Description: 

In PHPUnit 10,

PHPUnit no longer invokes a static method named `suite` on a class that is declared in a file that is passed as an argument to the CLI test runner

this will make the *TestSuite classes implemented in Drupal dead code.

Those classes are now deprecated.

Check PHPUnit's Organizing Tests documentation on how to compose test suites via the file system or via XML configuration.
