Test Selection
--------------
Test selection is handled by a Selector. The test loader calls the
appropriate selector method for each object it encounters that it
thinks may be a test.

A class must be a unittest.TestCase subclass, or match test name
requirements. Classes that start with _ are always excluded.

All package directories match, so long as they do not match exclude.
All other directories must match test requirements.

a Is the file a wanted test file?
The file must be a python source file and match testMatch or
include, and not match exclude. Files that match ignore are *never*
wanted, regardless of plugin, testMatch, include or exclude settings.

� Z d S) r a� A test address represents a user's request to run a particular
test. The user may specify a filename or module (or neither),
and/or a callable (a class, function, or method). The naming
format for test addresses is:
filename_or_module:callable
Filenames that are not absolute will be made absolute relative to
the working dir.
The filename or module part will be considered a module name if it
doesn't look like a file, that is, if it doesn't exist on the file
system and it doesn't contain any directory separators and it
doesn't end in .py.
Callables may be a class name, function name, method name, or
class.method specification.
