Test-Driven Development (TDD) Workflow FAQs

Question 1

Can I use this skill for refactoring existing code?

Accepted Answer

Absolutely. The skill includes a specific 'Refactor' phase that focuses on improving code quality, applying SOLID principles, and enhancing type safety while ensuring all existing tests pass.

Question 2

How does the TDD skill track development progress?

Accepted Answer

The skill uses a structured phase system (Red, Green, Refactor, Verify) tracked through the TodoWrite format. This ensures that a failing test is always written before code implementation begins.

Question 3

When should I avoid using the TDD skill?

Accepted Answer

TDD is best for logic-heavy features. It is generally not recommended for exploratory coding, rapid UI prototyping, static configurations, or trivial 'glue' code where the overhead may exceed the benefits.

Question 4

Does it support advanced testing methodologies like mutation testing?

Accepted Answer

Yes, it specifically encourages the use of Stryker for TypeScript and Tarpaulin for Rust to verify that your tests are actually effective at catching potential bugs.

Question 5

Which programming languages and tools are supported?

Accepted Answer

While the TDD methodology is universal, this skill provides specialized patterns and commands for TypeScript (using the Bun runtime) and Rust (using Cargo and Tarpaulin).
