How do I trigger the test double generation?

You can use the slash commands /gen-doubles or /gd, or simply ask Claude in natural language to generate mocks for a specific file or function.

Does it support complex dependency trees?

Yes, the skill performs a dependency analysis on the provided code to identify all external imports and services that require isolation for a unit test.

Which testing frameworks are supported?

The skill primarily supports popular frameworks like Jest and Sinon, but it can adapt to other JavaScript and TypeScript testing libraries based on your code context.

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

The skill follows testing best practices: it creates mocks for behavior verification, stubs for providing specific return values, and spies for tracking how functions are called.

安全与测试

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

This skill automates the creation of test doubles, including mocks, stubs, spies, and fakes, to isolate code units during testing. By analyzing your source code's dependencies, it identifies external calls and service interactions, then produces framework-specific code for Jest, Sinon, and others. It is an essential tool for developers looking to accelerate their unit testing workflow and ensure robust code coverage without the manual overhead of writing complex mock objects.
