为什么JUnit测试在Ant Build System中失败？

Raj*_*pta 6 java ant junit

我是Java的新手,所以请温柔地对待我.我正在尝试使用Ant Build System来运行我的JUnit测试.但是当我在没有Ant的情况下运行我的测试时,它会通过,但是当我使用Ant Build来运行我的JUnit测试时,测试失败了.

这是我的Ant build.xml文件:

<property name="lib.dir" value="lib"/>

<path id="classpath">
    <fileset dir="${lib.dir}" includes="*.jar"/>
</path>

<target name="runjunit" depends="compile">
    <mkdir dir="reports" />
    <junit printsummary="true" showoutput="yes" haltonerror="yes" haltonfailure="yes"  >
        <test name="com.geometry.CartesianPositionTest" />
        <classpath>
            <path refid="classpath" />
            <pathelement location="out" />
        </classpath>
    </junit>
</target>

<target name="compile">
    <javac srcdir="src" destdir="out" includeantruntime="false" classpath="lib/junit-4.11.jar"/>
</target>

<target name="package" depends="compile">

         basedir="out"
         includes="**"
         excludes="**/*Test*" >
        <manifest>
            <attribute name="Main-Class" value="com.geometry.CartesianPosition" />
        </manifest>
    </jar>
</target>

19个目录,12个文件任何人都可以帮助我吗？提前致谢.

我设法让它与下面的构建文件一起工作。Ant 试图将其作为 junit 3 样式测试而不是 4 运行。我相信这是因为语言级别默认为 1.5。我还必须编译测试。之后出现了 NoClassDef 错误org/hamcrest/SelfDescribing。通过将 hamcrest jar 添加到 lib 解决了这个问题。

怎么修：

  1. 设置源码版本1.5以上
  2. 编译测试类
  3. 添加hamcrest-all-1.3.jar到lib
