avoiding-testing-anti-patterns

What problem does it solve?

This Skill helps developers avoid common pitfalls in software testing that lead to brittle, misleading, or ineffective tests, ensuring tests accurately reflect and verify real application behavior.

Core Features & Use Cases

• Prevent Mock Misuse: Guides against testing mock behavior or over-mocking dependencies.
• Ensure Test Completeness: Promotes testing all states (happy path, error, empty) and user-visible behavior, not implementation details.
• Improve Test Robustness: Helps write tests that are resilient to refactoring and accurately catch bugs.
• Use Case: When writing a new test for a UI component, this Skill ensures you're testing what the user sees and interacts with, rather than internal component state or props, making your tests more stable.

Quick Start

Use the avoiding-testing-anti-patterns skill to review a test you are writing to ensure it is not testing mock behavior.
