[PATCH v3 4/8] test-lib: self-test that --verbose works

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



t0000 contains some light self-tests of test-lib.sh, but --verbose was
not covered.  Add a test.

The only catch is that the presence of a test harness influences the
output (specifically, the presence of some empty lines).  The easiest
fix is to unset TEST_HARNESS for the sub-test scripts.  This means
that we no longer check whether test-lib.sh works under the harness;
however, since running everything under 'prove' seems far more common
than the esoteric --verbose-only feature introduced in the next
commit, this seems the smaller risk.
