Well, per PEP 8, classes use CamelCaps, so your naming might break
automatic test discovery. Then, there might be another thing that could
cause this, and that is that if you have an intermediate class derived
from unittest.TestCase, that class on its own will be considered as test
case! If this is not what you want but you still want common
functionality in a baseclass, create a mixin and then derive from both
the mixin and unittest.TestCase for the actual test cases.
This is now standard practice, gradually being implemented everywhere in
the CPython test suite, for testing C and Py versions of a module.
class TestXyz():
mod = None
<test_a, etc, methods>
class TestXyz_C(TestXyz, TextCase): # Test C version
mod = support.import_fresh_module('_xyz') # approximately right
class TestXyz_Py(TestXyz, TextCase): # Test Python version
mod = support.import_fresh('xyz')
This minimizes duplication and ensures that both implementations get
exactly the same tests.
