Implement group attribute on <directory> and <file> elements (children of <testsuite>) to add all tests found in a directory or file to a specified group

[mlahargou]

Problem:

We like to keep our unit tests fast (<1s). If they are slow, we want them to fail. Adding @small to every (100s) test class is a bit verbose and prone to forgetting to add it for new unit test classes.

Solution < v10:

We had a UnitTestCase that extended TestCase. That class overrode the getSize method to return return PHPUnit\Util\Test::SMALL. (I know getSize was marked as internal, but it was a workaround for the time being). All of our unit tests extended UnitTestCase.

Proposal :

It would be nice if there was a way to mark a directory as a certain size or if the @small annotation could be added to parent classes. In our case, we could add the @small annotation to UnitTestCase and then all of the children of that class would inherit that annotation.
