Cobertura XML Output

The default output format for gcovr is to generate a tabular summary in plain text. The gcovr command can also generate a Cobertura XML output using the --cobertura and --cobertura-pretty options:

gcovr --cobertura-pretty

This generates an XML summary of the lines executed:

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE coverage SYSTEM ''>
<coverage line-rate="0.8571428571428571" branch-rate="0.5" lines-covered="6" lines-valid="7" branches-covered="1" branches-valid="2" complexity="0.0" timestamp="1706214941" version="gcovr 7.0">
    <package name="" line-rate="0.8571428571428571" branch-rate="0.5" complexity="0.0">
        <class name="example_cpp" filename="example.cpp" line-rate="0.8571428571428571" branch-rate="0.5" complexity="0.0">
            <line number="3" hits="1" branch="false"/>
            <line number="5" hits="1" branch="true" condition-coverage="50% (1/2)">
                <condition number="0" type="jump" coverage="50%"/>
            <line number="7" hits="0" branch="false"/>
            <line number="11" hits="1" branch="false"/>
            <line number="15" hits="1" branch="false"/>
            <line number="17" hits="1" branch="false"/>
            <line number="19" hits="1" branch="false"/>

This XML format is described in the Cobertura XML DTD suitable for import and display within the Jenkins and Hudson continuous integration servers using the Cobertura Plugin. Gcovr also supports a SonarQube XML Output.

The --cobertura option generates a denser XML output, and the --cobertura-pretty option generates an indented XML output that is easier to read. Note that the XML output contains more information than the tabular summary. The tabular summary shows the percentage of covered lines, while the XML output includes branch statistics and the number of times that each line was covered. Consequently, XML output can be used to support performance optimization in the same manner that gcov does.

New in version 5.1: The --cobertura and --cobertura-pretty options were added as an alias for -x/--xml and --xml-pretty, respectively. This avoids confusion with other XML output formats like SonarQube XML Output. The old options remain available for backwards compatibility.
