DESCRIPTION

       python-coverage  executes  a Python program, measures which of its statements are executed
       and which are not, and reports these coverage measurements.

COMMAND OVERVIEW

       python-coverage annotate
              Annotate source files with execution information.

       python-coverage combine
              Combine a number of data files.

       python-coverage erase
              Erase previously collected coverage data.

       python-coverage help
              Get help on using coverage.py.

       python-coverage html
              Create an HTML report.

       python-coverage report
              Report coverage stats on modules.

       python-coverage run
              Run a Python program and measure code execution.

       python-coverage xml
              Create an XML report of coverage results.

GLOBAL OPTIONS

       --help, -h
              Describe how to use Coverage, in general or a command.

       --rcfile RCFILE
              Specify configuration file RCFILE. Defaults to .coveragerc.

       --omit PATTERN ...
              Omit files when their filename  matches  one  of  these  PATTERNs.   Usually  needs
              quoting on the command line.

       --include PATTERN ...
              Include  files only when their filename path matches one of these PATTERNs. Usually
              needs quoting on the command line.

COMMAND REFERENCE

       annotate
          Options:

          -d DIR, --directory DIR
                 Write the output files to DIR.

          -i, --ignore-errors
                 Ignore errors while reading source files.

       combine
          Combine data from multiple coverage files collected with run -p.  The combined  results
          are written to a single file representing the union of the data.

       erase
          Erase previously collected coverage data.

       help [ command ]
          Describe how to use Coverage.

       help classic
          Describe help on older command syntax.

       html [ option ... ] [ MODULE ... ]
          Create an HTML report of the coverage of each MODULE file. Each file gets its own page,
          with the source decorated to show executed, excluded, and missed lines.

          Options:

          -d DIR, --directory DIR
                 Write the output files to DIR.

          --title TITLE
                 Use the text string TITLE as the title on the HTML.

          --fail-under MIN
                 Exit with a status of 2 if the total coverage is less than MIN.

          -i, --ignore-errors
                 Ignore errors while reading source files.

       report [ option ... ] [ MODULE ... ]
          Report coverage statistics on each MODULE.

          Options:

          --fail-under MIN
                 Exit with a status of 2 if the total coverage is less than MIN.

          -i, --ignore-errors
                 Ignore errors while reading source files.

          -m, --show-missing
                 Show line numbers of statements in each module that weren't executed.

       run [ options ... ] PROGRAMFILE [ program_options ]
          Run a Python program PROGRAMFILE, measuring code execution.

          Options:

          -a, --append
                 Append coverage data to .coverage, otherwise it is started clean with each run.

          --branch
                 Measure branch coverage in addition to statement coverage.

          --debug DEBUGOPT,...
                 Debug options DEBUGOPT, separated by commas

          -L, --pylib
                 Measure coverage even inside the Python installed library, which isn't  done  by
                 default.

          -p, --parallel-mode
                 Append the machine name, process id and random number to the .coverage data file
                 name to simplify collecting data from many processes.

          --timid
                 Use a simpler but slower trace method. Try this if you get seemingly  impossible
                 results!

          --source SOURCE ...
                 A list of packages or directories of code to be measured.

       xml [ options ... ] [ MODULES ... ]
          Generate an XML report of coverage results on each MODULE.

          Options:

          --fail-under MIN
                 Exit with a status of 2 if the total coverage is less than MIN.

          -i, --ignore-errors
                 Ignore errors while reading source files.

          -o OUTFILE
                 Write the XML report to OUTFILE. Defaults to coverage.xml.

ENVIRONMENT VARIABLES

       COVERAGE_FILE
          Path  to  the  file  where  coverage  measurements  are collected to and reported from.
          Default: .coverage in the current working directory.

       COVERAGE_OPTIONS
          Space-separated series of command-line options to python-coverage. Default: empty.

HISTORY

       The python-coverage command is a Python program which calls the coverage Python library to
       do all the work.

       The  library  was  originally  developed  by  Gareth  Rees,  and  is  now developed by Ned
       Batchelder.
