Hi, I have just pushed a fix for this. In fact, the solution was proposed in one of the previous messages [1]: the test suite was returning True some time ago, but now it returns the exit code instead.
Some tests are `xfail`-ing (in the beginning I thought that's was the problem) but as I understood they are expected to fail and that's why they are ignored. For some other skipped tests, the extra dependencies are not satisfied. With regards, Liubov [1] https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=912586#25
