Why must the test fail first?

Failing first proves that the test is testing something new and that it isn't passing by accident or due to existing logic, ensuring the test is valid.

What is the TDD Red Phase?

The Red phase is the first step in Test-Driven Development where you write a test that fails before writing any implementation code to define the expected behavior of a new feature.

What is the AAA pattern mentioned in the skill?

AAA stands for Arrange, Act, and Assert. It is a standard pattern for organizing tests: Arrange (set up data), Act (call the function), and Assert (verify the result).

Which programming languages are supported?

The skill provides specific file naming patterns and structures for Go (*_test.go), Python (test_*.py), TypeScript (*.test.ts), and Rust (tests/*.rs).

How does this skill help with TDD?

It provides domain-specific guidance on test design, enforces naming conventions, and uses a lifecycle script to ensure you have a verified failing test before moving to implementation.

安全与测试

Automates the initial Red phase of Test-Driven Development by guiding the creation of failing test cases before implementation.

关于

The TDD Red Phase skill is designed to instill discipline in the Test-Driven Development workflow by guiding developers through the critical first step of writing failing tests. It provides standardized templates for the Arrange-Act-Assert (AAA) pattern, enforces descriptive naming conventions, and supports language-specific file structures for Go, Python, TypeScript, and Rust. By integrating with a workflow orchestration script, it ensures that implementation code is only written after a valid failure is confirmed, leading to better-designed features and higher test coverage.
