run-tests

Builds and runs the host-side unit tests in code/test/ using CMake and ctest. The tests use mocked Arduino/hardware interfaces and run on the development machine — they do not touch the Teensy.

Setting	Value
Source dir	code/test/
Build dir	code/test/build/
Test runner	ctest (Google Test discovered via CMake)

Steps

1. Ensure the build directory exists. If code/test/build/ is missing, create it. If the user passed clean, remove it first and recreate.

   mkdir -p code/test/build
   

2. Configure (if needed). From code/test/build/, run cmake. CMake re-configures itself on subsequent runs as needed, so it's safe to run unconditionally:

   cmake ..
   

3. Build. From code/test/build/:

   make
   

   Builds can take a while on a clean tree; use a generous Bash timeout (e.g. 600000 ms). If the build fails, surface the first error and stop — do not run tests on a broken build.

4. Run tests. From code/test/build/:

   ctest --output-on-failure
   

   Add -R <pattern> if the user passed a filter arg, and -V if they passed verbose.

5. Report. Summarise in 1–2 lines: how many tests passed/failed, and the names of any failing tests. If a specific filter was used, mention what it matched.

Args

• clean — wipe code/test/build/ and reconfigure from scratch before building. Use when CMake state seems stale or the user explicitly asks for a clean build.
• verbose — pass -V to ctest so individual test output is shown even on success.
• Any other arg — treat as a ctest -R regex filter (e.g. RFBoard runs ctest -R RFBoard --output-on-failure). Multiple words can be combined into one regex with |.

clean and verbose may be combined with a filter arg.

Notes

• Always run from code/test/build/ once it exists — relative paths in CMakeLists.txt assume that.
• This skill is for host unit tests only. To build/flash the firmware itself, use the flash-radio skill instead.
• The CMake test build lives under code/test/build/; the firmware build artifacts (code/build/, ArduinoOutput/) are unrelated and should not be touched here.
