Gcovr provides a utility for managing the use of the GNU gcov_ utility and generating summarized code coverage results. This command is inspired by the Python coverage.py_ package, which provides a similar utility for Python.

The gcovr command can produce different kinds of coverage reports:

    • overview of all files

    • CSV report summarizing the coverage of each file
    • |abstract-option-json|
    • |abstract-guide-json|
    • JSON report with source file structure and coverage
    • |abstract-option-json-summary|
    • |abstract-guide-json-summary|
    • JSON summary coverage report
    • |abstract-option-clover|
    • |abstract-guide-clover|
    • machine readable XML reports in Clover_ format
    • |abstract-option-cobertura|
    • |abstract-guide-cobertura|
    • machine readable XML reports in Cobertura_ format
    • |abstract-option-coveralls|
    • |abstract-guide-coveralls|
    • machine readable JSON report in Coveralls_ format
    • |abstract-option-jacoco|
    • |abstract-guide-jacoco|
    • machine readable XML reports in JaCoCo_ format
    • |abstract-option-lcov|
    • |abstract-guide-lcov|
    • machine readable report in LCOV_ info format
    • |abstract-option-sonarqube|
    • |abstract-guide-sonarqube|
    • machine readable XML reports in SonarQube_ format

Thus, gcovr can be viewed as a command-line alternative to the lcov_ utility, which runs gcov and generates an HTML-formatted report. The development of gcovr was motivated by the need for text summaries and XML reports.

Installation

.. begin installation

Gcovr is available as a Python package that can be installed via pip_.

.. _pip: https://pip.pypa.io/en/stable

Install newest stable gcovr release from PyPI:

.. code:: bash

pip install gcovr

Install development version from GitHub:

.. code:: bash

pip install git+https://github.com/gcovr/gcovr.git

.. end installation

Quickstart

.. begin quickstart

GCC can instrument the executables to emit coverage data. You need to recompile your code with the following flags:

::

--coverage -g -O0

Next, run your test suite. This will generate raw coverage files.

Finally, invoke gcovr. This will print a tabular report on the console.

::

gcovr

You can also generate detailed or nested HTML reports:

::

gcovr --html-details coverage.html
gcovr --html-nested coverage.html

Gcovr will create one HTML report per source file and for --html-nested also per directory next to the coverage.html summary.

You should run gcovr from the build directory. The -r option should point to the root of your project. This only matters if you have a separate build directory. For example::

cd build; gcovr -r ..

.. end quickstart

For complete documentation, read the manual <documentation_>__.
