Unit & Integration Testing

关于

This skill serves as a comprehensive guide for developers looking to improve the quality and reliability of their test suites across unit, integration, component, and API layers. It enforces critical rules such as a 10-statement limit per test and the 'Smoking Gun' principle to ensure clear cause-and-effect relationships in assertions. By providing detailed implementation patterns for data factories, mocking external collaborators, and testing complex DOM interactions using accessible locators, the skill helps create resilient test suites that focus on user behavior rather than implementation details.

主要功能

• Enforcement of the AAA (Arrange-Act-Assert) pattern with strict statement limits for maximum readability.
• Comprehensive mocking strategies that isolate external collaborators while maintaining internal system integrity.
• Standardized data factory patterns using Faker for generating typed, realistic domain data.
• 0 GitHub stars
• Guidelines for the Smoking Gun and Breadcrumb principles to ensure clear, self-contained test logic.
• User-centric DOM testing practices focusing on accessible roles and auto-retriable assertions.

使用场景

• Refactoring bloated or brittle test suites to follow cleaner, more maintainable architectural patterns.
• Conducting code reviews to identify and correct common testing anti-patterns and logic violations.
• Establishing a robust testing strategy for new microservices, APIs, or frontend components.
