This plugin produces coverage reports. Compared to just using ``coverage run`` this plugin does some extras:
* Subprocess support: you can fork or run stuff in a subprocess and will get covered without any fuss.
* Xdist support: you can use all of pytest-xdist's features and still get coverage.
* Consistent pytest behavior. If you run ``coverage run -m pytest`` you will have slightly different ``sys.path`` (CWD will be
in it, unlike when running ``pytest``).
All features offered by the coverage package should work, either through pytest-cov's command line options or
through coverage's config file.
* Free software: MIT license
Installation
============
Install with pip::
pip install pytest-cov
For distributed testing support install pytest-xdist::
pip install pytest-xdist
Upgrading from ancient pytest-cov
---------------------------------
`pytest-cov 2.0` is using a new ``.pth`` file (``pytest-cov.pth``). You may want to manually remove the older
``init_cov_core.pth`` from site-packages as it's not automatically removed.
Uninstalling
------------
Uninstall with pip::
pip uninstall pytest-cov
Under certain scenarios a stray ``.pth`` file may be left around in site-packages.
* `pytest-cov 2.0` may leave a ``pytest-cov.pth`` if you installed without wheels
(``easy_install``, ``setup.py install`` etc).
* `pytest-cov 1.8 or older` will leave a ``init_cov_core.pth``.
Usage
=====
::
pytest --cov=myproj tests/
Would produce a report like::
-------------------- coverage: ... ---------------------
Name Stmts Miss Cover
----------------------------------------
myproj/__init__ 2 0 100%
myproj/myproj 257 13 94%
myproj/feature4286 94 7 92%
----------------------------------------
TOTAL 353 20 94%
Documentation

Coverage Data File
==================
The data file is erased at the beginning of testing to ensure clean data for each test run. If you
need to combine the coverage of several test runs you can use the ``--cov-append`` option to append
this coverage data to coverage data from previous test runs.
The data file is left at the end of testing so that it is possible to use normal coverage tools to
examine it.
Limitations
===========
For distributed testing the slaves must have the pytest-cov package installed. This is needed since
the plugin must be registered through setuptools for pytest to start the plugin on the
slave.
For subprocess measurement environment variables must make it from the main process to the
subprocess. The python used by the subprocess must have pytest-cov installed. The subprocess must
do normal site initialisation so that the environment variables can be detected and coverage
started.
Acknowledgements
================
Whilst this plugin has been built fresh from the ground up it has been influenced by the work done
on pytest-coverage (Ross Lawley, James Mills, Holger Krekel) and nose-cover (Jason Pellerin) which are
other coverage plugins.
Ned Batchelder for coverage and its ability to combine the coverage results of parallel runs.
Holger Krekel for pytest with its distributed testing support.
Jason Pellerin for nose.
Michael Foord for unittest2.
No doubt others have contributed to these tools as well.

disable coverage from command line.**

2.3.0 (2016-07-05)
------------------
* Add support for specifying output location for html, xml, and annotate report.
Contributed by Patrick Lannigan in `PR#113 <https://github.com/pytest-dev/pytest-cov/pull/113>`_.
* Fix bug hiding test failure when cov-fail-under failed.
* For coverage >= 4.0, match the default behaviour of `coverage report` and
error if coverage fails to find the source instead of just printing a warning.
Contributed by David Szotten in `PR#116 <https://github.com/pytest-dev/pytest-cov/pull/116>`_.
* Fixed bug occurred when bare ``--cov`` parameter was used with xdist.
Contributed by Michael Elovskikh in `PR#120 <https://github.com/pytest-dev/pytest-cov/pull/120>`_.
* Add support for ``skip_covered`` and added ``--cov-report=term-skip-covered`` command
line options. Contributed by Saurabh Kumar in `PR#115 <https://github.com/pytest-dev/pytest-cov/pull/115>`_.
2.2.1 (2016-01-30)
------------------
* Fixed incorrect merging of coverage data when xdist was used and coverage was ``>= 4.0``.
2.2.0 (2015-10-04)
------------------
* Added support for changing working directory in tests. Previously changing working
directory would disable coverage measurements in suprocesses.
* Fixed broken handling for ``--cov-report=annotate``.
2.1.0 (2015-08-23)
------------------
* Added support for `coverage 4.0b2`.
* Added the ``--cov-append`` command line options. Contributed by Christian Ledermann
in `PR#80 <https://github.com/pytest-dev/pytest-cov/pull/80>`_.
2.0.0 (2015-07-28)
------------------
* Added ``--cov-fail-under``, akin to the new ``fail_under`` option in `coverage-4.0`
(automatically activated if there's a ``[report] fail_under = ...`` in ``.coveragerc``).
* Changed ``--cov-report=term`` to automatically upgrade to ``--cov-report=term-missing``
if there's ``[run] show_missing = True`` in ``.coveragerc``.
* Changed ``--cov`` so it can be used with no path argument (in wich case the source
settings from ``.coveragerc`` will be used instead).
* Fixed `.pth` installation to work in all cases (install, easy_install, wheels, develop etc).
* Fixed `.pth` uninstallation to work for wheel installs.
* Support for coverage 4.0.
* Data file suffixing changed to use coverage's ``data_suffix=True`` option (instead of the
custom suffixing).
* Avoid warning about missing coverage data (just like ``coverage.control.process_startup``).
* Fixed a race condition when running with xdist (all the workers tried to combine the files).
It's possible that this issue is not present in `pytest-cov 1.8.X`.
