t/18-qemu-options.t .. Dubious, test returned 255 (wstat 65280, 0xff00)
Failed 2/3 subtests
Running it without coverage or setting local $ENV{PERL5OPT}=""; in the test makes it pass.
Acceptance criteria¶
- AC1: Test is passing with coverage enabled

Compare the following two commands:¶
QEMU_QMP_CONNECT_ATTEMPTS=1 PERL_MYJSONRPC_DEBUG=1 perl /home/YOURUSER/openqa-devel/repos/os-autoinst/isotovideo -d qemu_disable_snapshots=1
QEMU_QMP_CONNECT_ATTEMPTS=1 PERL_MYJSONRPC_DEBUG=1 PERL5OPT="-MDevel::Cover=-select_re,'^/lib',-coverage,statement,-db,cover_db_t" perl /home/YOURUSER/openqa-devel/repos/os-autoinst/isotovideo -d qemu_disable_snapshots=1
You will see that sending magic and exit is printed twice in the second command (with coverage).
Additionally you will see backend got TERM.
No idea how to debug where that signal comes from.
I still think we should measure coverage only in unit tests, and running the whole isotovideo script as a new process, which itself forks, should be done without coverage enabled.

Both the commands OPENQA_TEST_TIMEOUT_DISABLE=1 PERL5OPT="-MDevel::Cover=-select_re,'^/lib',+ignore_re,lib/perlcritic/Perl/Critic/Policy,-coverage,statement,-db,cover_db_t" prove -l t/18-qemu-options.t and OPENQA_TEST_TIMEOUT_DISABLE=1 make coverage TESTS="t/18-qemu-options.t" work for me so I can't reproduce the original problem.
I am not quite sure I understand your latest statement
I still think we should measure coverage only in unit tests, and running the whole isotovideo script as a new process, which itself forks, should be done without coverage enabled.
Can you elaborate?
