Codewars reporter ignores `@testdox` annotation

[hobovsky]

PHPUnit provides @testdox annotation, which allows custom titles for test classes and test methods. However, Codewars reporter emits <DESCRIBE::> and <IT::> which do not use custom titles.

The cause can be that the CW reporter uses $test->getName(), while custom titles seem to be obtained with \PHPUnit\Util\Test::describeAsString($test), as can be seen in the default reporter.

Escalated to CW-171

@hobovsky Can you help with the fix?

We should have some tests in this repo as well.

[hobovsky]

Sure, I will see what I can do.

After looking into the issue and runnign the setup locally, it turned out I was not completely right:

1. The @testdox annotation is not meant to work by default, with a default reporter. It works only when phpunit is run with --testdox parameter, and meant to generate so-called "agile documentation sentences".
2. Default reporter does not use @testdox at all, and is not able to read titles provided by the annotation.
3. However, it is be possible to use testdox utilities in CW reporter so it would report custom titles. But it's not what the default PHPUnit reporter does. Doing so would not be a bug fix, but an extension. The problem is that the prettifying of annotated and not annotated names is coupled together, and testdox prettifier cannot be easily used only for annotated names. This causes that if the CW reporter would use the testdox prettifier, also existing suites with not annotated tests will be affected, and turned into "agile documentation sentences".

I misinterpreted docs on @testdox annotation, and incorrectly assumed that the fact that it's not used on CW is a bug in CW reporter. It is not.

I created #5 so you can see how it works. Feel free to reject if the docfx prettification of not annotated titles is not desired.
