pytest and coverage combination does not work

code-coverage, pytest, python

Solution

Try:

py.test --cov-report term --cov=. test.py

The `--cov` parameter takes an argument saying which paths to cover. In your example, `--cov` would consume `test.py`, but then there were no arguments left for py.test about which files to test.

UPDATE: as @hpk42 points out, you need to call your example something other than `pytest.py`. When I did this locally, I called it `test.py` instead.

Problem

I installed plugin for pytest from here:http://pypi.python.org/pypi/pytest-cov. Then I have a simple test code: pytest.py: ``` class TestNumbers: def test_int_float(self): assert 1 == 1.0 def test_int_str(self): assert 1 == 1 ``` I tried to test it with command: `py.test --cov-report term --cov pytest.py`. But it doesn't work. Even if I gave the entire absolute path of pytest.py it was still no data for collecting. However if I use `py.test pytest.py`, surely it tested Ok. I am very confusing about this problem, thanks for help.
