Yes. 'xftest...' means failing test. In the summary you get
separately number of expected and unexpected failures. When
testing FriCAS unexpected failure means something got
recently broken, so test machinery shouts about them.
OROH expected failures are known bugs, so no news.
If test normally expected to fail passes, then this
is also reported so that testsuite can be udjusted.
BTW: This is standard practice in testing: we do not want
expected bugs to produce too much clutter in the output,
but we still want to keep the test. Also, greping
testsuite for 'xftest' gives some idea about known bugs.
