+# Testing
+
+The project includes a comprehensive test suite covering unit and integration tests.
+
+## Running Tests
+
+To run all passing unit tests:
+
+```bash
+cargo test
+```
+
+This will run 20+ unit tests that don't require external dependencies.
+
+## Integration Tests
+
+Some tests are marked as ignored because they require environment variables and external API access. To run these tests, first set up the required environment variables:
+
+```bash
+export GOVEE_API_KEY="your_govee_api_key"
+export ACCESS_TOKEN="your_access_token"
+export GOVEE_ROOT_URL="https://developer-api.govee.com"
+# ... plus all OFFICE_* device environment variables
+```
+
+Then run all tests including ignored ones:
+
+```bash
+cargo test -- --ignored
+```
+
+Or run all tests together:
+
+```bash
+cargo test -- --include-ignored
+```
+
+## Test Coverage
+
+The test suite covers:
+- **Wrapper functions**: Device data transformation and mapping
+- **Error handlers**: Error response formatting and serialization
+- **Route handlers**: HTTP endpoint behavior (healthcheck, home redirect)
+- **Service layer**: Light setup and device control logic
+- **Data structures**: Constants, enums, and type definitions
+- **Authorization**: Token validation and authentication flows

+This document provides detailed information about the test suite for the Cyberlight project.
+
+## Test Organization
+
+Tests are organized in the `src/tests/` directory with the following structure:
+
+```
+src/tests/

+│   └── test_enums.rs

+```
+
+## Test Categories
+
+### Unit Tests (No External Dependencies)
+
+These tests run without requiring environment variables or external API access:
+
+1. **Wrapper Tests** (`test_wrappers/`)
+   - `test_wrap_devices`: Tests device data transformation
+   - `test_wrap_model_and_devices`: Tests model and device mapping
+   - `test_wrap_device_status`: Tests device status filtering
+
+2. **Error Implementation Tests** (`test_error_handlers/test_error_implementations.rs`)
+   - Serialization/deserialization of error types
+   - AuthError, NotFoundError, ServerError handling
+
+3. **Service Tests** (`test_services/`)
+   - `test_office_setup_creates_payload_with_on_command`: Tests on command payload creation
+   - `test_office_setup_creates_payload_with_off_command`: Tests off command payload creation
+   - `test_office_setup_handles_all_device_types`: Tests all device type variants
+
+4. **Constants Tests** (`test_constants/`)
+   - Device struct creation and field access
+   - OfficeDevices enum variants
+   - All device types can be instantiated
+
+5. **Route Tests** (`test_routes/`)
+   - `test_healthcheck_handler`: Tests healthcheck endpoint response
+   - `test_home_redirects_to_status`: Tests home route redirect behavior
+   - Error handler tests (404, 401, 500)
+
+### Integration Tests (Require Environment Setup)
+
+These tests are marked with `#[ignore]` and require environment variables:
+
+1. **API Integration Tests** (`test_routes/test_all_devices_routes.rs`)
+   - `test_get_all_devices_handler`: Requires `GOVEE_API_KEY`
+   - `test_get_status_for_all_devices`: Requires `GOVEE_API_KEY`
+   - `test_get_status_for_device`: Requires `GOVEE_API_KEY`
+
+2. **Authorization Tests** (`test_implementations/test_access_token.rs`)
+   - `test_valid_authorization_token`: Requires `ACCESS_TOKEN`, `GOVEE_API_KEY`
+   - `test_missing_authorization_header`: Requires `ACCESS_TOKEN`
+   - `test_invalid_authorization_token`: Requires `ACCESS_TOKEN`
+
+## Running Tests
+
+### Run All Unit Tests
+```bash
+cargo test
+```
+Expected output: 20+ tests passing, 6 tests ignored
+
+### Run Specific Test Module
+```bash
+# Run wrapper tests only
+cargo test test_wrap
+
+# Run error handler tests only
+cargo test test_error
+
+# Run service tests only
+cargo test test_light_setup
+```
+
+### Run Integration Tests
+
+First, set up environment variables (create a `.env` file or export them):
+
+```bash
+# Required for API integration tests
+export GOVEE_API_KEY="your_govee_api_key"
+export GOVEE_ROOT_URL="https://developer-api.govee.com"
+export ACCESS_TOKEN="your_access_token"
+
+# Required for device control tests
+export OFFICE_BOARD_LED_ID="your_board_led_id"
+export OFFICE_BOARD_LED_MODEL="your_board_led_model"
+export OFFICE_TABLE_LED_ID="your_table_led_id"
+export OFFICE_TABLE_LED_MODEL="your_table_led_model"
+export OFFICE_WINDOW_LED_ID="your_window_led_id"
+export OFFICE_WINDOW_LED_MODEL="your_window_led_model"
+export OFFICE_STANDING_LEFT_LED_ID="your_standing_left_led_id"
+export OFFICE_STANDING_LEFT_LED_MODEL="your_standing_left_led_model"
+export OFFICE_STANDING_RIGHT_LED_ID="your_standing_right_led_id"
+export OFFICE_STANDING_RIGHT_LED_MODEL="your_standing_right_led_model"
+export OFFICE_HUMIDIFIER_ID="your_humidifier_id"
+export OFFICE_HUMIDIFIER_MODEL="your_humidifier_model"
+```
+
+Then run the ignored tests:
+
+```bash
+# Run only ignored tests
+cargo test -- --ignored
+
+# Run all tests (including ignored ones)
+cargo test -- --include-ignored
+```
+
+## Test Maintenance
+
+When adding new features, please ensure:
+
+1. **Unit tests** are added for pure functions and logic that doesn't require external dependencies
+2. **Integration tests** are added for API endpoints and routes
+3. Tests requiring environment variables are marked with `#[ignore = "reason"]`
+4. Test names clearly describe what is being tested
+5. Tests are organized in the appropriate test module
+
+## Coverage Improvements Made
+
+The recent test suite enhancements include:
+
+- ✅ Uncommented and fixed wrapper tests (3 tests)
+- ✅ Added home route redirect test (1 test)
+- ✅ Added service layer tests (3 tests)
+- ✅ Added error implementation tests (6 tests)
+- ✅ Added constants/enums tests (3 tests)
+- ✅ Marked integration tests as ignored when environment variables are not set
+- ✅ Organized tests into logical modules
+
+Total: 20+ passing unit tests, 6 integration tests (ignored by default)
+
+## Continuous Integration
+
+In CI/CD pipelines, you can:
+
+1. Run unit tests without environment setup: `cargo test`
+2. Set up environment secrets and run all tests: `cargo test -- --include-ignored`
+
+## Future Test Improvements
+
+Potential areas for additional test coverage:
+
+- Mock external API calls for integration tests
+- Add performance/benchmark tests for critical paths
+- Add property-based tests for data transformations
+- Add tests for edge cases and error conditions in routes
+- Add tests for concurrent request handling
