 **Commit Policy**: Always run tests before committing. Refer to `CONTRIBUTING.md` for details.
 
-To build and run the tests, you need to enable the `DEMO_BUILD_TESTS` option in CMake.
+To build and run the tests, you need to enable the `DEMO_BUILD_TESTS` option in CMake. Refer to the "Developer Build (All Options)" section for the easiest way to enable this.
 
 Available test suites:
 *   `HammingWindowTest`: Verifies the properties of the Hamming window function.
+*   `MathUtilsTest`: Verifies basic math utilities.
 *   `SynthEngineTest`: Verifies the core functionality of the audio synthesizer.
 *   `SpectoolEndToEndTest`: Performs an end-to-end test of the `spectool` by generating a WAV file, analyzing it, and verifying the output.
+*   `SequenceSystemTest`: Tests the logic of the sequence and effect system (activation, timing, priority), but **not** actual GPU rendering output, as this requires extensive mocking.
