Question

我有一个关于与 Ant 脚本相关的 cobertura 的问题。我已经在 StackOverflow 上读过这两篇文章: SONAR - Measure Code Coverage using Cobertura和 Bamboo + sonar.dynamicAnalysis=reuseReports = 0% Rules Compliance

此外，我还在互联网上搜索了我的问题的解决方案。 现在我希望你能帮助我。

初始情况: 我有一个 Ant 脚本来编译一个库，然后编译一个测试目标。现在我添加了 cobertura。一段时间后，我发现类和 ser 文件都已存储。该报告也已生成，但没有覆盖范围。 但现在的问题是JUnit测试不起作用。在xml中可以发现如下错误信息:

<testcase classname="com.***.***.***.***.***Test" name="test16" time="0.0">
<error message="com/***/***/***/***/***Rule" type="java.lang.NoClassDefFoundError">java.lang.NoClassDefFoundError: com/***/***/***/***/***Rule
at com.***.***.***.***.***Test.setUp(Unknown Source)
at org.eclipse.ant.internal.launching.remote.EclipseDefaultExecutor.executeTargets(EclipseDefaultExecutor.java:32)
at org.eclipse.ant.internal.launching.remote.InternalAntRunner.run(InternalAntRunner.java:424)
at org.eclipse.ant.internal.launching.remote.InternalAntRunner.main(InternalAntRunner.java:138)

我目前在 Ant 脚本中使用以下代码:

<project name="MainLIB" default="vbuild" basedir="./">
<path id="path.additionaltasks">
    <fileset dir="../BUILD/antlib">
        <include name="cobertura.jar" />

    </cobertura-instrument>

    <junit printsummary="yes">
        <classpath>
            <!--<pathelement path="build/cobertura/classes" />-->
            <path refid="path.UNITTEST" />

        </classpath>
        <formatter type="xml" />

        <batchtest todir="${dir.build.test.report}">
            <fileset dir="${dir.build.test.classes}">
                <include name="**/*Test.class" />
            </fileset>
        </batchtest>
    </junit>

    <cobertura-report format="xml" datafile="${dir.build.cobertura}/cobertura.ser" destdir="${dir.build.cobertura}/" />
    <cobertura-report format="html" datafile="${dir.build.cobertura}/cobertura.ser" destdir="${dir.build.cobertura}/" />
</target>

问题是，这些类位于 build/cobertura/classes 目录中。我不明白为什么 Junit 找不到类

Answer 1

你的类路径:

    <classpath>
        <!--<pathelement path="build/cobertura/classes" />-->
        <path refid="path.UNITTEST" />

    </classpath>

包含:

<path id="path.LIB">
    <fileset dir="lib" includes="**/**.jar" />
</path>

<path id="path.UNITTEST">
    <path refid="path.LIB" />
    <pathelement path="build/cobertura/classes" />
    <pathelement path="build/classes" />
    <pathelement path="build/test-classes" />
</path>

但它还需要 cobertura jar，您可以在 path.additionaltasks 中引用它。 Cobertura 通过字节码操作来检测类文件。这些文件仍然需要 cobertura.jar 依赖项才能工作。
要修复此问题，请将 path.additionaltasks 添加到 junit:

    <classpath>
        <!--<pathelement path="build/cobertura/classes" />-->
        <path refid="path.UNITTEST" />
        <path refid="path.additionaltasks" />
    </classpath>
