What are Test Builders?

Test Builders are a fluent pattern suggested by this skill to simplify tedious test setups, making your test code more readable and easier to maintain.

Can it handle non-deterministic logic like time?

Yes, it provides patterns for extracting Clock and RandomGenerator interfaces so you can 'freeze' time or control random outputs during your test suite.

Does it support modern PHP frameworks?

Absolutely. The architectural principles (SOLID, Clean Architecture, PSR) apply to Laravel, Symfony, and custom PHP applications alike.

How does this skill help with legacy PHP code?

It identifies hardcoded 'new' keywords and global state, suggesting step-by-step refactoring to move toward interfaces and dependency injection, making the code instantly mockable.

Security & Testing

Analyzes PHP code to provide actionable refactoring suggestions that improve unit testability and architectural modularity.

This skill empowers developers to transform tightly coupled PHP code into highly testable, modular systems. By identifying anti-patterns like hardcoded dependencies, non-deterministic logic, and mixed I/O operations, it provides concrete code examples for implementing Dependency Injection, Interface Extraction, and the Repository pattern. It is an essential tool for teams adopting Test-Driven Development (TDD) or refactoring legacy applications into Clean Architecture or DDD patterns, ensuring code can be easily mocked and verified.
