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:

.. list-table::
   :header-rows: 1

   * - CLI Option
     - User Guide
     - Description

   * - default, |abstract-option-txt|
     - |abstract-guide-txt|
     - compact human-readable summaries

   * - |abstract-option-html|
     - |abstract-guide-html|
     - overview of all files

   * - |abstract-option-html-details|
     - |abstract-guide-html-details|
     - annotated source files

   * - |abstract-option-cobertura|
     - |abstract-guide-cobertura|
     - machine readable XML reports in Cobertura_ format

   * - |abstract-option-sonarqube|
     - |abstract-guide-sonarqube|
     - machine readable XML reports in Sonarqube format

   * - |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-csv|
     - |abstract-guide-csv|
     - CSV report summarizing the coverage of each file

   * - |abstract-option-coveralls|
     - |abstract-guide-coveralls|
     - machine readable JSON report in Coveralls_ 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 HTML reports:

::

    gcovr --html-details coverage.html

Gcovr will create one HTML report per source file 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_>`__.
