Observation¶

See https://github.com/os-autoinst/os-autoinst/pull/1947#issuecomment-1030202917

https://app.codecov.io/gh/os-autoinst/os-autoinst/compare/1947/changes
The changes being marked for lost coverage are:

# backend/baseclass.pm
346        while ($select->count) {
347            $! = 0;
348            die($! ? "$!\n" : 'timeout exceeded') unless my @ready = $select->can_write($timeout);
349            for my $fh (@ready) {
350                if (defined $internal_pipe && $fh == $internal_pipe) {
351                    $self->_write_buffered_data_to_file_handle('Encoder', $video_data_for_internal_encoder, $fh);
352                    $select->remove($fh) unless @$video_data_for_internal_encoder;

Acceptance criteria¶

• AC1: Reliable coverage reports in codecov for backend/baseclass.pm

Suggestions¶

• Try to reach the according code path from unit tests because the problem is likely caused by tests which trigger the above code indirectly and depending on timing behaviour hit the code or not sometimes
• IO::Select is already mocked in t/23-baseclass.t so likely the same approach can be used here
• If it's hard to reach the code consider extracting methods that can be covered separately
