Python pytest warnings when running test

Question

I have a myfun.py file with my functions.
And I have a test_myfun.py file with pytest tests.

When running pytest test_myfun.py, the tests themselves run without errors, but pytest gives warnings.

Any suggestions how to solve these warnings?

Answer 1

You have two options.

1) Upgrade your packages, that is if the most recent versions of html5lib and scrapy have fixed these warnings.

2) Create a pytest.ini file in the root of your repo and give it these contents, which will make pytest ignore the DeprecationWarning

[pytest]
filterwarnings =
    ignore::DeprecationWarning
