MoinMoin Testing Framework
--------------------------

All test modules must be named test_modulename to be included in the
test suite. If you are testing a package, name the test module
test_package_module.

Tests that require a certain configuration, like section_numbers = 1, must
use a Config class to define the required configuration within the test class.
