2cDevice sensor;
+    private final I2cDeviceReader reader;
+    private static final double BUMP_THRESHOLD = 0.5;
+    
+    public FtcBumpSensor(I2cDevice sensor) {
+        this.sensor = sensor;
+        this.reader = new I2cDeviceReader(sensor, 0x00, 2);
+    }
+    
+    @Override
+    public boolean isBumped() {
+        return getForce() > BUMP_THRESHOLD;
+    }
+    
+    @Override
+    public double getForce() {
+        byte[] data = reader.read();
+        // Convert I2C bytes to force value
+        int raw = ((data[0] & 0xFF) << 8) | (data[1] & 0xFF);
+        return raw / 65535.0;
+    }
+}
+```
+
+### Mock Implementation
+```java
+// src/test/java/robot/hardware/MockBumpSensor.java
+package robot.hardware;
+
+public class MockBumpSensor implements BumpSensor {
+    private double force = 0.0;
+    
+    /**
+     * Simulate hitting a wall with given force.
+     */
+    public void simulateImpact(double force) {
+        this.force = Math.max(0.0, Math.min(1.0, force));
+    }
+    
+    /**
+     * Simulate sensor returning to neutral.
+     */
+    public void reset() {
+        this.force = 0.0;
+    }
+    
+    @Override
+    public boolean isBumped() {
+        return force > 0.5;
+    }
+    
+    @Override
+    public double getForce() {
+        return force;
+    }
+}
+```
+
+### Business Logic Using Sensor
+```java
+// src/main/java/robot/subsystems/CollisionDetector.java
+package robot.subsystems;
+
+import robot.hardware.BumpSensor;
+import robot.hardware.MotorController;
+
+public class CollisionDetector {
+    private final BumpSensor sensor;
+    private final MotorController motor;
+    private boolean collisionDetected = false;
+    
+    public CollisionDetector(BumpSensor sensor, MotorController motor) {
+        this.sensor = sensor;
+        this.motor = motor;
+    }
+    
+    public void update() {
+        if (sensor.isBumped() && !collisionDetected) {
+            // First detection - stop the motor
+            motor.setPower(0.0);
+            collisionDetected = true;
+        } else if (!sensor.isBumped() && collisionDetected) {
+            // Sensor cleared - reset flag
+            collisionDetected = false;
+        }
+    }
+    
+    public boolean hasCollision() {
+        return collisionDetected;
+    }
+}
+```
+
+### Test with Simulated Wall Hit
+```java

+        detector.update();
+        assertTrue(detector.hasCollision());
+    }
+}
+```
+
+## Key Benefits
+
+### 1. **Test Real Scenarios Without Hardware**
+```java
+@Test
+void testRobotBouncesOffWall() {
+    // Simulate approach
+    motor.setPower(0.8);
+    
+    // Hit wall
+    sensor.simulateImpact(0.9);
+    detector.update();
+    
+    // Verify emergency stop
+    assertEquals(0.0, motor.getPower());
+}
+```
+
+### 2. **Test Edge Cases**
+```java
+@Test
+void testSensorNoise() {
+    // Simulate sensor flutter at threshold
+    sensor.simulateImpact(0.49);
+    detector.update();
+    assertFalse(detector.hasCollision());
+    
+    sensor.simulateImpact(0.51);
+    detector.update();
+    assertTrue(detector.hasCollision());
+}
+```
+
+### 3. **Test Timing Issues**
+```java
+@Test
+void testRapidImpacts() {
+    for (int i = 0; i < 10; i++) {
+        sensor.simulateImpact(0.8);
+        detector.update();
+        assertTrue(detector.hasCollision());
+        
+        sensor.reset();
+        detector.update();
+    }
+}
+```
+
+### 4. **Integration Tests**
+```java
+@Test
+void testFullDriveSequence() {
+    // Drive forward
+    motor.setPower(0.5);
+    for (int i = 0; i < 10; i++) {
+        detector.update();
+        assertFalse(detector.hasCollision());
+    }
+    
+    // Hit obstacle
+    sensor.simulateImpact(0.8);
+    detector.update();
+    assertEquals(0.0, motor.getPower());
+    
+    // Back up
+    motor.setPower(-0.3);
+    sensor.reset();
+    detector.update();
+    
+    // Continue backing
+    for (int i = 0; i < 5; i++) {
+        detector.update();
+        assertEquals(-0.3, motor.getPower());
+    }
+}

+
+## Build Configuration Rules
+
+In `build.gradle.kts`:
+
+```kotlin
+sourceSets {
+    main {
+        java {
+            // Exclude all FTC-dependent code from test compilation
+            exclude(
+                "robot/hardware/Ftc*.java",  // All FTC implementations
+                "robot/opmodes/**/*.java"     // All OpModes
+            )
+        }
+    }
+}
+```
+
+This pattern ensures:
+- ✅ Interfaces and pure logic compile for tests
+- ✅ Mocks are available in test classpath
+- ✅ Tests run on Windows JRE instantly
+- ✅ FTC-dependent code is deployed and compiled on robot
+- ✅ Same logic runs in tests and on robot
+
+## Advanced Mocking Patterns
+
+### Stateful Mock (Servo with Position Memory)
+```java
+public class MockServo implements ServoController {
+    private double position = 0.5;
+    private double speed = 1.0;  // Instant by default
+    
+    public void setSpeed(double speed) {
+        this.speed = speed;
+    }
+    
+    @Override
+    public void setPosition(double target) {
+        // Simulate gradual movement
+        double delta = target - position;
+        position += delta * speed;
+        position = Math.max(0.0, Math.min(1.0, position));
+    }
+    
+    @Override
+    public double getPosition() {
+        return position;
+    }
+}
+```
+
+### Mock with Latency
+```java
+public class MockGyro implements GyroSensor {
+    private double heading = 0.0;
+    private long lastUpdateTime = 0;
+    private double drift = 0.1;  // Degrees per second drift
+    
+    public void simulateRotation(double degrees, long timeMs) {
+        heading += degrees;
+        heading = (heading + 360) % 360;
+        lastUpdateTime = timeMs;
+    }
+    
+    @Override
+    public double getHeading(long currentTime) {
+        // Simulate sensor drift over time
+        long elapsed = currentTime - lastUpdateTime;
+        double driftError = (elapsed / 1000.0) * drift;
+        return (heading + driftError) % 360;
+    }
+}
+```
+
+### Mock with Failure Modes
+```java
+public class MockDistanceSensor implements DistanceSensor {
+    private double distance = 100.0;
+    private boolean connected = true;
+    private double noise = 0.0;
+    
+    public void simulateDisconnect() {
+        connected = false;
+    }
+    
+    public void setNoise(double stdDev) {
+        this.noise = stdDev;
+    }
+    
+    @Override
+    public double getDistance() throws SensorException {
+        if (!connected) {
+            throw new SensorException("Sensor disconnected");
+        }
+        
+        // Add Gaussian noise
+        double noisyDistance = distance + (Math.random() - 0.5) * noise;
+        return Math.max(0, noisyDistance);
+    }
+}
+```
+
+## Why This Matters
+
+Traditional FTC development:
+- ❌ Can't test without robot
+- ❌ Long iteration cycles (code → deploy → test → repeat)
+- ❌ Hard to test edge cases
+- ❌ Integration issues found late
+
+Weevil + proper mocking:
+- ✅ Test instantly on PC
+- ✅ Rapid iteration (code → test → fix)
+- ✅ Comprehensive edge case coverage
+- ✅ Catch bugs before robot practice
+
+**You're not just testing motor values - you're simulating complete scenarios: wall collisions, sensor failures, timing issues, state machines, everything!**
+
+This is professional robotics software engineering.

+# Testing Showcase: Professional Robotics Without Hardware
+
+This project demonstrates **industry-standard testing practices** for robotics code.
+
+## The Revolutionary Idea
+
+**You can test robot logic without a robot!**
+
+Traditional FTC:
+- Write code
+- Deploy to robot (5+ minutes)
+- Test on robot
+- Find bug
+- Repeat...
+
+With proper testing:
+- Write code
+- Run tests (2 seconds)
+- Fix bugs instantly
+- Deploy confident code to robot
+
+## Test Categories in This Project
+
+### 1. Unit Tests (Component-Level)
+
+Test individual behaviors in isolation.
+
+**Example: Motor Power Levels**
+```java
+@Test
+void testFullSpeedWhenFar() {
+    sensor.setDistance(100.0);  // Far from wall
+    
+    wallApproach.start();
+    wallApproach.update();
+    
+    assertEquals(0.6, motor.getPower(), 0.001,  // Full speed
+        "Should drive at full speed when far");
+}
+```
+
+**What this tests:**
+- Speed control logic
+- Distance threshold detection
+- Motor power calculation
+
+**Time to run:** ~5 milliseconds
+
+### 2. System Tests (Complete Scenarios)
+
+Test entire sequences working together.
+
+**Example: Complete Autonomous Mission**
+```java
+@Test
+void testCompleteAutonomousMission() {
+    // Phase 1: Drive 100cm to wall
+    distanceSensor.setDistance(100.0);
+    wallApproach.start();
+    
+    while (wallApproach.getState() != STOPPED) {
+        wallApproach.update();
+        distanceSensor.approach(motor.getPower() * 2.0);
+    }
+    
+    // Phase 2: Turn 90° right
+    turnController.turnTo(90);
+    
+    while (turnController.getState() == TURNING) {
+        turnController.update();
+        gyro.rotate(motor.getPower() * 2.0);
+    }
+    
+    // Verify complete mission success
+    assertEquals(STOPPED, wallApproach.getState());
+    assertEquals(90, gyro.getHeading(), 2.0);
+}
+```
+
+**What this tests:**
+- Multiple subsystems coordinating
+- State transitions between phases
+- Sensor data flowing correctly
+- Complete mission execution
+
+**Time to run:** ~50 milliseconds
+
+### 3. Edge Case Tests (Failure Modes)
+
+Test things that are hard/dangerous to test on a real robot.
+
+**Example: Sensor Failure**
+```java
+@Test
+void testSensorFailureHandling() {
+    wallApproach.start();
+    
+    // Sensor suddenly disconnects!
+    sensor.simulateFailure();
+    wallApproach.update();
+    
+    // Robot should safely stop
+    assertEquals(ERROR, wallApproach.getState());
+    assertEquals(0.0, motor.getPower());
+    assertTrue(wallApproach.hasSensorError());
+}
+```
+
+**What this tests:**
+- Error detection
+- Safe shutdown procedures
+- Graceful degradation
+- Diagnostic reporting
+
+**Time to run:** ~2 milliseconds
+
+**Why this matters:**
+- Can't safely disconnect sensors on real robot during testing
+- Would risk crashing robot into wall
+- Tests this scenario hundreds of times instantly
+
+### 4. Integration Tests (System-Level)
+
+Test multiple subsystems interacting realistically.
+
+**Example: Square Pattern Navigation**
+```java
+@Test
+void testSquarePattern() {
+    for (int side = 1; side <= 4; side++) {
+        // Drive forward to wall
+        distanceSensor.setDistance(50.0);
+        wallApproach.start();
+        simulateDriving();
+        
+        // Turn 90° right
+        turnController.turnTo(side * 90);
+        simulateTurning();
+    }
+    
+    // Should complete square and face original direction
+    assertTrue(Math.abs(gyro.getHeading()) <= 2.0);
+}
+```
+
+**What this tests:**
+- Sequential operations
+- Repeated patterns
+- Accumulated errors
+- Return to starting position
+
+**Time to run:** ~200 milliseconds
+
+## Real-World Scenarios You Can Test
+
+### Scenario 1: Approaching Moving Target
+
+```java
+@Test
+void testApproachingMovingTarget() {
+    distanceSensor.setDistance(100.0);
+    wallApproach.start();
+    
+    for (int i = 0; i < 50; i++) {
+        wallApproach.update();
+        
+        // Target is also moving away!
+        distanceSensor.approach(motor.getPower() * 2.0 - 0.5);
+        
+        // Robot should still eventually catch up
+    }
+    
+    assertTrue(distanceSensor.getDistanceCm() < 15.0);
+}
+```
+
+### Scenario 2: Noisy Sensor Data
+
+```java
+@Test
+void testHandlesNoisySensors() {
+    sensor.setNoise(2.0);  // ±2cm random jitter
+    sensor.setDistance(50.0);
+    wallApproach.start();
+    
+    // Run 100 updates with noisy data
+    for (int i = 0; i < 100; i++) {
+        wallApproach.update();
+        sensor.approach(0.5);
+        
+        // Should not oscillate wildly or crash
+        assertTrue(motor.getPower() >= 0);
+        assertTrue(motor.getPower() <= 1.0);
+    }
+}
+```
+
+### Scenario 3: Gyro Drift Compensation
+
+```java
+@Test
+void testCompensatesForGyroDrift() {
+    gyro.setHeading(0);
+    gyro.setDrift(0.5);  // 0.5° per second drift
+    
+    turnController.turnTo(90);
+    
+    // Simulate turn with drift
+    for (int i = 0; i < 100; i++) {
+        turnController.update();
+        gyro.rotate(motor.getPower() * 2.0);
+        Thread.sleep(10);  // Let drift accumulate
+    }
+    
+    // Should still reach target despite drift
+    assertTrue(Math.abs(gyro.getHeading() - 90) <= 2.0);
+}
+```
+
+### Scenario 4: Battery Voltage Drop
+
+```java
+@Test
+void testLowBatteryCompensation() {
+    MockBattery battery = new MockBattery();
+    MotorController motor = new VoltageCompensatedMotor(battery);
+    
+    // Full battery
+    battery.setVoltage(12.5);
+    motor.setPower(0.5);
+    assertEquals(0.5, motor.getActualPower());
+    
+    // Low battery
+    battery.setVoltage(11.0);
+    motor.setPower(0.5);
+    assertTrue(motor.getActualPower() > 0.5,  // Compensated up
+        "Should increase power to compensate for voltage drop");
+}
+```

+2. **Safe experimentation** - Can't break robot in tests
+3. **Professional skills** - Industry-standard practices
+4. **Better code** - Testable code is well-designed code
+5. **Confidence** - Know it works before deploying
+
+## Comparison
+
+### Traditional FTC Development
+
+```
+Write code (10 min)
+  ↓
+Deploy to robot (5 min)
+  ↓
+Test on robot (10 min)
+  ↓
+Find bug
+  ↓
+Repeat...
+
+Time per iteration: ~25 minutes
+Bugs found: Late (on robot)
+Risk: High (can damage robot)
+```
+
+### With Testing
+
+```
+Write code (10 min)
+  ↓
+Run tests (2 sec)
+  ↓
+Fix bugs immediately (5 min)
+  ↓
+Deploy confident code (5 min)
+  ↓
+Works on robot!
+
+Time per iteration: ~20 minutes (first deploy!)
+Bugs found: Early (in tests)
+Risk: Low (robot rarely crashes)
+```
+
+## Advanced Testing Patterns
+
+### Parameterized Tests
+
+Test the same logic with different inputs:
+
+```java
+@ParameterizedTest
+@ValueSource(doubles = {10, 20, 30, 40, 50})
+void testDifferentStopDistances(double distance) {
+    sensor.setDistance(100.0);
+    wallApproach = new WallApproach(sensor, motor, distance);
+    wallApproach.start();
+    
+    simulateDriving();
+    
+    assertTrue(sensor.getDistanceCm() <= distance + 2);
+}
+```
+
+### State Machine Verification
+
+Test all state transitions:
+
+```java
+@Test
+void testAllStateTransitions() {
+    // INIT → APPROACHING
+    wallApproach.start();
+    assertEquals(APPROACHING, wallApproach.getState());
+    
+    // APPROACHING → SLOWING
+    sensor.setDistance(25.0);
+    wallApproach.update();
+    assertEquals(SLOWING, wallApproach.getState());
+    
+    // SLOWING → STOPPED
+    sensor.setDistance(10.0);
+    wallApproach.update();
+    assertEquals(STOPPED, wallApproach.getState());
+    
+    // STOPPED → STOPPED (stays stopped)
+    wallApproach.update();
+    assertEquals(STOPPED, wallApproach.getState());
+}
+```
+
+### Performance Testing
+
+Verify code runs fast enough:
+
+```java
+@Test
+void testUpdatePerformance() {
+    long startTime = System.nanoTime();
+    
+    for (int i = 0; i < 1000; i++) {
+        wallApproach.update();
+    }
+    
+    long elapsedMs = (System.nanoTime() - startTime) / 1_000_000;
+    
+    assertTrue(elapsedMs < 100,
+        "1000 updates should complete in < 100ms");
+}
+```
+
+## Conclusion
+
+Testing without hardware is **not a compromise** - it's actually **better**:
+
+- Faster development
+- Safer testing
+- More thorough coverage
+- Professional practices
+
+This is how real robotics companies (Boston Dynamics, Tesla, SpaceX) develop robots.
+
+Your students are learning the same techniques used to land rockets and build autonomous vehicles!
