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?

those packages need to be updated, that's all. They're still compatible, but won't be anymore in 3.8 that's what the message says — Jean-François Fabre

Thanks, but I have the latest packages installed from Anaconda and still get these warnings. — René

yes, precisely because the authors didn't fix the warnings yet. When I said "updated" I meant "updated by someone who will fix the code", not someone using "pip" to upgrade, since the upgrade doesn't exist yet. — Jean-François Fabre

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

I'm interested by the second option (in my case, the most recent version of the package is generating the same warnings). However, isn't setting the ignore::DeprecationWarning option also silences those warnings if there are other deprecations coming from my code? That's what I want to avoid.

@htaidirt you may use ignore:my regexp:DeprecationWarning to filter only DeprecationWarnings that match the regex.
