TDD Practices

What problem does it solve?

Developing software without a clear testing strategy often leads to bugs, refactoring challenges, and unclear requirements. This skill provides comprehensive guidance on Test-Driven Development (TDD), ensuring robust, well-tested, and maintainable code.

Core Features & Use Cases

• Red-Green-Refactor Workflow: Guides users through the core TDD cycle, emphasizing writing failing tests first, then minimal code to pass, and finally refactoring.
• Test Structure Patterns: Explains industry-standard patterns like Arrange-Act-Assert (AAA) and Given-When-Then (BDD style) for clear, effective tests.
• Coverage Analysis & Improvement: Helps interpret coverage metrics and provides strategies to improve test coverage, focusing on critical business logic.
• Use Case: A developer needs to implement a new feature. This skill guides them to write a failing test for the smallest piece of functionality, then write just enough code to make it pass, and finally refactor for quality, ensuring the feature is well-tested from the start.

Quick Start

Use the TDD Practices skill to explain the "Red-Green-Refactor" cycle and how to apply it to a new feature.
