Teardown after all tests have run

[drFrankWhite]

Each of my test classes has its own teardown, but how do I write a teardown that runs once all tests finish? Similar to Pytest's scope=module, or maybe session

[mdmintz]

To have a special tearDown after all tests have run, override tearDownClass(), similar to how Syntax Format 2 overrides tearDown() in SeleniumBase/examples/boilerplates/base_test_case.py

Looks like someone did something like that here: #317 (comment)
