What happens if coverage falls below 80%?

The skill identifies this as a violation of core principles, prompting the developer to add necessary tests to meet the mandatory coverage requirement.

How does this skill handle test evidence?

The skill requires capturing and formatting actual command-line output from test runners, including pass/fail status and specific coverage percentages.

Can I use this for existing codebases?

Yes, while it encourages test-first development, it can be used to ensure any new changes or refactors in existing codebases meet the 80% coverage threshold.

What testing frameworks does this skill support?

It specifically supports Pytest for Python backends and NPM-based test runners (such as Jest or Vitest) for TypeScript frontends, utilizing BDD-style syntax.

Security & Testing

Enforces a strict test-driven development workflow with BDD syntax and mandatory coverage requirements for reliable code.

The Mandatory TDD/BDD Testing skill ensures code quality and reliability by enforcing a rigorous test-first approach across both Python backend and TypeScript frontend environments. It mandates the use of BDD-style syntax, deterministic selectors, and a minimum of 80% code coverage to prevent regressions and maintain high developer confidence. This skill is ideal for teams building critical infrastructure like E-commerce APIs, where automated verification and execution evidence are required before any code reaches production.
