Hide captured output

Project description

# pytest-hidecaptured

I write tests that generate a lot of debug messages to console and file.
pytest captures all output from tests and displays them when a test fails.
This behavior is exacerbated when there are a large number of tests within a
test run. Since I already log these messages to file I don't need pytest to
display them on the console. I'd rather it showed me its own reports only.

This issue is exacerbated when others run the same tests. All they care about
is whether the test passed or failed and don't need to see the details. In case
the test failed the debug log files already have the required information.

When any test fails pytest displays all captured output (stdout, stderr, log)
as part of its report. For example,

===== test session starts ======
platform darwin -- Python 3.5.1, pytest-2.8.5, py-1.4.31, pluggy-0.3.1
rootdir: /home/example/code, inifile:

===== FAILURES =====

test_logging.py:33: AssertionError

pytest-hidecaptured removes the captured output so it is not displayed. For
example, with pytest-hidecaputred installed, the report for the same test is,

===== test session starts ======
platform darwin -- Python 3.5.1, pytest-2.8.5, py-1.4.31, pluggy-0.3.1
