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

The skill generates mocks for behavior verification and expectations, whereas stubs are generated to provide canned answers to calls made during the test.

Which testing frameworks does this skill support?

The skill supports popular JavaScript and TypeScript testing frameworks such as Jest and Sinon, and can be adapted for other environments through natural language requests.

Does it modify my source code directly?

It provides the generated test double code as snippets or file updates that you can review and integrate into your test files.

Can the skill automatically detect dependencies?

Yes, it analyzes the code under test to identify external functions, classes, and modules that should be replaced with test doubles for isolation.

How do I trigger the generation of mocks or stubs?

You can use the dedicated commands /gen-doubles or /gd, or simply ask Claude to 'generate mocks for this file' in natural language.

Seguridad y Pruebas

Generates automated mocks, stubs, and spies to isolate code for comprehensive unit testing across various frameworks.

The Test Double Generator skill empowers developers to streamline their unit testing workflow by automatically creating mocks, stubs, spies, and fakes. By performing deep dependency analysis on your source code, the skill identifies external services and API calls that need isolation, then generates framework-specific code for libraries like Jest or Sinon. This automation significantly reduces the manual boilerplate required for robust testing, ensuring that unit tests remain fast, reliable, and decoupled from external side effects.
