How do I trigger the test generation?

You can trigger the skill by asking Claude to 'generate tests' for a file or by using the shortcut command 'gut' followed by the file path.

Which testing frameworks are supported?

The skill supports a wide range of popular frameworks including Jest, pytest, JUnit, and others, with the ability to auto-detect or accept manual specification.

Can I use this for specific functions only?

Yes, the skill can analyze and generate test cases for specific functions, classes, or entire modules depending on your request.

Does it handle external dependencies?

Yes, the skill automatically identifies external dependencies and generates the necessary mocks and stubs to ensure unit tests remain isolated and fast.

Does it replace the need for manual code review?

While it generates highly accurate tests, we recommend reviewing and refining the output to ensure it aligns perfectly with your specific business logic and requirements.

Security & Testing

Generates comprehensive, framework-specific unit tests and mocks to ensure code quality and maximize test coverage automatically.

About

The Unit Test Generator skill empowers developers to rapidly build robust testing suites by analyzing source code and identifying key logical paths. It intelligently detects your project's testing framework—such as Jest, pytest, or JUnit—and constructs detailed test cases that cover happy paths, edge cases, and error conditions. By automatically creating mocks for external dependencies and providing a quick 'gut' shortcut, this skill significantly reduces the manual overhead of maintaining high code quality and prevents regressions in complex environments.
