TD: Standardize on test utilities for cleanup #798
Description
This originated from the Test Context class introduced in #750.
I believe this is a great start for our testing utilities around proper cleanup.
I believe that a Test Context class, in combination with TestFileGuard (Thanks Timothy for the suggestion - see #789), is a better approach than doing cleanup in each test, or using simple vectors like we (terrible idea by me 😅) started doing in the zowex.ds.test.cpp
Curious if we should leverage similar Context classes for other tests (instead of relying on a rudimentary vector-like implementation) 😋
