PHPUnit Fundamentals: Automated Unit Testing for PHP

Manual testing by refreshing a browser or using print statements is slow, repetitive, and prone to human error. Automated unit testing allows you to verify your logic instantly and ensures that new features do not accidentally break existing functionality. This course guides you through the professional process of writing clean, automated tests for your PHP applications. You will transition from manual debugging to a modern workflow where code quality is verified by a robust test suite, making your development process faster and more predictable. What you'll learn: - Understand the core principles of unit testing and how to structure testable PHP code. - Configure PHPUnit and write test cases for functions, classes, and complex logic. - Apply dependency injection and use test doubles, such as mocks and stubs, to isolate components. - Practice Test-Driven Development (TDD) to design better software architecture from the start. - Handle advanced scenarios including testing protected methods, abstract classes, and exceptions. - Implement modern PHP features such as attributes and strict type hinting within your test suite. The course begins with foundational definitions and the philosophy of automated testing before moving into the practical syntax of the PHPUnit framework. You will progress through written explanations of the API, learning how to decouple code and manage dependencies effectively through clear, text-based examples. This course is designed for PHP developers who are new to automated testing. No prior experience with PHPUnit or testing frameworks is required. Start building more reliable PHP applications through the power of systematic unit testing.
