[PATCH 2/6] run-command tests: test stdout of run_command_parallel()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Extend the tests added in c553c72eed6 (run-command: add an
asynchronous parallel child processor, 2015-12-15) to test stdout in
addition to stderr. A subsequent commit will add additional related
tests for a new feature, making it obvious how the output of the two
compares on both stdout and stderr will make this easier to reason
about.
