Enforces a flat, mock-minimal unit testing architecture for Vitest and Jest in TypeScript projects.
This skill provides a comprehensive set of rules and best practices for TypeScript unit testing, emphasizing a flat structure without nested describe blocks to improve readability and maintainability. It guides developers in implementing behavior-driven tests, minimizing mocks to favor real implementation reliability, and utilizing parameterized tests for robust edge-case coverage. By following the integrated test pyramid guidelines and standardized file naming conventions, teams can ensure a high-quality, consistent testing suite that is easy to navigate and scale across large-scale applications.
Key Features
01Support for parameterized testing using test.each patterns
02Test pyramid enforcement for optimal balance between unit, integration, and E2E tests
03Flat test structure implementation to eliminate complex describe block nesting
04Standardized file naming conventions (e.g., .validation.test.ts) for group-less organization
050 GitHub stars
06Minimal mocking guidelines to prioritize testing real-world behavior
Use Cases
01Refactoring legacy test suites into a more readable flat architecture
02Standardizing unit testing patterns across a distributed development team
03Onboarding developers to a project's specific Vitest or Jest naming and structure conventions
