Can I use this for integration testing?

Yes, the skill is capable of generating Unit, Integration, Contract, and Property-based tests depending on your requirements.

Why focus on failing tests specifically?

In Test-Driven Development, the 'Red' phase involves writing a failing test first to verify that the test is valid and that the expected behavior does not yet exist, preventing false positives.

Does this skill work with production databases?

No, for safety reasons, this skill is designed to use isolated fixtures and mock dependencies, avoiding production environments and flaky external dependencies.

How does the skill handle edge cases?

It identifies specific edge case categories such as null/empty values, boundary limits, special characters (Unicode), and invalid state transitions to ensure robust coverage.

What testing frameworks are supported by this skill?

The skill supports a wide range of popular frameworks including Jest/Vitest for JavaScript/TypeScript, pytest for Python, Go's native testing package, and RSpec for Ruby.

Security & Testing

Generates comprehensive failing tests to define expected software behavior and edge cases during the initial TDD phase.

This skill automates the critical 'Red' phase of Test-Driven Development (TDD) by generating robust, framework-specific failing tests that capture intended behavior, business constraints, and edge cases. By utilizing a specialized test-automator agent, it ensures that tests fail for the right reasons—missing implementation rather than setup or syntax errors—providing a clear roadmap for the subsequent development of production code across multiple languages including JavaScript, Python, Go, and Ruby.
