Creating Feature Tests

Feature tests generated by this Skill follow a fail-first, red-green-refactor TDD approach. The Skill creates minimal failing tests for user-facing behaviors like authentication, form submission, and navigation, then you implement code to make them pass, ensuring behavior is correctly covered.

Yes. This Skill applies across languages and frameworks to automate behavior-driven feature test creation. It handles dependency mocking, test scaffolding, and inline documentation, adapting to your tech stack rather than requiring a specific platform.

Behavior-driven test generation automates extraction of user-facing behaviors, scaffolds mocks for external services and databases, creates fail-first tests with edge case coverage, and produces documented test code—eliminating manual test writing and reducing missed edge cases.

Provide the user flows you need tested—authentication, form submission, navigation—and the Skill generates feature tests with mocked dependencies, minimal failing tests, and coverage for valid and invalid cases, accelerating TDD workflow without manual test scaffolding.

Use BDD feature tests when testing primary user flows and critical behaviors end-to-end. Feature tests validate what users actually experience—login, registration, checkout—whereas unit tests verify isolated components. This Skill targets user-facing behavior gaps, especially when BDD or feature test coverage is insufficient.
