A cohomology test. This test measures the null space of various operators, which are topology-dependent and therefore are rather nice as tests, since they do not require fine meshes.
mesh file
Added docstrings for each individual test.
Update mesh files to include boundary conditions.

Use pytest to parametrize tests.
Added the cohomology for boundary conditions.
Forgot to check for enriched element in the betti0 test.
