Atelier Typescript Testing

What it does

This skill enables AI agents to write and execute Jest tests for TypeScript code. It can generate test files, create individual test cases, and automatically run the tests to verify functionality. The skill aims to improve code quality and ensure proper behavior of TypeScript projects through automated testing.

When to use it

• Automated Testing: Generate unit tests for existing TypeScript functions or components.
• Regression Prevention: Create tests before refactoring code to guarantee no new issues are introduced.
• Code Quality Assurance: Ensure newly written TypeScript code adheres to expected behavior and edge cases.
• Learning & Education: Generate test examples to understand how to write effective Jest tests for TypeScript.

Key capabilities

• Generates Jest testing framework files.
• Creates individual test case functions within a test file.
• Executes generated tests.
• Supports TypeScript code.

Example prompts

• "Write Jest tests for this function: function add(a, b) { return a + b; }"
• "Generate a test file for the component ./src/components/MyComponent.tsx."
• “Create a test case to verify that add(2, 3) returns 5.”

Tips & gotchas

This skill requires a basic understanding of Jest and TypeScript syntax to interpret and potentially modify the generated tests effectively. The quality of the generated tests depends on the clarity and completeness of the provided code or component description.
