CREDO provides a set of core SysTest instantations, which supercede the functionality of the pre-existing test scripts system, which are documented below.
The user can always add to this list, by defining new SysTest classes to use.
The most flexible of the set is the SciBenchmarkTest, but this requires the most customisation (i.e. generally can’t be created in the short-hand form of the other tests using the sysTestRunner’s addStdTest() method).
depending on whether you have the Python Imaging Library (PIL) installed, you can also use the credo.systest.imageReference.ImageReferenceTest system test.
