Use Python Standard Library Regular Expressions to Specify Tests to Run
After installing locally with i.e., python -m pip install . you can
compare it with more conventional test selection techniques as follows.
Consider working with SciPy development. Let’s start off by selecting
all tests with test_3d anywhere in their node id, using the conventional/
built-in -k flag:
python dev.py test – -v -k “test_3d”
This runs a bunch of tests with string matches as you might expect:
scipy/io/tests/test_idl.py::TestArrayDimensions::test_3d PASSED
scipy/io/tests/test_idl.py::TestPointerArray::test_3d PASSED
scipy/optimize/_trustregion_constr/tests/test_qp_subproblem.py::TestBoxBoundariesIntersections::test_3d_box_constraints PASSED
scipy/optimize/_trustregion_constr/tests/test_qp_subproblem.py::TestBoxBoundariesIntersections::test_3d_box_constraints_entire_line PASSED
scipy/optimize/_trustregion_constr/tests/test_qp_subproblem.py::TestModifiedDogleg::test_3d_example PASSED
scipy/stats/tests/test_stats.py::TestGeometricStandardDeviation::test_3d_array PASSED
scipy/stats/tests/test_stats.py::TestGeometricStandardDeviation::test_3d_array_axis_type_tuple PASSED
scipy/stats/tests/test_stats.py::TestGeometricStandardDeviation::test_3d_array_axis_0 PASSED
scipy/stats/tests/test_stats.py::TestGeometricStandardDeviation::test_3d_array_axis_1 PASSED
scipy/stats/tests/test_stats.py::TestGeometricStandardDeviation::test_3d_array_axis_2 PASSED
scipy/stats/tests/test_stats.py::TestFOneWay::test_3d_inputs PASSED
What if you want to run only tests with an exact match to test_3d or
test_3d_example?
Try pytest-regex with:
python dev.py test – -v –regex “(.*test_3d|.∗test3dexample)”
scipy/io/tests/test_idl.py::TestArrayDimensions::test_3d PASSED
scipy/io/tests/test_idl.py::TestPointerArray::test_3d PASSED
scipy/optimize/_trustregion_constr/tests/test_qp_subproblem.py::TestModifiedDogleg::test_3d_example PASSED
This does what we want, and is probably more concise than the -k alternative. In fact,
I’m not entirely sure how one would do this with -k in its current form.
How it Works
pytest-regex simply passes the Python regular expression through
to the list of node ids, where a node id is structured as follows:
path/to/test_module.py::TestClass::test_name[parameter_value]
If the regex matches the node id, the test is retained and executed.
