Implements high-performance unit and integration tests using Bun's built-in, Jest-compatible test runner.
The Bun Testing skill enables Claude to write, organize, and execute tests using Bun's native testing infrastructure, which is significantly faster than traditional runners like Jest. It provides comprehensive patterns for test structure using describe and test blocks, Jest-compatible assertions, and sophisticated mocking for both functions and modules. By utilizing this skill, developers can ensure their JavaScript and TypeScript applications are robust, leveraging Bun's fast execution, built-in coverage reporting, and native snapshot testing capabilities to maintain high code quality with minimal overhead.
