python-coverage - measure code coverage of Python program execution
Contents
Command Overview
python-coverageannotate
Annotate source files with execution information.
python-coveragecombine
Combine a number of data files.
python-coveragedebug
Display diagnostic information about the internals of this program.
python-coverageerase
Erase previously collected coverage data.
python-coveragehelp
Get help on using coverage.py.
python-coveragehtml
Create an HTML report.
python-coveragereport
Report coverage stats on modules.
python-coveragerun
Run a Python program and measure code execution.
python-coveragexml
Create an XML report of coverage results.
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.

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...
