A Python script for summarizing gcov data.
generate GCC code coverage reports
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:
- default: compact human-readable summaries
- --xml: machine readable XML reports in Cobertura format
- --html: HTML summaries
- --html-details: HTML report with annotated source files
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.
Example HTML summary:
Example HTML details:
Gcovr is available as a Python package that can be installed via pip.
Install newest stable gcovr release from PyPI:
pip install gcovr
Install development version from GitHub:
pip install git+https://github.com/gcovr/gcovr.git
GCC can instrument the executables to emit coverage data. You need to recompile your code with the following flags:
-fprofile-arcs -ftest-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 -r .
You can also generate detailed HTML reports:
gcovr -r . --html --html-details -o 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 complete documentation, read the manual.
