phpunit configuration gives warnings

Module version(s) affected

Description

Running tests currently give warnings

Line 14:

• Element 'exclude': Element content is not allowed, because the type definition is simple.

Line 25:

• Element 'filter': This element is not expected.

I'm not sure there is a good reason to use the old syntax. Exclude is not allowed, so each directory needs to be added. Filter needs to be removed by coverage

How to reproduce

Run tests, see warnings
