我一直在为我的 ant 脚本 for emma/junit阅读本教程,它指出
在 的
<classpath>
元素中<junit>
,更改真实类的位置,以便指向 ${instr.dir} 属性而不是正常的目标/类文件夹。
这是我的 Apache Ant 的 build.xml 中的 emma 部分(pastebin链接到完整的 build.xml)
<!-- =================================================================== -->
<!-- Run the tests with EMMA

<!-- =================================================================== -->
<target name="emmatest" depends="compile" description="Tests the project with Emma Query" >

<!-- ======================================================================= -->
<emma enabled="${emma.enabled}" >
<instr instrpathref="emma.coverage.classes"
destdir="${instr.dir}"
metadatafile="${coverage.dir}/metadata.emma"

>
<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=${coverage.dir}/coverage.emma" />
<jvmarg value="-Demma.coverage.out.merge=false" />
</junit>
</target>
构建部分结果emma
:JUNIT 失败结果,指向${instr.dir}
emmatest:

[junit] Test test.nz.ac.massey.cs.sdc.log4jassignment.s06005586.AppenderLayoutTest FAILED
构建部分结果为junitreport
:JUNIT Pass Result,指向real classes ${build.classes}

我想知道为什么我的 JUNIT 测试AppenderLayoutTest
在 emma 上失败但在 junit 上通过了。我也很有信心我coverage file
没有被创建,因为 JUNIT forAppenderLayoutTest
失败了。
我是否使用错误的类集进行测试?还是我错过了什么?
更新:2012 年 8 月 28 日下午 6:21
然后我改变了
<test
name="test.nz.ac.massey.cs.sdc.log4jassignment.s06005586.AppenderLayoutTest"
todir="${coverage.dir}">
和
<batchtest>
<fileset dir="${instr.dir}" includes="**/*Test.class" />
</batchtest>
以及更新的构建部分结果emma
:JUNIT Fail Result,指向${instr.dir}
哪里..

更新:下午 7:02
我添加了<formatter type="plain" usefile="false" />
,这是输出
