The test is still passing as of today: http://slicer.cdash.org/testSummary.php?project=1&name=py_RSNA2012Quant&date=2013-05-07

Steve disabled ChangeTracker part of test, so now the test will keep passing, but (maybe) legitimately.

In this case the self test never has a chance to run because the module itself is not loaded. We should probably add another test that confirms the self-test module gets loaded.

Steve: yes, so the test (before the change) was exercising the (in)capability of the testing framework to detect the situation when a dependency was not satisfied.

It's a small point, but I would say that actually we just didn't have a test which checked if the module loaded. This would be an easy one to write.

It seems that only ChangeTracker module test is missing (that would check if the module is loaded and works correctly). Self-tests don't replace basic module tests but add more, higher-level testing.
