实施例

Question

我的Java JUnit测试位于结构：src/com/project/test/test_junit.java

我的蚂蚁脚本是：

<project name="Test" basedir="." default="unit-test">


    <property name="src" value="src"/>
    <property name="build-test-classes" value="${src}/com/project/test"/>
    <property name="lib" value="lib"/>
    <property name="junit4" value="lib/junit-4.12.jar"/>

    <target name="unit-test">

        <junit printsummary="yes" haltonfailure="yes">
            <formatter type="plain" usefile="false"/>
            <classpath>
                <pathelement location="${junit4}"/>
                <pathelement location="${build-test-classes}"/>
            </classpath>
            <batchtest>
                <fileset dir="${build-test-classes}">
                    <include name="**/*.java"/>
                </fileset>
            </batchtest>
        </junit>
    </target>
</project>

PS：我更改了一些名称以制作不太具体的代码。

在运行Ant脚本时，我遇到以下问题：

unit-test:
    [junit] Running test_junit
    [junit] Testsuite: test_junit
    [junit] Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 0 sec
    [junit] Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 0 sec
    [junit] 
    [junit]     Caused an ERROR

我已经在这里看了很多问题，但似乎任何答案都解决了我的问题。

我敢打赌你还没有编译测试代码。提示是build-test-classes属性，它指向源代码树中的文件：

<property name="src" value="src"/>
<property name="build-test-classes" value="${src}/com/project/test"/>

实施例

创建一个编译源代码的目标

<target name="compile" depends="resolve,resources" description="Compile code">
    <mkdir dir="${build.dir}/classes"/>
    <javac srcdir="${src.dir}" destdir="${build.dir}/classes" includeantruntime="false" debug="true" classpathref="compile.path"/>
</target>

创建一个编译测试代码的目标

<target name="compile-tests" depends="compile" description="Compile tests">
    <mkdir dir="${build.dir}/test-classes"/>
    <javac srcdir="${test.src.dir}" destdir="${build.dir}/test-classes" includeantruntime="false" debug="true">
        <classpath>
            <path refid="test.path"/>
            <pathelement path="${build.dir}/classes"/>
        </classpath>
    </javac>
</target>

然后Junit应该工作

<target name="test" depends="compile-tests" description="Run unit tests">
    <mkdir dir="${build.dir}/test-reports"/>
    <junit printsummary="yes" haltonfailure="yes">
        <classpath>
            <path refid="test.path"/>
            <pathelement path="${build.dir}/classes"/>
            <pathelement path="${build.dir}/test-classes"/>
        </classpath>
        <formatter type="xml"/>
        <batchtest fork="yes" todir="${build.dir}/test-reports">
            <fileset dir="${test.src.dir}">
                <include name="**/*Test*.java"/>
                <exclude name="**/AllTests.java"/>
            </fileset>
        </batchtest>
    </junit>
</target>

用于运行junit测试的Ant脚本，显示java.lang.ClassNotFoundException
