小贝子编程

java.lang.classnotfoundexception与ant+Junit一起使用



我正在尝试运行一个简单的Ant脚本，但无法让它执行测试。我有太多的问题，我几乎不知道从哪里开始。我将从我用几个非常简单的测试用例创建的小型"简化"项目开始。最终，我想fork="yes"和forkmode="once"，但现在我在调试时已经关闭了它。

我的build.xml：

<?xml version="1.0" encoding="UTF-8"?>
<project name="Test1111" default="tests" basedir=".">
    <property name="projectName" value="Test1111"/>
    <property name="src" location="src"/>

    <property name="dist" location="dist"/>
    <property name="lib" location="lib"/>
    <path id="classpath">
        <fileset dir="${lib}">
            <include name="jmockit.jar"/>
        </fileset>
    </path>
    <target name="init">
        <tstamp/>
        <mkdir dir="${bin}"/>
    </target>
    <target name="compile" depends="init" description="compile the source">

        </javac>
        <copy todir="${bin}">
            <fileset dir="${src}" excludes="**/*.java"/>            
        </copy>
    </target>   
    <target name="tests" depends="compile" description="Run unit tests">
        <junit printsummary="withOutAndErr" fork="no" forkmode="once" haltonfailure="yes" failureproperty="junit.failure">
            <classpath path="lib/jmockit.jar"/>
            <classpath path="lib/junit.jar"/>
            <classpath path="lib/ant-junit.jar"/>
            <classpath path="lib/hamcrest-core.jar"/>
            <formatter type="plain" usefile="false"/>
            <batchtest>
                <fileset dir="${src}">
                    <include name="**/*Test*"/>
                    <exclude name="**/AllTests.java"/>
                </fileset> 
            </batchtest>
        </junit>
    </target>
    <target name="clean" description="clean up">
        <delete dir="${bin}"/>
    </target>
</project>

这是Ant控制台的输出，带有-verbose和-debug标志。

我在Windows上使用Eclipse，并在Eclipse中运行构建脚本。我觉得我什么都试过了，但我希望这里有人能认出可能出了问题

编辑：SimpleTest.java：

package simpletest.test;
import static org.junit.Assert.*;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import mockit.*;
import simpletest.SimpleClass;
import simpletest.SimpleInterface;
public class SimpleTest {
    static final class SimpleImpl implements SimpleInterface {
        public int doSomething() {
            System.out.println("HELLO WORLD");
            return 1;
        }
    }
    @Before
    public void setUp() throws Exception {
    }
    @After
    public void tearDown() throws Exception {
    }
    @Test
    public void testSomeInterface() {
        SimpleInterface si = new MockUp<SimpleInterface>() {
            @Mock
            int doSomething()
            {
                // intentionally left blank;
                return 1;
            }
        }.getMockInstance();
        assertEquals(1, si.doSomething());
    }
    @Test
    public void testInterfaceAgain() {
        final SimpleInterface thing = new SimpleImpl();
        /*
        new NonStrictExpectations(SimpleImpl.class) {{
            thing.doSomething(); result = 1;
        }};
        */
        final SimpleClass simple = new SimpleClass();
        simple.setSimpleInt(1);
        assertEquals(simple.getSimpleInt(), thing.doSomething());
    }
}

EDIT II:<pathelement path="${bin}"/>在类路径中丢失，似乎已经解决了问题（尽管仍然无法分叉）。很好。

simpletest.test.simpletest中有一个对类的引用，Ant找不到它。您必须确保Ant知道在哪里可以查找该类。

[junit] java.lang.ClassNotFoundException: simpletest.test.SimpleTest
[junit]     at java.net.URLClassLoader$1.run(URLClassLoader.java:366)

尝试更改

<batchtest>
    <fileset dir="${src}">
        <include name="**/*Test*"/>
        <exclude name="**/AllTests.java"/>
     </fileset> 
</batchtest>

至

<batchtest>
    <fileset dir="${bin}">
        <include name="**/*Test*"/>
        <exclude name="**/AllTests.java"/>
     </fileset> 
</batchtest>

看起来ant脚本找不到测试类，但<batchtest>任务应该能够将.class文件作为资源。

您应该只运行*Test类；你的额外通配符在最后会造成严重破坏。

此外，您需要将bin放在junit类路径上；如果没有它，junit实际上就没有任何可用的类定义。
