Process stdout/stderr buffering > Firstly, when I execute run_dtests.py I don't see any output after > {{$ ./run_dtests.py --dtest-tests paging_test.py }} > {{============================= test session starts > ==============================}} > This looks likely to be because of the buffering that pytest does internally > for stdout and stderr and because of the way that it's executed by > run_dtests.py, i.e. I suspect that run_dtests.py is blocked on the following > line for most of the execution because there's no data available in the pipe > for stderr: > {{stderr_output = sp.stderr.readline()}} > See also [https://github.com/pytest-dev/pytest/issues/1886] > h2. --pytest-options doesn't work > Secondly, the options specified in --pytest-options aren't actually passed > through to pytest. > h2.
