[wp-hackers] Unit Testing, Yet Another Discussion

I decided to go with PHPUnit, since it is awesome and supports
everything I want out of box.
http://svn.dragonu.net/WordPress/UnitTest/ - Subversion Repository for
WordPress Unit Tests using PHP 5 and PHPUnit 3.1.4+ (I might have to
move this to google to easily allow others to modify the code, I forgot
that I have to add users and some people have issues with giving another
a password). At least you can tell me how bad it sucks.
I do not include PHPUnit, I do have a system to where I can
automatically get reports based on the unit tests. I also have a
generated (CRAP) index for all of WordPress Files (root and wp-includes).
The PHP 5.2 branch (not active while working on Unit Tests) is
elsewhere, since I doubt it would be of any interest. It is up one
folder in the repository root. I also do not structure it like you would
normally with trunk, tags, and branches, since the purpose is more
refine. There is also an external property for getting the trunk of
WordPress. However, the wp-tests folder is outside of that repository
and can be commited to without permissions to the Automattic repository.
If you want a username and password, email me privately (however, I
think it is also possible, maybe, to create a PHP script that can add
The Change Risk Analysis and Predictions Index is helpful in finding
which files are unit testable. The higher the number, the more logic is
in the file. If such logic is in functions or classes, then it can be
(at the bottom) has the results. It is useful in deciding which files
can be unit tested, which should be have characterizations tests, and
which should have acceptance tests (to test the whole of the functionality).
The only files I'll probably never test (directly) is gettext.php and
streams.php. That reminds me, you will have to patch your wp-includes
files for the plugin.php tests to pass. I will create patches of the
files and add them to a new folder. I had to patch plugin.php a lot.
