- Add upstream testsuite tests/Regression/upstream-testsuite
to the CI testplan. However, this one isn't a good measure
for gating, because it is too complex and flaky. But it's
good to have test results at hand. This testcase reports a
failure only in case of an infrastructure problem. Individual
.exp test failures are not a show stopper from the persp of
the CI gating.
- Add upstream systemtap build and install pseudo testcase.
tests/Install/upstream-systemtap to the testplan.
This one is disabled by default (in its main.fmf file). The
point here is to be able to test with upstream version of
systemtap in case a working fedora build isn't available.
This is a helper for manual testing, although if enabled, it
will do its job in the automated CI pipeline too.
- Use FMF tag instead of tier attributes to define the testplan.
- Testcase updates:
* tests/Regression/second-command-not-captured
* tests/Regression/python-probing
