        ==========
        
        This plugin produces coverage reports using the coverage package.  It
        supports centralised testing and distributed testing in both load and
        each modes.
        
        All features offered by the coverage package should be available,
        either through this plugin or through coverage's own config file.
        
        
        Installation
        ------------
        
        This plugin depends on features just added to py and pytest-xdist.
        Until py 1.2.2 and pytest-xdist 1.2 are released you will need to
        install the 'tip' development versions from:
        
        http://bitbucket.org/hpk42/py-trunk/downloads/
        
        http://bitbucket.org/hpk42/pytest-xdist/downloads/
        
        
        Usage
        -----
        
        Centralised Testing
        ~~~~~~~~~~~~~~~~~~~
        
        Running centralised testing::
        
        py.test --cov myproj tests/
        
        Shows a terminal report::
        
        -------------------- coverage: platform linux2, python 2.6.4-final-0 ---------------------
        Name                 Stmts   Exec  Cover   Missing
        --------------------------------------------------
        myproj/__init__          2      2   100%
        myproj/myproj          257    244    94%   24-26, 99, 149, 233-236, 297-298, 369-370
        myproj/feature4286      94     87    92%   183-188, 197
        --------------------------------------------------
        TOTAL                  353    333    94%
        
        
        Distributed Testing
        ~~~~~~~~~~~~~~~~~~~
        
        Distributed testing with dist mode set to load and branch coverage
        enabled::
        
        py.test -n 2 --cov myproj --cov-branch tests/
        
        The results from the slaves will be combined like so::
        
        -------------------- coverage: platform linux2, python 2.6.4-final-0 ---------------------
        Name                 Stmts   Exec Branch BrExec  Cover   Missing
        ----------------------------------------------------------------
        myproj/__init__          2      2      0      0   100%
        myproj/myproj          257    244     56     50    93%   24-26, 99, 149, 233-236, 297-298, 369-370
        myproj/feature4286      94     87     18     13    89%   183-188, 197
        ----------------------------------------------------------------
        TOTAL                  353    333     74     63    92%
        
        
        Distributed testing in each mode::
        
        py.test --cov myproj --dist=each
        --tx=popen//python=/usr/local/python264/bin/python
        --tx=popen//python=/usr/local/python265/bin/python
        tests/
        
        Will produce a report for each slave::
        
        -------------------- coverage: platform linux2, python 2.6.4-final-0 ---------------------
        Name                 Stmts   Exec  Cover   Missing
        --------------------------------------------------
        myproj/__init__          2      2   100%
        myproj/myproj          257    244    94%   24-26, 99, 149, 233-236, 297-298, 369-370
        myproj/feature4286      94     87    92%   183-188, 197
        --------------------------------------------------
        TOTAL                  353    333    94%
        -------------------- coverage: platform linux2, python 2.6.5-final-0 ---------------------
        Name                 Stmts   Exec  Cover   Missing
        --------------------------------------------------
        myproj/__init__          2      2   100%
        myproj/myproj          257    244    94%   24-26, 99, 149, 233-236, 297-298, 369-370
        myproj/feature4286      94     87    92%   183-188, 197
        --------------------------------------------------
        TOTAL                  353    333    94%
        
        
        If desired distributed testing in each mode can instead produce a single combined report::
        
        py.test --cov myproj --cov-combine-each --dist=each
        --tx=popen//python=/usr/local/python264/bin/python
        --tx=popen//python=/usr/local/python265/bin/python
        tests/
        
        Which looks like::
        
        ---------------------------------------- coverage ----------------------------------------
        platform linux2, python 2.6.4-final-0
        platform linux2, python 2.6.5-final-0
        Name                 Stmts   Exec  Cover   Missing
        --------------------------------------------------
        myproj/__init__          2      2   100%
        myproj/myproj          257    244    94%   24-26, 99, 149, 233-236, 297-298, 369-370
        myproj/feature4286      94     87    92%   183-188, 197
        --------------------------------------------------
        TOTAL                  353    333    94%
        
        
        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.
        
        
        Acknowledgements
        ----------------
        
        Holger Krekel for pytest with its distributed testing support.
        
        Ned Batchelder for coverage and its ability to combine the coverage
        results of parallel runs.
        
        Whilst this plugin has been built fresh from the ground up to support
        distributed testing 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 for
        pytest and nose respectively.
        
        No doubt others have contributed to these tools as well.
