 PHPUnit Fundamentals: A TDD Course for Beginners

This beginner-friendly course teaches you to write robust PHP code using Test-Driven Development (TDD) and PHPUnit. Learn to write effective tests, improve code quality, and gain confidence in your development. Includes live coding, practical assignments with individual feedback, recorded classes, and community support. Certificate of attendance offered. No prior testing experience needed.

Are you ready to write cleaner, more reliable PHP code? This beginner-friendly, 2-week intensive course will guide you through the fundamentals of Test-Driven Development (TDD) using PHPUnit, the industry-standard testing framework for PHP.

Stop fearing code changes and embrace confidence! Learn how to write tests before you write your application code, ensuring your software is not only functional but also maintainable and scalable.

What you’ll learn:

  • The core principles of TDD: Understand the Red-Green-Refactor cycle and how it drives development.
  • Setting up PHPUnit: Get your development environment ready and start writing your first tests.
  • Writing effective unit tests: Learn to test individual components of your application with precision.
  • Mastering PHPUnit assertions: Discover a wide range of assertions to verify the expected behavior of your code.
  • Testing different scenarios: Cover edge cases and ensure your code handles various inputs and outputs gracefully.
  • Mocking and stubbing: Learn to isolate your tests and manage dependencies effectively.
  • Organising your test suite: Structure your tests for clarity and maintainability.
  • Applying TDD principles to real-world examples: Build practical projects and solidify your understanding.
  • Understanding code coverage: Measure the effectiveness of your tests and identify areas for improvement.
  • Using best practices and design patterns in your tests.

Why learn TDD with PHPUnit?

  • Improved Code Quality: Catch bugs early and prevent regressions.
  • Increased Confidence: Deploy code with assurance, knowing it’s thoroughly tested.
  • Faster Development Cycles: Reduce debugging time and streamline your workflow.
  • Maintainable Codebase: Create code that’s easier to understand and modify.
  • Enhanced Collaboration: Write code that’s easier for others to contribute to.

This course is perfect for:

  • Beginner PHP developers looking to improve their coding practices.
  • Developers who want to learn how to write robust and reliable code.
  • Anyone who wants to gain a solid foundation in TDD using PHPUnit.

What to Expect:

  • Duration: 2 weeks, with 3 one-hour classes per week.
  • Interactive Learning: Each class will feature live coding demonstrations, Q&A sessions, and opportunities for active participation.
  • Practical Assignments: You’ll receive graded take-home assignments after each class, designed to reinforce the concepts you’ve learned.
  • Individualised Feedback: You’ll receive constructive and specific feedback on your assignments, highlighting both your strengths and areas for improvement.
  • Resource Access: You’ll be provided with example code, supplementary resources, and access to recorded class sessions after each class.
  • Community Support: You’ll have access to a dedicated Slack channel for asking questions and interacting with fellow students outside of class time.
  • Recorded Classes: All classes will be recorded and made available to students after each session.
  • Certificate of Attendance: Students who are interested will receive a certificate of attendance upon completion of the course.

No prior testing experience is required! We’ll start from the basics and guide you step-by-step.

By the end of this course, you’ll be able to:

  • Write effective unit tests using PHPUnit.
  • Apply the principles of TDD to your PHP projects.
  • Build robust and maintainable PHP applications.
  • Increase your confidence as a PHP developer.
