SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps developers build robust, regression-safe Symfony applications by integrating Test-Driven Development (TDD) principles with PHPUnit, ensuring code quality and reliability.

Core Features & Use Cases

TDD Workflow: Guides you through the RED-GREEN-REFACTOR cycle for Symfony development.
Regression Protection: Ensures new changes don't break existing functionality.
Bug Conversion: Facilitates turning bug reports into executable, failing tests.
Use Case: When developing a new feature in your Symfony application, use this skill to write a failing test first, then implement the code to pass, and finally refactor while maintaining a green test suite.

Quick Start

Use the symfony:tdd-with-phpunit skill to drive the development of a new Symfony feature using the RED-GREEN-REFACTOR cycle.

FAQPage Schema

How do I use TDD with PHPUnit in Symfony to develop new features?▼

TDD with PHPUnit in Symfony guides you through the RED-GREEN-REFACTOR cycle: write a failing test, implement minimal code to pass it, then refactor while keeping the test suite green for regression-safe behavior.

How can I convert a Symfony bug report into an executable test?▼

You can convert a Symfony bug report into an executable test by writing a failing PHPUnit test that reproduces the reported behavior. This TDD approach ensures the bug is fixed and prevents future regressions when the test passes.

What is the RED-GREEN-REFACTOR cycle for Symfony application development?▼

The RED-GREEN-REFACTOR cycle for Symfony application development involves writing a failing test, implementing minimal code to make it pass, and refactoring the code while preserving a green test suite. PHPUnit provides deterministic testing throughout this process.

Can I use this TDD approach to refactor existing Symfony code safely?▼

Yes, using TDD with PHPUnit for Symfony allows you to refactor existing code safely. You must maintain a green test suite throughout the refactoring process, which provides strong regression protection and ensures new changes do not break existing functionality.

Does Symfony TDD with PHPUnit require specific dependencies or environment setup?▼

Symfony TDD with PHPUnit does not list specific external dependencies. It requires adherence to TDD principles and a Symfony environment configured for PHPUnit testing to execute deterministic tests and drive application delivery.
