Does it automatically identify dependencies?

Yes, the skill performs a dependency analysis on the target code to identify external imports and services that need to be replaced with test doubles.

What testing frameworks are supported by this skill?

The skill natively supports popular frameworks like Jest and Sinon, but it can generate test doubles for most JavaScript/TypeScript testing libraries when specified.

Can I choose between a mock and a stub?

Absolutely. You can specify the type of test double you need based on whether you want to verify behavior (mocks), provide controlled responses (stubs), or track interactions (spies).

How do I trigger the generation process?

You can trigger the skill by using the /gen-doubles or /gd command, or by asking Claude to 'generate mocks' for a specific file or function.

Security & Testing

Generates mocks, stubs, spies, and fakes automatically to streamline unit testing and dependency isolation across various testing frameworks.

The Automated Test Doubles Generator skill simplifies the complex process of unit testing by identifying code dependencies and automatically creating appropriate test doubles. By supporting popular frameworks like Jest and Sinon, it allows developers to quickly isolate units of code without the manual overhead of writing mock objects. Whether you need to simulate API responses, control service behaviors with stubs, or track function calls with spies, this skill provides production-ready code snippets that integrate directly into your test suite via simple CLI commands like /gen-doubles.
