Create Tests

Write tests for recent implementation work. Analyzes changes and produces appropriate test coverage.

Process

1. Identify scope: Run git diff main...HEAD --stat to see what changed. If the user specifies files or a feature, scope to that instead.

2. Check for existing tests: Changed files may already have test files. Read them first — add new test cases to existing files rather than creating duplicates.

3. Analyze and write tests:

   • Focus on logic, branching, edge cases, error handling
   • Skip trivial getters/setters/CRUD
   • Mock external dependencies — don't require running services
   • Follow the project's existing test conventions (framework, file organization, mocking patterns)

4. Verify: Run the project's test command to confirm all tests pass.

5. Commit: Commit test files with message test: add tests for <feature>

What to Test

• Business logic and branching paths
• Error handling and edge cases
• Integration points (with mocked dependencies)
• Anything that would break silently without tests

What NOT to Test

• Pure configuration files
• Simple type definitions
• Trivial pass-through functions
• Generated code
