我无法定义为什么 emma 不生成运行时覆盖率数据。

运行测试时我忘记了什么？基于这篇文章： How to change Ant script with EMMA code-coverage so it can find runtime coverage data?

我将检测类放在类路径的顶部

我第一次运行这个时，发生了这个错误::

    [junit] Running app.commons.enums.TypeFileSizeTest

    [junit]     0000020:

其实我做了一个非常糟糕的假设，我做错了……

经过几天的思考并浪费了一些时间来理解问题..我找到了解决方案：在VM中添加一个参数：（对不起，我失去了参考..）

<jvmarg value="-XX:-UseSplitVerifier" />

- 最后我只需要修改我的“emma-do-test”任务：

<target name="emma-do-test" depends="emma-instrumentation" >
    <junit printsummary="withOutAndErr" haltonfailure="true" fork="true"  >
        <classpath>
            <path refid="classpath.emma.run" />
        </classpath>
        <formatter type="plain" usefile="false" />
        <batchtest todir="${emma.report.dir}" >
            <fileset dir="${test.src.dir}" includes="**/*Test.java" />
        </batchtest>
        <jvmarg value="-XX:-UseSplitVerifier" />
        <jvmarg value="-Demma.coverage.out.file=${emma.runtime.coverage.data.file}" />
        <jvmarg value="-Demma.coverage.out.merge=false" />
    </junit>
    <echo message="Emma Test Result : ${emma.report.dir}" />
    <echo message="Emma file : ${emma.runtime.coverage.data.file}" />
</target>

当您使用错误的命令生成报告时，您会收到此错误。大多数在线教程都在提倡错误的（可能是旧的）命令，即使我在使用以下命令生成报告时也遇到了这个错误：

{JAVA_HOME}\jre\lib\ext>java -cp emma.jar 艾玛报告 -r html -in coverage.em, {ALFRESCO_HOME}\coverage.ec
EMMA：处理输入文件...
EMMA：1 个文件在 60 毫秒内读取和合并
EMMA：无事可做：在任何数据文件中都找不到运行时覆盖率数据

该命令的正确用法是（标记命令中有额外的“-in”）：

{JAVA_HOME}\jre\lib\ext>java -cp emma.jar emma report -r txt,html -in {JAVA_HOME}\jre\lib\ext\coverage.em -in C:\t1_tempSetup\Alfresco\coverage.ec 
EMMA：处理输入文件...
EMMA：在 70 毫秒内读取并合并了 2 个文件 EMMA：将 [txt] 报告写入 [{JAVA_HOME}\jre\lib\ext\coverage.txt] ...
EMMA：将 [html] 报告写入 [{JAVA_HOME}\jre\lib\ext\coverage\index.html]
