Write Tests

Generate, structure, and organize MATLAB unit tests using the matlab.unittest and matlab.uitest frameworks.

When to Use

• User asks to write tests for a MATLAB function or class
• User wants to add test methods or parameterize existing tests
• User needs fixtures, mocking, or dependency injection in tests
• Test-driven development — writing tests before implementation
• Testing App Designer apps with programmatic gestures
• Baseline/regression tests against stored reference data (golden file, snapshot, characterization tests)

When NOT to Use

• Running tests, analyzing failures, or filtering test suites — use matlab-run-tests
• Collecting or analyzing code coverage — use matlab-run-tests
• CI/CD pipeline configuration — use matlab-run-tests
• Testing Simulink models — use Simulink test skills
