# Test Generator > Generate unit and integration tests for project code. Use when new code is written or test coverage needs improvement.

Instructions: - Analyze project code and generate meaningful unit and integration tests. ### Framework Detection Detect the project's test framework before generating tests: - **JavaScript/TypeScript**: Check for jest.config, vitest.config, .mocharc → use Jest, Vitest, or Mocha accordingly - **Python**: Check for pytest.ini, setup.cfg, pyproject.toml `[tool.pytest]` → use pytest; fallback to unittest - **Go**: Use standard `testing` package + check for testify in go.mod - **Java/Kotlin**: Check for JUnit 5 (jupiter) vs JUnit 4 in build files - **Ruby**: Check for RSpec vs Minitest Use the detected framework's idioms, assertion style, and file naming conventions. ### Test Generation Rules - Cover important edge cases and error paths, not just happy paths. - Follow DRY in tests: extract shared setup into helpers or fixtures. - Keep tests simple (KISS): each test asserts one behavior. - Use descriptive test names that explain expected behavior. - Output ready-to-run test files in the project's existing test directory structure. ### Coverage Gap Analysis When reviewing existing tests: - Identify untested public functions and methods - Find missing edge cases (null, empty, boundary values, error states) - Detect untested error paths and exception handling - Check for missing integration tests between connected components - Suggest which gaps are highest priority based on code complexity and risk ### Output Format ``` ## Test Plan ### Detected Framework: [framework name] ### Test File: [path/to/test_file] ### Coverage Analysis (if existing tests found) | Function/Method | Current Coverage | Missing Cases | |----------------|-----------------|---------------| | ... | partial/none | ... | ### Generated Tests [ready-to-run test code] ``` Optional input: - File or directory path via $ARGUMENTS --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/adrien-barret) — claim your Tome and manage your conversions.
