Unit Testing with PHPUnit Training in Dublin, Ireland

Unit testing with PHPUnit training focuses on equipping participants with the skills to write and execute unit tests for PHP applications using the PHPUnit testing framework. The course covers essential topics such as setting up PHPUnit, creating test cases, and understanding assertions to validate expected outcomes. Participants learn to write testable code, organize tests in suites, and use mock objects and stubs to isolate components during testing. Hands-on exercises allow participants to practice writing unit tests, debugging failing tests, and integrating PHPUnit with CI/CD pipelines. By the end of the training, attendees gain the expertise to implement reliable, automated unit tests that enhance the maintainability and quality of PHP code.

Introduction to Unit Testing and Writing PHPUnit Tests

• Introduction to Unit Testing

• What is unit testing and why is it important in PHP development?

• The role of unit testing in software quality assurance.

• Overview of PHPUnit framework.

• Benefits of unit testing: catching bugs early, simplifying refactoring, ensuring code quality.

• Setting Up PHPUnit for PHP Projects

• Installing PHPUnit and setting up the development environment.

• Configuring PHPUnit for a PHP project (composer installation, configuration file).

• Understanding PHPUnit’s directory structure and test organization.

• Writing Your First PHPUnit Test

• Creating a basic test class using PHPUnit\Framework\TestCase.

• Writing the first test method with assertions: assertEquals(), assertTrue(), assertFalse().

• Running PHPUnit tests from the command line.

• Understanding PHPUnit output: passed, failed, skipped tests.

• Assertions in PHPUnit

• Different types of assertions in PHPUnit (e.g., assertEquals(), assertContains(), assertNull(), assertCount()).

• Using assertions to validate code functionality and expected results.

• Hands-On Exercise

• Test Lifecycle: Setup and Teardown

• Understanding the setup and teardown methods (setUp() and tearDown()).

• Using setUpBeforeClass() and tearDownAfterClass() for class-level setup.

• Hands-On Exercise

• Summary and Q&A

• Recap of key concepts.

• Open Q&A session to address any doubts or questions.

Advanced Testing Techniques and Mocking

• Test-Driven Development (TDD) with PHPUnit

• Introduction to Test-Driven Development (TDD) and its benefits.

• Writing tests before code: red-green-refactor cycle.

• Hands-On Exercise

• Mocking in PHPUnit

• The concept of mocking and why it's important in unit testing.

• Introduction to PHPUnit’s mock objects: createMock() and getMockBuilder().

• Mocking external services and dependencies for isolated testing.

• Hands-On Exercise

• Testing for Edge Cases and Exception Handling

• Writing tests to handle edge cases (e.g., invalid input, boundary conditions).

• Using expectException() to test exceptions.

• Validating exception handling and error messages in PHP code.

• Hands-On Exercise

• Running PHPUnit Tests and Integrating with CI/CD

• Running PHPUnit tests from the command line and generating reports.

• Integrating PHPUnit with Continuous Integration (CI) tools like Jenkins or GitLab CI.

• Generating test coverage reports using PHPUnit and tools like Xdebug.

• Hands-On Exercise

• Best Practices for PHPUnit Testing

• Writing maintainable and readable tests.

• Organizing tests in multiple files and directories.

• Writing tests that are independent, fast, and isolated.

• Hands-On Exercise

• Final Project: Implementing Unit Testing for a PHP Application

• Applying all learned concepts in a final project: writing comprehensive tests for a PHP application.

• Writing tests using assertions, TDD, and mocking.

• Reviewing and refining test coverage.

• Course Summary and Q&A

• Recap of key concepts learned throughout the course.

• Final Q&A session to address any remaining questions.
