# Unity/Ceedling Test Skill ## Overview This skill provides embedded unit testing capabilities using the Unity test framework, CMock mock generation, and Ceedling build system for comprehensive off-target and on-target testing. ## Capabilities ### Unity Test Framework - Test case generation - Assertion macro usage - Test fixture setup/teardown - Test group organization - Parameterized tests - Custom assertions ### CMock Mock Generation - Automatic mock generation from headers - HAL/driver mocking strategies - Callback mocking - Argument capture and validation - Return value configuration - Call count verification ### Ceedling Build System - Project configuration (project.yml) - Test runner generation - Coverage integration - Compiler configuration - Plugin management - CI/CD integration ### Hardware Abstraction Mocking - Register mock strategies - DMA mock patterns - Interrupt mock handling - Timing mock approaches - State machine mocking ### Test Coverage - gcov integration - lcov report generation - Branch coverage analysis - MC/DC coverage (for safety) - Coverage threshold enforcement ### Off-Target Testing - Host compilation setup - Platform abstraction - Stub implementation - Double buffering for DMA - Fake timer implementations ## Target Processes - `embedded-unit-testing.js` - Unit test implementation - `device-driver-development.js` - Driver testing - `bsp-development.js` - BSP unit testing ## Dependencies - Unity test framework - CMock mock generator - C...
