Passing tests started failing

The tests for one of my projects were passing last week on Appveyor but started failing this week. I can't even see which tests are failing.

Here are the logs:
Passing (last week):

Failing (this week):

No code changes were made during this week.

Can someone please help me understand why the tests are failing?

    OK, the image hasn't been changed (all images changes are logged here:, so it could mean some of the external dependencies of your project could have changed.

    Comparing both good and failing builds of the same commit I can see some difference - at least pip version is different, there might be other differences:

    Try enabling RDP ( and see if you can see pytest output.

    Thanks for the pointer to RDP. Very useful.

    Somehow, as soon as I started logging the outputs of pytest to a file, the tests started passing!
