Does this skill support asynchronous testing?

Yes, it includes specific patterns for async/await, promise resolutions, and handling custom timeouts within Vitest.

What is the core principle of this testing skill?

The core principle is to test behavior rather than implementation, ensuring that tests verify what the code does rather than how it does it, which makes tests more resilient to refactoring.

Can I use these patterns with other frameworks like Jest?

While the syntax and examples are tailored for Vitest, the high-level patterns like AAA, BDD, and test isolation are industry standards applicable to Jest and most modern JS testing libraries.

How does the skill handle test data?

It promotes the use of Factory and Builder patterns to create consistent, maintainable test data objects without repetitive setup code.

Security & Testing

Implements professional unit testing patterns and best practices for TypeScript projects using the Vitest framework.

About

This skill provides a comprehensive framework for writing high-quality unit tests in TypeScript. It guides the AI to follow industry-standard patterns like Arrange-Act-Assert (AAA), implement robust test data factories, and organize test files effectively. By focusing on behavior rather than implementation, it ensures tests are resilient to refactoring while covering edge cases, asynchronous logic, and error handling with clear, maintainable code structures. It is an essential tool for developers looking to increase code coverage and maintain software reliability.
