pytest-hidecaptured 0.1.0

Hide captured output

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) as part of its report. For example:

==================================================================== test session starts =====================================================================

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 =====================================================================
