Does pytest only print information when it fails?

Question

I am running some tests with pytests. These tests have print statements. However when all the tests pass, no info is ever printed. It is only when a test fails that along with the info about the failure, all prints that were executed get printed.

Is there a way to print info while the test run even when it passes?

You can use the -s option

Another way how you can see all print statements is to have a look into degenrated outputs, e.g. if you're using html reports or html1 reports, print statements are always captured there even when tests pass.

Thanks. I tried it, and yes it prints the prints of the test. But unfortunately it also prints the prints of the system I am testing. – KansaiRobot Jun 16 '20 at 12:12

You can add as command line argument --verbose or shortly -v to see whole log. It will include all steps: passed, failed, skipped and etc.

I am using this. It shows passed skipped instead of a dot. But it does not print the statments – KansaiRobot Jun 16 '20 at 12:11
Oh, sorry. You just should use logger instead of `print` statement – Andrei Jun 16 '20 at 16:01
