The shape and size of tests

Software testing is an essential part of quality assurance in software development. Here you will learn about the three dimensions of software testing: function, size, and implementation. These dimensions help to plan tests systematically and implement them effectively.

We discuss how different types of tests, from unit tests to integration tests to end-to-end tests, can be optimally combined to develop a robust testing strategy.

In addition, we highlight the role of visual models such as the test pyramid, which illustrate the structure of tests in a software project.

If you want to be sure that software works properly, you have to test it continuously. Tools such as PHPUnit are constantly being improved, as are best practices for their use.

It doesn't matter whether you already have many years of experience testing PHP software with PHPUnit or are just getting started in the world of testing, for example in our training courses Test Automation with PHPUnit or Advanced PHPUnit: When it comes to testing software, there is always something new to learn and old patterns to rethink.

In Tester's Corner, we concisely cover a topic related to automated software testing every month.

• Understanding the three dimensions of software testing
• Knowing visual models such as the test pyramid
• Finding the right test mix for your project

Tester's Corner is aimed at all developers who test their software with PHPUnit. Whether you are a beginner or an experienced user of PHPUnit, there is always something new to learn here.

Prerequisites are (at least initial) practical experience with PHPUnit and knowledge of object-oriented programming in PHP. The necessary basics are taught in the training courses Test Automation with PHPUnit and OOP Done Right.

• Understand PHPUnit, from the basics to advanced problem solving
• Gain comprehensive knowledge of lesser-known features and techniques
• Continuously optimise your test strategy to adapt it to new requirements.
