Tests: tweaks for PHPUnit 10.x compatibility#64
Merged
Conversation
Initial tweaks to make the tests compatible with PHPUnit 10.x, which enforces a `mixed` return type for the `TestCase::runTest()` method. To test the TestListener, prior to PHPUnit 7.0, overloading the `runTest()` method works best, but as of PHPUnit 10.0, the `runTest()` method has a `mixed` return type declaration (PHP 8.0+). However, since PHPUnit 7.0, testing the TestListener also works when the test name with which the `TestCase` is instantiated is not `runTest()`. So either way, the fixtures used for the TestListener tests need to be duplicated and have two variations. Now the choice was which option to choose: * Duplicate the classes and add a return type to the `runTest()` method. * Duplicate the classes and rename the test method. I investigated both options and have decided to implement option 2 as `void` is not accepted as covariant with `mixed` and these methods are all `void` methods, so adding `mixed` as the return type would be misrepresenting the functionality. The toggle for which test class to load for the various tests has been implemented with a helper method.
