Does it work with existing codebases?

Yes, it analyzes your existing source files to identify dependencies and creates contextually accurate test doubles that match your current code structure.

Can it handle external API dependencies?

Absolutely. It is designed to identify calls to external services and create mocks that simulate those responses to keep your tests isolated and fast.

What is the difference between the mocks and stubs it generates?

Mocks are generated for behavior verification, while stubs provide canned answers to calls made during the test. The skill chooses the best type based on your specific request.

Which testing frameworks are supported?

The skill primarily supports popular frameworks like Jest and Sinon, but it can generate test doubles for others if you specify the framework in your request.

How do I trigger the test double generation?

You can use the slash commands `/gen-doubles` or `/gd`, or simply ask Claude to generate a mock or stub for a specific file or function.

Generates automated mocks, stubs, spies, and fakes for unit testing by analyzing code dependencies and framework requirements.

The Test Doubles Generator skill streamlines the unit testing process by automatically creating the necessary isolation objects for your code. By performing deep dependency analysis on your source files, it identifies which external services or internal modules need to be replaced and generates framework-specific mocks, stubs, or spies for libraries like Jest and Sinon. This automation significantly reduces the manual effort required to set up complex test environments, ensuring your unit tests remain isolated, fast, and reliable while improving overall code coverage.
