The issue was caused by missing g.region call in one of the tests [1, 2].

However, now I see at least 3 tests which were not failing before [3, 4,
5]. It seems like a trivial issue caused by some automatic changes (percent
operator is missing). This issue should be visible on any machine.

Also the error messages seems to be inappropriate. This should just fail
and not report an error (perhaps an except statement without an exception
specified?). And also the formatting is wrong since <> is missing around
the vector map name. Perhaps all three messages should be the same.

To run just one selected test use, for example:

cd scripts/v.what.strds/testsuite
python test_what_strds.py TestWhatStrds.test_output
