Does it support data-driven testing?

Absolutely. It includes patterns for parameterized tests using test.each to run the same test logic against multiple data sets efficiently.

Is this skill specific to the Jest framework?

Yes, this skill is specifically optimized for Jest, providing patterns for its built-in mocking, spying, and assertion libraries.

How does this skill handle asynchronous testing?

It provides dedicated patterns for async/await testing, handling promise rejections, and utilizing fake timers for time-dependent logic.

Can it help me identify poor testing habits?

Yes, the skill includes a section on anti-patterns to help you avoid testing internal implementation details and focus on behavioral outcomes.

セキュリティとテスト

Implements robust unit testing patterns, mocking strategies, and best practices for JavaScript and Node.js using Jest.

This skill provides Claude with a comprehensive framework for generating high-quality unit tests in JavaScript and Node.js environments. It leverages the AAA (Arrange-Act-Assert) pattern to ensure test clarity and covers advanced scenarios including module mocking, partial spying with spyOn, and handling complex asynchronous operations. By providing standardized templates for describe-block organization and parameterized tests, it helps developers build maintainable, high-coverage test suites while avoiding common anti-patterns like testing implementation details over behavior.
