Run trace.py with pytest

Question

I'm trying to get coverage using trace.py when running pytest. I know that pytest has its own coverage plugin pytest-cov but restrictions (number of times each line is executed is unavailable) do not allow me to use that right now. The same for coverage.py

I'm trying this command: python3.4 -m trace -c -m -C . pytest test_script.py

test_script.py:

class TestScript():
    def test_print(self):
        print ('Hello')

The output is:

nikhilh$ python3.4 -m trace -c -m -C . pytest test_script.py
pytest: Cannot run file 'pytest' because: [Errno 2] No such file or directory: 'pytest'

trace.py obviously expects a file in its arguments and not another module. How can I modify this command to get trace.py working with pytest?

Edit: I was able to find a way to get this done

nikhilh$ python3.4 -m trace -c -m -C . <pytest_script_absolute_path> test_script.py

I realize its been a bit since you posted this but could you make your solution an answer? – Dissolute

Does this answer your question? How do I run python's trace with pytest? – Talbot

@Talbot yep, that answer is what I came up with too. – Lambda

Answer 1

Came across David's comment, so here's the answer that I used at that time:

python3.4 -m trace -c -m -C . <pytest_script_absolute_path> test_script.py

Where can I find the pytest_script_absolute_path? I assume this means the script that is called when running pytest from terminal... – Rafa

Just followed the link above and was reminded of which pytest (or where pytest on Windows) – Rafa
