JUnit 测试作为 ant 目标执行失败 [英] JUnit tests failed executed as an ant target

问题描述

我正在尝试使用适用于 Jenkins 的 Cobertura 插件获得代码覆盖率，因此我在我的 build.xml 中检测、运行测试和覆盖率报告，如下所示

I am trying to get code coverage using Cobertura plugin for Jenkins so I instrument, run tests and then coverage report in my build.xml as follow

问题是，当它尝试运行单元测试(我可以使用 ant test 运行)时，它一直在说

The thing is that when it tries to run the unit tests (which I can run using ant test) it keeps saying

module-test:
Running test cases...
Running coberturaandjenkins.CoberturaAndJenkinsTest
Tests run: 1, Failures: 0, Errors: 1, Time elapsed: 0 sec
Test coberturaandjenkins.CoberturaAndJenkinsTest FAILED

我已经更改，重新更改，重新更改 build.xml 好几天都没有任何运气.我不能让它工作.拜托，我很感激这里的任何帮助.这是我第一次使用 ant(和 Cobertura)

I have changed, re-changed, re-re-changed the build.xml without any luck for days. I can't get it work. Please, I'd appreciate any help here. It's the first time I'm using ant (and Cobertura)

推荐答案

感谢大家的回答.经过进一步调查，我想出了如何使其工作.我不得不完全重新编写 build.xml.这是:

Thanks for all your answers guys. After further investigation, I figured out how to make it work. I had to completely re-write the build.xml. Here it is:

<property file="build.properties" />

<path id="cobertura.classpath">
    <fileset dir="${cobertura.dir}">
        <include name="**/*.jar" />
    </fileset>
</path>

<taskdef classpathref="cobertura.classpath" resource="tasks.properties"/>

<target name="init">
    <mkdir dir="${classes.dir}" />
    <mkdir dir="${instrumented.dir}" />
    <mkdir dir="${reports.xml.dir}" />
    <mkdir dir="${reports.html.dir}" />
    <mkdir dir="${coverage.xml.dir}" />
    <mkdir dir="${coverage.summaryxml.dir}" />
    <mkdir dir="${coverage.html.dir}" />
</target>

<target name="compile" depends="init">
    <javac srcdir="${src.dir}" destdir="${classes.dir}" debug="yes" includeantruntime="false">

</target>

<target name="instrument" depends="init,compile">

            instrumented classes into ${build.instrumented.dir}.

    <cobertura-instrument todir="${instrumented.dir}">
        <!--
                The following line causes instrument to ignore any

        <classpath location="${instrumented.dir}" />

        <!--
