Test process should be documented

[jblz]

I don't see any explicit instructions as to how to run the test suite. If there aren't already any that I've missed, it'd be good to add some :)

Good idea. It's pretty simple I'd say something like:

The class included a set of PHPUnit tests. To run them, call phpunit from the plugin directory.

Does that cover it? Where do you think that belongs? in the README? or the class docblock? both?

[jblz]

I think the README(s) would be best.
