我可以合并来自单元和集成测试目标的 Emma 覆盖率数据吗？

我们使用构建链设置 TeamCity 构建，以便我们的单元测试和集成测试可以在由提交触发时并行运行：

构建链 - 依赖于：
- 单元测试
- 集成测试

我正在寻找一种方法，我们可以组合/合并构建链中单元和集成测试生成的覆盖率数据，以便我们可以更好地了解实际情况代码被两者结合起来覆盖。

然后，计划是能够监视已提交代码的覆盖范围的变化，如果百分比下降，则可能会导致构建失败！

我已经设置了“构建链”目标，以便单元和集成目标中的覆盖文件（*.em、*.ec）可供使用。

我专门为构建链目标创建了一个 ant 构建文件（在 emma doco 的帮助下！）：

<project name="coverage-merge" basedir="." default="all">
    <!-- directory that contains emma.jar and emma_ant.jar: -->
    <property name="emma.dir" value="${basedir}/lib"/>
    <property name="coverage.dir" location="${basedir}/coverage"/>

    <path id="emma.lib">
        <pathelement location="${emma.dir}/emma-teamcity-3.1.1.jar"/>
        <pathelement location="${emma.dir}/emma_ant-2.0.5312.jar"/>
    </path>

    <taskdef resource="emma_ant.properties" classpathref="emma.lib"/>

    <target name="all" depends="-report"/>

    <target name="-report">
        <emma>
            <report sourcepath="${src.dir}" sort="+block,+name,+method,+class" 
                    metrics="method:70,block:80,line:80,class:100">
                <infileset dir="${coverage.dir}" includes="**/*.em, **/*.ec"/>

                <!-- for every type of report desired, configure a nested
                     element; various report parameters
                     can be inherited from the parent <report>
                     and individually overridden for each report type:
                -->
                <txt outfile="${coverage.dir}/coverage.txt" depth="package" 
                        columns="class,method,block,line,name"/>
                <xml outfile="${coverage.dir}/coverage.xml" depth="package"/>
                <html outfile="${coverage.dir}/coverage.html" depth="method" 
                        columns="name,class,method,block,line"/>
            </report>
        </emma>
    </target>
</project>

...它将所有覆盖率文件合并到一个报告中！

report 的 metrics 参数设置 html 报告的突出显示阈值，以便低于阈值的包和文件的百分比以红色突出显示。

修改 xml 输出将允许我使用类似 andariel 的东西对结果运行 xpath，然后强制如果未达到阈值，构建就会失败！

I have set up the 'build chain' target so that the coverage files (*.em, *.ec) from the unit and integration targets are available to it.

I created an ant build file specifically for the build chain target (with help from the emma doco!):

<project name="coverage-merge" basedir="." default="all">
    <!-- directory that contains emma.jar and emma_ant.jar: -->
    <property name="emma.dir" value="${basedir}/lib"/>
    <property name="coverage.dir" location="${basedir}/coverage"/>

    <path id="emma.lib">
        <pathelement location="${emma.dir}/emma-teamcity-3.1.1.jar"/>
        <pathelement location="${emma.dir}/emma_ant-2.0.5312.jar"/>
    </path>

    <taskdef resource="emma_ant.properties" classpathref="emma.lib"/>

    <target name="all" depends="-report"/>

    <target name="-report">
        <emma>
            <report sourcepath="${src.dir}" sort="+block,+name,+method,+class" 
                    metrics="method:70,block:80,line:80,class:100">
                <infileset dir="${coverage.dir}" includes="**/*.em, **/*.ec"/>

                <!-- for every type of report desired, configure a nested
                     element; various report parameters
                     can be inherited from the parent <report>
                     and individually overridden for each report type:
                -->
                <txt outfile="${coverage.dir}/coverage.txt" depth="package" 
                        columns="class,method,block,line,name"/>
                <xml outfile="${coverage.dir}/coverage.xml" depth="package"/>
                <html outfile="${coverage.dir}/coverage.html" depth="method" 
                        columns="name,class,method,block,line"/>
            </report>
        </emma>
    </target>
</project>

...which merges all the coverage files into a single report!

The metrics parameter of report sets the highlight threshold for the html report, so that the percentages against packages and files that are lower than the threshold are highlighted in red.

Modifying the xml output will allow me to use something like andariel to run an xpath over the results, and then force the build to fail if thresholds are not met!
