Pytest not showing test results in the terminal window

Question

I'm trying to run some tests by invoking the pytest command at the command line in a directory containing tests. At the end, however, I see only how many tests passed or failed, but I don't see which ones, or the traceback the failed tests produced (see screenshot below).

Before I was seeing these things, and I don't recall changing anything in Pytest's configuration. What could be the issue?

Update

What is even more strange is that when I run some of the test scripts which I'm quite sure were displayed to yield test failures when run with pytest individually, the tests pass:

Could there be some kind of difference between calling the tests with the pytest command or the pytest [filename] command?

Answer 1

You can use

pytest -h

to show all of the info about possible flags and options. But the eisiest way to add more info to your tests adding -v flag, --verbose increase verbosity.

pytest your_test.py -v

f.i. if you have print() statement in your tests adding -s shows all of the results while running.

pytest your_test.py -v -s
