I just ran py.test
on my code and got the following output:
================== 6 passed, 2 pytest-warnings in 40.79 seconds =======================
However, I cannot see what py.test
would like to warn me about. How can I turn on warning output to the console?
py.test --help
offers me the --strict
flag:
--strict run pytest in strict mode, warnings become errors.
However I just want to see the output, not make my tests fail.
I checked pytest.org and this question but they are only concerned with asserting warnings in python, not showing warnings generated on the commandline.
-r chars show extra test summary info as specified by chars (f)ailed, (E)error, (s)skipped, (x)failed, (X)passed (w)pytest-warnings (a)all. This will allow to show warnings in the report (top portion of the record) will list which pytest plugins use deprecated arguments (in my case bellow):
Warning messages are displayed by warn() function defined in 'warning' module of Python's standard library.
Disabling warnings summary Although not recommended, you can use the --disable-warnings command-line option to suppress the warning summary entirely from the test run output.
In this case, pytest-warnings are warnings which were generated for pytest and/or it's plugins. These warnings were not generated for your code. In order to list them in the report, you will need to use option -r w
. Here is portion of py.test --help
:
