What is the recommended mocking strategy?

The skill advises a 'minimal mock' approach. Mocks are discouraged for internal functions and utilities but permitted for external dependencies like HTTP requests, databases, and time-dependent logic.

Does this skill work with both Jest and Vitest?

Yes, the conventions and rules provided by this skill are designed to be compatible with both the Vitest and Jest testing frameworks.

How does the skill handle test file organization?

It supports both colocation (placing tests next to the source code) and dedicated __tests__ directories, provided they follow the category-based file naming convention.

Why does this skill discourage the use of describe blocks?

It promotes a 'Flat Principle' where grouping is achieved through file splitting and clear naming conventions rather than deep nesting, which improves readability and simplifies test execution.

安全与测试

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.

主要功能

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
