When the interpeter is missing, we get an exit code of 127. Let's treat those tests as skipped too. If we could run the test far enough so that it could do the check itself, it would return 77 anyway. $ test/asdf; echo $? exec: Failed to execute process 'test/asdf': The file specified the interpreter '/bin/asdf', which is not an executable command. 127 $ test/asdf; echo $? /usr/bin/env: ‘/bin/asdf’: No such file or directory 127 This should resolve the problem that TEST-02 fails or Debian's 'unit-tests' fail when python3 is not installed. Installing python3 via the mechanism that is used to construct TEST images, i.e. the dracut dependency chasing scheme, would be a lot of work for python with its modules in multiple locations and hundreds of little files. So I think it OK to just skip the test there, and also in other cases where python is not available.
