Rename all test utility classes with a "Test" prefix.
Review Request #11923 — Created Jan. 10, 2022 and submitted
We had a lot of test utility classes that had a
Testprefix for the
name, and these were being seen as candidates for unit tests. While nose
never complained, it still looked, and pytest is outright warning about
them, since they don't contain test methods.
This change renames all of those objects with a
avoiding this problem and making it clear what's a test suite and what's
Unit tests pass.
