Thin wrapper around `subprocess.run`, intended for testing. Will mark fork() failures on Cygwin as expected failures: not a success, but not indicating a problem with the code either. Parameters ---------- args : list of str env : dict[str, str] timeout : float stdout, stderr check : bool text : bool Also called ``universal_newlines`` in subprocess. I chose this name since the main effect is returning bytes (`False`) vs. str (`True`), though it also tries to normalize newlines across platforms. capture_output : bool Set stdout and stderr to subprocess.PIPE Returns ------- proc : subprocess.Popen See Also -------- subprocess.run Raises ------ pytest.xfail If platform is Cygwin and subprocess reports a fork() failure. envtimeoutcheckstdoutstderrtextcygwinrNz Fork failure) subprocessPIPErunBlockingIOErrorsysplatformpytestxfail) commandrrrrrr capture_outputprocr(r r r subprocess_run_for_testing5s &   r-) extra_envc Gs`|j}|j}ttjdd|d|d|dg|itjddi|p#i|dtjtjdd }|S) a Run a function in a sub-process.
