[galaxy-dev] Planemo 0.20.0 and xunit

Hi, I have recently upgraded to planemo 0.20.0 and I am getting an error that I cannot resolve: Cannot locate xUnit report option for tests - update Galaxy for more detailed breakdown. The output from the tool_test_output.json is empty {} I am using planemo t --install_galaxy I am a bit lost here, can anyone offer a suggestion please? I am afraid this might be too trivial... As a further note, I have this on the log: functional_tests.py: error: no such option: --with-nosehtml Many thanks, Tiago
