Unit Testing with PHPUnit

• A solid foundation in PHP coding
• Experience with testing is helpful, but not required

Audience

• Intermediate to advanced PHP developers who want to improve the testability of their code

PHPUnit is a unit testing framework for PHP. PHPUnit employs strict parameters to determine whether individual units of code are bug-free and ready for deployment. By isolating and testing individual units, developers can ensure greater application stability, avoid regression bugs, and reduce the costs associated with malfunctioning code in production.

This instructor-led, live training teaches participants how to write testable code in the form of testing units to facilitate the diagnosis, isolation, and resolution of bugs. The training walks participants through the creation of a work-ready, testing environment using the PHPUnit testing framework.

By the end of this training, participants will be able to:

• Distinguish between good and bad testing units.
• Read and interpret test results.
• Proactively manage and diagnose their code base to reduce bugs.
• Ensure that their code base is fit for continuous integration and deployment.

Format of the course

• Part lecture, part discussion, exercises and heavy hands-on practice

Day 1: Introduction to Unit Testing and PHPUnit

1. Introduction to Software Testing

• The importance of tests in the software lifecycle
• Overview of test types: unit, integration, system

2. Basics of Unit Testing

• Definition and objectives of unit testing
• Advantages of introducing unit tests to a project

3. Introduction to PHPUnit

• Installation and configuration of the environment
• Structure of a unit test: setup, test cases, teardown
• Basic assertions and annotations in PHPUnit

4. First Steps in Writing Tests

• Creating simple tests for functions and methods
• Organizing tests: grouping, dependencies, excluding tests

5. Practice: Creating Tests for a Sample Application

• Practical exercises: writing tests for an existing class
• Analyzing test results, dealing with errors

Day 2: Advanced Techniques and Best Practices

6. Testing Behaviors with Mock Objects

• Introduction to mocking and stubbing
• Examples of using mocks in PHPUnit to simulate dependencies

7. Advanced Assertions and Annotations

• Assertions concerning exceptions, arrays, objects
• Using data providers for parameterized tests

8. Test Driven Development (TDD) with PHPUnit

• Red-Green-Refactor cycle: from theory to practice
• Practical example of TDD application in a project

9. Best Practices in Unit Testing

• Test coverage: how to measure and interpret
• Organization and maintenance of a unit test suite

10. Tools and Extensions Supporting PHPUnit

• Overview of useful tools and libraries
• Test automation: integration with CI/CD systems

11. Summary and Discussion

• Discussion of the biggest challenges and common mistakes
• Answers to questions, sharing participants' experiences

This training plan is designed to ensure participants have a solid foundation in unit testing and practical skills in using PHPUnit. The balance between theory and practice allows for a better understanding of the material and application of learning in real projects.
