# Generate tests Generate comprehensive tests for specified code. ## Instructions 1. Read the target file(s) 2. Identify testable units (functions, classes, methods) 3. Generate tests following project conventions 4. Ensure high coverage of edge cases ## Test generation process ### 1. Analyze target - Identify public interfaces - Understand dependencies - Note edge cases and boundaries ### 2. Detect test framework Check for: - `jest.config.js` → Jest - `vitest.config.ts` → Vitest - `pytest.ini` → pytest - `mocha` in package.json → Mocha ### 3. Generate tests Follow the detected framework conventions. ## Test categories ### Happy path Normal expected behavior with valid input. ### Edge cases - Empty inputs - Null/undefined values - Boundary values (0, -1, MAX_INT) - Single item vs multiple items ### Error cases - Invalid input types - Missing required parameters - Network/IO failures - Timeout scenarios ### Integration points - Database interactions - External API calls - File system operations ## Output format ```typescript describe('[ComponentName]', () => { describe('[methodName]', () => { // Happy path it('should [expected behavior] when [condition]', () => { // Arrange // Act // Assert }); // Edge cases it('should handle empty input', () => {}); it('should handle null values', () => {}); // Error cases it('should throw when [invalid condition]', () => {}); }); }); ``` ## Conventions - One assertion per test (when practical) - Descriptive test names - AAA pattern (Arrange-Act-Assert) - No test interdependence - Mock external dependencies ## Usage ``` /generate-tests src/utils/calculator.ts /generate-tests src/services/ ``` $ARGUMENTS
