如何设置 Ant 任务以生成 Emma代码覆盖率报告？
最佳答案
要回答有关源目录和检测目录在哪里的问题(这些可以切换到您的标准目录结构):
<property file="build.properties" />
<property name="source" location="src/main/java" />
<property name="test.source" location="src/test/java" />
<property name="target.dir" location="target" />
<property name="target" location="${target.dir}/classes" />
<property name="test.target" location="${target.dir}/test-classes" />
<property name="instr.target" location="${target.dir}/instr-classes" />
类路径:
<path id="compile.classpath">
<fileset dir="lib/main">
<include name="*.jar" />
</fileset>
</path>
<path id="test.compile.classpath">
<path refid="compile.classpath" />
<pathelement location="lib/test/junit-4.6.jar" />
<pathelement location="${target}" />
</path>
<path id="junit.classpath">
<path refid="test.compile.classpath" />
<pathelement location="${test.target}" />
</path>
首先，您需要设置 Ant 可以在哪里找到 Emma 库:
<path id="emma.lib" >
<pathelement location="${emma.dir}/emma.jar" />
<pathelement location="${emma.dir}/emma_ant.jar" />
</path>
然后导入任务:
<taskdef resource="emma_ant.properties" classpathref="emma.lib" />
然后检测代码:
<target name="coverage.instrumentation">
<mkdir dir="${instr.target}"/>
<mkdir dir="${coverage}"/>
<emma>
<instr instrpath="${target}" destdir="${instr.target}" metadatafile="${coverage}/metadata.emma" mode="copy">
<filter excludes="*Test*"/>
</instr>
</emma>
<!-- Update the that will run the instrumented code -->
<path id="test.classpath">
<pathelement location="${instr.target}"/>
<path refid="junit.classpath"/>
<pathelement location="${emma.dir}/emma.jar"/>
</path>
</target>
然后使用正确的 VM 参数运行目标，例如:
<jvmarg value="-Demma.coverage.out.file=${coverage}/coverage.emma" />
<jvmarg value="-Demma.coverage.out.merge=true" />
最后生成您的报告:
<target name="coverage.report" depends="coverage.instrumentation">
<emma>
<report sourcepath="${source}" depth="method">
<fileset dir="${coverage}" >
<include name="*.emma" />
</fileset>
<html outfile="${coverage}/coverage.html" />
</report>
</emma>
</target>
