I am wondering why I never saw a need for this myself.

I do sometimes add 'set -x' into test functions in stragic places to see
a trace of the commands being run along with the test failure. Once I
have managed to fix a test I remove its 'set -x' lines again.
Does that solve the same problem?

I also often comment out tests in the long list at the bottom of
the file in order to run a single test case. I wish there was a
better solution but so far as it has not bothered me too much.
