Python Testing with pytest

Plugins That Change the Normal Test Run Flow

The following plugins in some way change how pytest runs your tests.

pytest-repeat: Run Tests More Than Once

To run tests more than once per session, use the pytest-repeat plugin.^[35] This plugin is useful if you have an intermittent failure in a test.

Following is a normal test run of tests that start with test_list from ch7/tasks _proj_v2:

$ cd /path/to/code/ch7/tasks_proj_v2
$ pip install .
$ pip install pytest-repeat
$ pytest -v -k test_list
