Engineering Testing in PHP

Engineering testing in a PHP context refers to the practice of integrating comprehensive testing strategies directly into the development process. In these roles, developers are responsible for writing and maintaining automated tests to ensure code quality, prevent regressions, and validate functionality from the smallest unit to the entire application.

Types of Testing in PHP Development

PHP developers employ a multi-layered testing approach to build robust software. This includes writing unit tests with frameworks like PHPUnit or Pest to verify individual components, integration tests to ensure different parts of the application work together correctly, and end-to-end (E2E) tests to simulate real user workflows using tools like Codeception or Laravel Dusk.

Key Skills and Tooling

A strong focus on engineering testing requires proficiency with specific tools and methodologies. Important skills for developers include:

• Expertise in testing frameworks such as PHPUnit, Pest, or Codeception.
• Understanding of Test-Driven Development (TDD) and Behavior-Driven Development (BDD).
• Ability to create mock objects, stubs, and fakes for isolated testing.
• Experience with configuring and running tests within a CI/CD pipeline.
• Familiarity with static analysis tools like PHPStan or Psalm to catch errors before runtime.
