Using py.test --cov from inside setup.py pytest.main

Question

I'm developing a package with some testing.

Working with CMD:

py.test --cov my_pkg

I get the results with covarage:

--------------- coverage: platform win32, python 2.7.9-final-0 ----------------
Name                            Stmts   Miss  Cover
---------------------------------------------------
my_pkg\__init__       8      0   100%
my_pkg\general        2      0   100%
---------------------------------------------------
TOTAL                              10      0   100%

Fails:

when trying to integrate it inside pytest.main() and running with:

python setup.py test

with the following:

============================= test session starts =============================
platform win32 -- Python 2.7.9 -- py-1.4.26 -- pytest-2.7.0
rootdir: C:\Users\kobi.kalif\Projects\automation_utilities, inifile:
plugins: cov, xdist

ERROR: file not found: --cov my_pkg

Relevant Code:

class PyTest(test_command):
    """class py.test for the testing

    """
    user_options = []

    def __init__(self, dist, **kw):
        test_command.__init__(self, dist, **kw)
        self.pytest_args = ["--cov my_pkg"]

.....

    def run_tests(self):
        # import here, cause outside the eggs aren't loaded
        import pytest
        err_no = pytest.main(self.pytest_args)
        sys.exit(err_no)

Question:

How can i run tests with coverage from inside the setup.py file pytest.main?

Answer 1

According to the documentation you should either do:

self.pytest_args = ["--cov", "my_pkg"]

or:

self.pytest_args = "--cov my_pkg"
