Dealing with risky tests

Automated testing is crucial for software quality. However, not all tests are equally valuable: risky tests can compromise reliability.

I will show you how to correctly interpret PHPUnit feedback in order to identify risky tests. You will learn how to transform such tests into useful ones through targeted refactoring, thereby improving test quality in the long term and making your test suite more robust.

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 PHPUnit feedback on your tests
• Refactoring risky tests into useful and valuable tests
• Boosting confidence in your test suite

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.
