我已经通过这个tutorial获取了我的ANT Script for emma / junit，它声明了
在
<classpath>的{{1}}元素中，更改实际类的位置，以便指向$ {instr.dir}属性而不是普通的目标/类文件夹。< / p>
以下是我的针对Apache Ant的build.xml的emma部分（pastebin链接到完整的build.xml）
<junit> <!-- =================================================================== -->
<!-- Run the tests with EMMA
* depends from compile -->
<!-- =================================================================== -->
<target name="emmatest" depends="compile" description="Tests the project with Emma Query" >
<!-- ======================================================================= -->
<!-- EMMA INSTRUMENTATION -->
<!-- ======================================================================= -->
<emma enabled="${emma.enabled}" >
<instr instrpathref="emma.coverage.classes"
destdir="${instr.dir}"
metadatafile="${coverage.dir}/metadata.emma"
merge="true"
>
<filter value="${emma.filter}" />
</instr>
</emma>
<junit fork="true" forkmode="once" >
<test name="test.nz.ac.massey.cs.sdc.log4jassignment.s06005586.AppenderLayoutTest" todir="${coverage.dir}">
<formatter type="xml"/>
</test>
<classpath>
<path refid="emma.lib" />
<pathelement location="${instr.dir}"/>
<fileset dir="${lib.dir}">
<include name="**/*.jar"/>
</fileset>
</classpath>
<jvmarg value="-Demma.coverage.out.file=${coverage.dir}/coverage.emma" />
<jvmarg value="-Demma.coverage.out.merge=false" />
</junit>
</target>
的构建部分结果： JUNIT失败结果，指向emma
${instr.dir} emmatest:
[instr] processing instrumentation path ...

[junit] Test test.nz.ac.massey.cs.sdc.log4jassignment.s06005586.AppenderLayoutTest FAILED
的构建部分结果： JUNIT通过结果，指向junitreport
real classes ${build.classes}我想知道为什么我的JUNIT测试test:
[junit] Running test.nz.ac.massey.cs.sdc.log4jassignment.s06005586.AppenderLayoutTest
[junit] Tests run: 2, Failures: 0, Errors: 0, Time elapsed: 0.504 sec

[junit] Tests run: 6, Failures: 0, Errors: 0, Time elapsed: 0.526 sec
与emma失败但是传递了junit。我也很自信我的AppenderLayoutTest没有被创建，因为coverage file的JUNIT失败了。
我是否使用错误的类测试？或者我错过了什么？
更新：2012年8月28日下午6:21
然后我改变了
AppenderLayoutTest带
<test
name="test.nz.ac.massey.cs.sdc.log4jassignment.s06005586.AppenderLayoutTest"
todir="${coverage.dir}">
<batchtest>
<fileset dir="${instr.dir}" includes="**/*Test.class" />
</batchtest>
更新后的构建部分结果： JUNIT失败结果，指向emma 其中..
${instr.dir}更新：下午7:02
我添加了emmatest:
[instr] processing instrumentation path ...
[instr] instrumentation path processed in 105 ms
[instr] [6 class(es) instrumented, 0 resource(s) copied]
[instr] metadata merged into [C:\Users\Michael\workspace\log4jassignment.s06005586\build\emma-reports\metadata.emma] {in 89 ms}

[junit] TEST test.nz.ac.massey.cs.sdc.log4jassignment.s06005586.StressTest FAILED

，这是输出

答案 0 :(得分：1)
您可以尝试更换
吗？<test
name="test.nz.ac.massey.cs.sdc.log4jassignment.s06005586.AppenderLayoutTest"
todir="${coverage.dir}">
带
<batchtest>
<fileset dir="${instr.dir}" includes="**/*Test.class" />
</batchtest>
最后，我会要求您在测试中加入一些sysout，看看测试中出了什么问题。这可能与我觉得的配置有关。
