gcovrΒΆ

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:

CLI Option User Guide Description
default, --txt Text Output compact human-readable summaries
--html HTML Output overview of all files
--html-details HTML Output annotated source files
--cobertura Cobertura XML Output machine readable XML reports in Cobertura format
--sonarqube Sonarqube XML Output machine readable XML reports in Sonarqube format
--json JSON Output JSON report with source file structure and coverage
--json-summary JSON Output JSON summary coverage report
--csv CSV Output CSV report summarizing the coverage of each file
--coveralls Coveralls JSON Output 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.
