JaCoCo覆盖率报告设置（不包括测试班）
[英]JaCoCo coverage report setups(exclude test classes)
问题描述
Im generating a jacoco coverage report using the following target : 
我使用以下目标生成了jacoco覆盖率报告：
<target name="report" depends="test">
<!-- This task needs the collected execution data and ... -->
<executiondata>
<file file="${result.exec.file}" />
</executiondata>
<!-- the class files and optional source files ... -->
<structure name="JaCoCo Ant Example">
<classfiles>
<fileset dir="${result.classes.dir}" />
</classfiles>
<sourcefiles encoding="UTF-8">
<fileset dir="${src.dir}" >
<exclude name="**/*Test*.class"/>
</fileset>
</sourcefiles>
</structure>
<!-- to produce reports in different formats. -->
<html destdir="${result.report.dir}" />
<csv destfile="${result.report.dir}/report.csv" />
<xml destfile="${result.report.dir}/report.xml" />
</jacoco:report>
</target>
The problem is that the report takes into account the code from unit tests and I consider this fact a mistake. 问题在于该报告考虑了单元测试中的代码，我认为这一事实是错误的。 This way, your line coverage percent and instruction coverage will be artificially increased(because test lines are considered 100% covered) and report correctness is pretty affected. 这样，您的行覆盖率和指令覆盖率将被人为增加（因为测试行被视为100％覆盖了），并且报告的正确性受到很大影响。 I tried to add this tag 我试图添加此标签
<exclude name="**/*Test*.class"/
under fileset tag, hoping that testClasses will be excluded, but it doesnt works. 在文件集标签下，希望将testClasses排除在外，但它不起作用。 Do you have any ideas for my problem? 您对我的问题有任何想法吗？ I want to avoid programmatically report modification. 我想避免以编程方式报告修改。 Thanks! 谢谢！

You need to exclude the Test class files from the classfiles fileset: 您需要从类文件文件classfiles排除测试类文件：
<structure name="JaCoCo Ant Example">
<classfiles>
<fileset dir="${result.classes.dir}">
<exclude name="**/*Test*.class"/>
</fileset>
</classfiles>
<sourcefiles encoding="UTF-8">
<fileset dir="${src.dir}" />
</sourcefiles>
</structure>
See documentation : 参见文档 ：
"Note that the classfiles and sourcefiles elements accept any Ant resource collection. Therefore also filtering the class file set is possible and allows to narrow the scope of the report , for example:
<classfiles>
<fileset dir="classes">
<include name="org/jacoco/examples/important/**/*.class"/>
</fileset>
</classfiles>
This is because the actual report is done from the classfiles . 这是因为实际报告是从classfiles完成的。 The sourcefiles are there to include highlighted source code in the report - as of course the human eye can't read compiled code. sourcefiles在报告中包含突出显示的源代码-当然，人眼无法阅读编译后的代码。
Again from the documentation: 再次从文档中：
classfiles : Container element for Ant resources and resource collections that can specify Java class files, archive files (jar, war, ear etc. or Pack200) or folders containing class files.
sourcefiles : Optional container element for Ant resources and resource collections that specify corresponding source files.
