Enforces high-quality testing standards by preventing mock-behavior testing and production code pollution.
This skill acts as a specialized guardrail for developers to ensure test suites are resilient, meaningful, and maintainable. It identifies and prevents critical testing mistakes, such as asserting on mock existence rather than real behavior, polluting production classes with test-specific methods, and creating incomplete mocks that lead to integration failures. By utilizing structured 'Gate Functions' and enforcing strict TDD principles, this skill helps developers write tests that verify actual logic while maintaining a clean separation between production code and test utilities.
