We use PHPs new namespaces, thus our class names contain backslashes. This profoundly confuses the
generation of the test result overview page. For a test that is shown with a name like
F3\FLOW3\SomeTest.testNameHere
the URL generated is
http://.../testReport/(root)/F3/FLOW3/SomeTest/testNameHere
That results in a 404, correct would be
http://.../testReport/(root)/F3%5CFLOW3%5CSomeTest/testNameHere
which works fine if entered manually. Thus \ needs to be escaped to %5C rather than replaced by /.

If you need more info or some help with testing things, let me know.

This has some similarity to what has been described in #1768, it seems test result URLs could be more
robust.
