Innovation through collaboration: The highlights of PHPUnit 12.3

PHPUnit 12.3 introduces two new features developed collaboratively during training courses. The first is test suite-specific bootstrap scripts, a long-requested feature finally implemented using a participant-suggested approach. The second is the #[TestDoxFormatter] attribute, which allows fully customized TestDox output by invoking a method with data provider data — addressing limitations of the existing #[TestDox] attribute and placeholders. Both features emerged from real-world scenarios encountered during Advanced PHPUnit and Test-Driven Development workshops.
