Can it help me reach 100% test coverage?

While it focuses on critical paths and edge cases to significantly boost coverage, its primary goal is high-quality, meaningful tests rather than just hitting a numerical target.

Which testing frameworks are supported?

The Test Writer Agent supports all major mainstream frameworks including JUnit for Java, pytest for Python, and Jest for JavaScript/TypeScript, among others.

How does it structure the generated test code?

It follows the industry-standard AAA (Arrange-Act-Assert) pattern, ensuring that every test is readable, maintainable, and focuses on a single point of failure.

Does this skill handle external API or database dependencies?

Yes, it specifically includes functionality for Mocking and Stubbing to isolate code units and verify interactions with APIs and databases without requiring a live environment.
