How does it handle complex mocking scenarios?

For advanced testing needs, TDD Companion integrates with and can defer to the 'superpowers:test-driven-development' skill for deeper methodology.

What is the 'Green' phase rule?

It enforces writing the absolute minimum code necessary to make the current test pass, discouraging premature optimization or adding unrelated features.

Does this skill work with Drupal-specific tests?

Yes, it includes specialized support and templates for Drupal Unit, Kernel, and Functional tests using DDEV and PHPUnit commands.

What happens if I try to write code before a test?

The TDD Companion will intervene and stop the implementation process, requiring you to write and run a failing test first to satisfy the 'Red' phase of the cycle.

When is this skill automatically activated?

It triggers during Phase 3 implementation, specifically when code changes are discussed or after a task context has been loaded.

Security & Testing

Enforces a strict Red-Green-Refactor workflow to ensure all code is covered by tests before implementation begins.

TDD Companion is a specialized Claude Code skill designed to maintain high code quality through rigorous Test-Driven Development (TDD) practices. Specifically optimized for Drupal environments, it acts as a procedural guardrail that prevents implementation code from being written until a failing test is established. It guides users through the Red-Green-Refactor cycle, provides Drupal-specific test templates for Unit, Kernel, and Functional tests, and ensures that only the minimum necessary code is written to satisfy requirements, effectively preventing feature creep and technical debt.
