              Create an HTML report.

       python-coveragereport
              Report coverage stats on modules.

       python-coveragerun
              Run a Python program and measure code execution.

       python-coveragexml

Command Reference

annotate
          Options:

          -dDIR,--directoryDIR
                 Write the output files to DIR.

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

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

       debugtopic
          Display information on the internals of coverage.py, for diagnosing problems.

          Topics are:

          • data, to show a summary of the collected data.

          • sys, to show installation information.

       erase
          Erase previously collected coverage data.

       help [ command ]
          Describe how to use Coverage.

       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:

          -dDIR,--directoryDIR
                 Write the output files to DIR.

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

          --fail-underMIN
                 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-underMIN
                 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.

          --debugDEBUGOPT,...
                 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!

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

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

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

Description

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

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.

Global Options

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

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

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

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

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.
