How to suppress py.test internal deprecation warnings

Question

Is there a way to suppress the pytest\'s internal deprecation warnings?

Context: I\'m looking to evaluate the difficulty of porting a test suite from nose

Answer 1

In the pytest.ini file you can add:

[pytest]
addopts = -p no:warnings

OR passing below line in the command-line. This might be useful if your test suites handle warnings using an external system.

-p no:warnings

OR if you only want to hide some specific deprecated warning, add below statement in you pytest.ini file

[pytest]
filterwarnings =
    ignore:.*U.*mode is deprecated:DeprecationWarning

This will ignore all warnings of type DeprecationWarning where the start of the message matches the regular expression ".*U.*mode is deprecated".

OR Although not recommended, you can use the

--disable-warnings

command-line option to suppress the warning summary entirely from the test run output.
