About This Skill
What it does
This skill enables AI agents to write, test, and debug JavaScript and TypeScript code using Jest, a popular testing framework. It supports creating unit tests, mocking functions, and asserting expected outcomes for both frontend and backend applications.
When to use it
- You need to implement automated tests for a JavaScript or TypeScript project.
- You want to verify the correctness of functions, components, or APIs in your codebase.
- You are debugging an application and require test-driven development practices.
Key capabilities
- Writing unit tests with Jest syntax
- Mocking dependencies and functions
- Asserting values using Jest matchers
- Running test suites and reporting results
Example prompts
- "Write a Jest test for this function that checks if it returns the correct value."
- "Mock the API call in this component and write tests for the success and error cases."
- "Generate a test suite for this TypeScript class with edge case coverage."
Tips & gotchas
- Ensure your project has Jest installed as a development dependency.
- Some advanced mocking features may require additional configuration or plugins.
