emma - 未找到运行时覆盖率数据
emma - no runtime coverage data found
我无法定义为什么 emma 没有生成运行时覆盖率数据。
我在 运行 测试时忘记了什么？
基于此 post：
How to change Ant script with EMMA code-coverage so it can find runtime coverage data?
我把检测的类放在类路径的顶部

其实我做了一个非常糟糕的假设，我做错了......
经过几天的思考和浪费一些时间来理解这个问题..
我找到了解决方案：在 VM 中添加一个参数：
（对不起，我丢失了参考资料..）
<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" />

当您使用错误的命令生成报告时会出现此错误。大多数在线教程都提倡错误的（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 emma report -r html -in coverage.em, {ALFRESCO_HOME}\coverage.ec
EMMA: processing input files ...
EMMA: 1 file(s) read and merged in 60 ms
EMMA: nothing to do: no runtime coverage data found in any of the data files
命令的正确用法是（注意命令中有额外的“-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: processing input files ...
EMMA: 2 file(s) read and merged in 70 ms EMMA: writing [txt] report to [{JAVA_HOME}\jre\lib\ext\coverage.txt] ...
EMMA: writing [html] report to [{JAVA_HOME}\jre\lib\ext\coverage\index.html]
我无法定义为什么 emma 没有生成运行时覆盖率数据。
我在 运行 测试时忘记了什么？ 基于此 post： How to change Ant script with EMMA code-coverage so it can find runtime coverage data?
我把检测的类放在类路径的顶部

其实我做了一个非常糟糕的假设，我做错了......
经过几天的思考和浪费一些时间来理解这个问题.. 我找到了解决方案：在 VM 中添加一个参数： （对不起，我丢失了参考资料..）
<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}" />

当您使用错误的命令生成报告时会出现此错误。大多数在线教程都提倡错误的（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 emma report -r html -in coverage.em, {ALFRESCO_HOME}\coverage.ec
EMMA: processing input files ...
EMMA: 1 file(s) read and merged in 60 ms
EMMA: nothing to do: no runtime coverage data found in any of the data files
命令的正确用法是（注意命令中有额外的“-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: processing input files ...
EMMA: 2 file(s) read and merged in 70 ms EMMA: writing [txt] report to [{JAVA_HOME}\jre\lib\ext\coverage.txt] ...
EMMA: writing [html] report to [{JAVA_HOME}\jre\lib\ext\coverage\index.html]
