Does this skill support mocking modules?

Absolutely. This skill covers Bun's powerful 'mock.module()' functionality, allowing you to easily mock external dependencies and internal modules.

Why use Bun for testing instead of Vitest or Jest?

Bun is built in Zig and features an integrated runtime, which eliminates the transpilation overhead for TypeScript and results in significantly faster test execution times.

Is Bun's test runner compatible with Jest?

Yes, Bun provides a built-in test runner that is largely compatible with Jest's API, including matchers like expect, describe, and test, making migration straightforward.

How do I run tests with coverage in Bun?

You can generate coverage reports by running 'bun test --coverage', which is a native feature of the Bun runtime requiring no additional plugins.

Can I perform snapshot testing with Bun?

Yes, Bun supports snapshot testing natively via the 'expect(value).toMatchSnapshot()' matcher, helping you catch unexpected UI or data structure changes.

安全与测试

Implements high-performance unit and integration tests using Bun's built-in, Jest-compatible test runner.

关于

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.
