In my particular case I wanted to know whether there is already some config
vector for 'please use this test directory for file tests'. As I didn't find
one in any API, I also looked for environment variables to be sure. Especially
as there are a bunch of qtest related environment variables already.
In general though it is common nowadays, at least being able to output all
config vectors in a build chain, especially if it is required to investigate
build- and test-issues on foreign/remote machines, which includes environment
variables.
Staying in the context of writing test cases: there are a bunch of other use
cases that would come to my mind from the PoV of a test case author:
"Is there an option for short vs. long tests?", "Is there a desired size
limitation for large file tests?", "Is there a deadline for the runtime of
tests?", ...
