Domain-Specific Assertions

A common language that is understood by both technical and non-technical stakeholders is essential for good communication in a software project. By combining ideas from domain-specific design and test-driven development, this common language can be represented in both production and test code.

Here you will learn how to create tests that are easy to write, quick to execute and extremely reliable. You will gain knowledge about the safe and efficient implementation of automated tests for your software and see how custom assertions help to map your project's common language in the test code.

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.

• Implementing custom assertions for PHPUnit
• Applying domain-driven design concepts in testing as well
• Improving the readability of test code

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.
