-"""produce code coverage reports using the 'coverage' package, including support for distributed testing.
-
-This plugin produces coverage reports. It supports centralised testing and distributed testing in
-both load and each modes. It also supports coverage of subprocesses.
-
-All features offered by the coverage package should be available, either through pytest-cov or
-through coverage's config file.
-
-
-Installation
-------------
-
-The `pytest-cov`_ package may be installed with pip or easy_install::
-
- pip install pytest-cov
- easy_install pytest-cov
-
-.. _`pytest-cov`: http://pypi.python.org/pypi/pytest-cov/
-
-
-Uninstallation
---------------
-
-Uninstalling packages is supported by pip::
-
- pip uninstall pytest-cov
-
-However easy_install does not provide an uninstall facility.
-
-.. IMPORTANT::
-
- Ensure that you manually delete the init_cov_core.pth file in your site-packages directory.
-
- This file starts coverage collection of subprocesses if appropriate during site initialisation
- at python startup.
-
-
-Usage
------
-
-Centralised Testing
-~~~~~~~~~~~~~~~~~~~
-
-Centralised testing will report on the combined coverage of the main process and all of it's
-subprocesses.
-
-Running centralised testing::
-
- py.test --cov myproj tests/
-
-Shows a terminal report::
-
- -------------------- coverage: platform linux2, python 2.6.4-final-0 ---------------------
- Name Stmts Miss Cover
- ----------------------------------------
- myproj/__init__ 2 0 100%
- myproj/myproj 257 13 94%
- myproj/feature4286 94 7 92%
- ----------------------------------------
- TOTAL 353 20 94%
-
-
-Distributed Testing: Load
-~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Distributed testing with dist mode set to load will report on the combined coverage of all slaves.
-The slaves may be spread out over any number of hosts and each slave may be located anywhere on the
-file system. Each slave will have it's subprocesses measured.
-
-Running distributed testing with dist mode set to load::
-
- py.test --cov myproj -n 2 tests/
-
-Shows a terminal report::
-
- -------------------- coverage: platform linux2, python 2.6.4-final-0 ---------------------
- Name Stmts Miss Cover
- ----------------------------------------
- myproj/__init__ 2 0 100%
- myproj/myproj 257 13 94%
- myproj/feature4286 94 7 92%
- ----------------------------------------
- TOTAL 353 20 94%
-
-
-Again but spread over different hosts and different directories::
-
- py.test --cov myproj --dist load
- --tx ssh=memedough at host1//chdir=testenv1
- --tx ssh=memedough at host2//chdir=/tmp/testenv2//python=/tmp/env1/bin/python
- --rsyncdir myproj --rsyncdir tests --rsync examples
- tests/
-
-Shows a terminal report::
-
- -------------------- coverage: platform linux2, python 2.6.4-final-0 ---------------------
- Name Stmts Miss Cover
- ----------------------------------------
- myproj/__init__ 2 0 100%
- myproj/myproj 257 13 94%
- myproj/feature4286 94 7 92%
- ----------------------------------------
- TOTAL 353 20 94%
-
-
-Distributed Testing: Each
-~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Distributed testing with dist mode set to each will report on the combined coverage of all slaves.
-Since each slave is running all tests this allows generating a combined coverage report for multiple
-environments.
-
-Running distributed testing with dist mode set to each::
-
- py.test --cov myproj --dist each
- --tx popen//chdir=/tmp/testenv3//python=/usr/local/python27/bin/python
- --tx ssh=memedough at host2//chdir=/tmp/testenv4//python=/tmp/env2/bin/python
- --rsyncdir myproj --rsyncdir tests --rsync examples
- tests/
-
-Shows a terminal report::
-
- ---------------------------------------- coverage ----------------------------------------
- platform linux2, python 2.6.5-final-0
- platform linux2, python 2.7.0-final-0
- Name Stmts Miss Cover
- ----------------------------------------
- myproj/__init__ 2 0 100%
- myproj/myproj 257 13 94%
- myproj/feature4286 94 7 92%
- ----------------------------------------
- TOTAL 353 20 94%
-
-
-Reporting
----------
-
-It is possible to generate any combination of the reports for a single test run.
-
-The available reports are terminal (with or without missing line numbers shown), HTML, XML and
-annotated source code.
-
-The terminal report without line numbers (default)::
-
- py.test --cov-report term --cov myproj tests/
-
- -------------------- coverage: platform linux2, python 2.6.4-final-0 ---------------------
- Name Stmts Miss Cover
- ----------------------------------------
- myproj/__init__ 2 0 100%
- myproj/myproj 257 13 94%
- myproj/feature4286 94 7 92%
- ----------------------------------------
- TOTAL 353 20 94%
-
-
-The terminal report with line numbers::
-
- py.test --cov-report term-missing --cov myproj tests/
-
- -------------------- coverage: platform linux2, python 2.6.4-final-0 ---------------------
- Name Stmts Miss Cover Missing
- --------------------------------------------------
- myproj/__init__ 2 0 100%
- myproj/myproj 257 13 94% 24-26, 99, 149, 233-236, 297-298, 369-370
- myproj/feature4286 94 7 92% 183-188, 197
- --------------------------------------------------
- TOTAL 353 20 94%
-
-
-The remaining three reports output to files without showing anything on the terminal (useful for
-when the output is going to a continuous integration server)::
-
- py.test --cov-report html
- --cov-report xml
- --cov-report annotate
- --cov myproj tests/
-
-
-Coverage Data File
-------------------
-
-The data file is erased at the beginning of testing to ensure clean data for each test run.
-
-The data file is left at the end of testing so that it is possible to use normal coverage tools to
-examine it.
-
-
-Coverage Config File
---------------------
-
-This plugin provides a clean minimal set of command line options that are added to pytest. For
-further control of coverage use a coverage config file.
-
-For example if tests are contained within the directory tree being measured the tests may be
-excluded if desired by using a .coveragerc file with the omit option set::
-
- py.test --cov-config .coveragerc
- --cov myproj
- myproj/tests/
-
-Where the .coveragerc file contains file globs::
-
- [run]
- omit = tests/*
-
-For full details refer to the `coverage config file`_ documentation.
-
-.. _`coverage config file`: http://nedbatchelder.com/code/coverage/config.html
-
-Note that this plugin controls some options and setting the option in the config file will have no
-effect. These include specifying source to be measured (source option) and all data file handling
-(data_file and parallel options).
-
-
-Limitations
------------
-
-For distributed testing the slaves must have the pytest-cov package installed. This is needed since
-the plugin must be registered through setuptools / distribute 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.
