py.test: error: unrecognized arguments: --cov=ner_brands --cov-report=term-missing --cov-config

when I am trying to run my test through command line

    py.test  file_name.py

I got this error:

    py.test: error: unrecognized arguments: --cov=ner_brands --cov-report=term-missing --cov-config

How can I fix this?

pytest-cov package is required if you want to pass --cov arguments to pytest, by default it should not be passed though. Are you using a modified version of py.test?

    pip install pytest-cov

would fix your issue.
