如何为参数化的jUnit测试用例编写一个ant脚本？

Question

我写了参数化测试用例。当我通过蚂蚁运行它们时，我没有得到期望的结果。没有Parameterized，测试用例按需要运行。请让我知道我错在哪里以及我需要做些什么改变。

代码：

import java.util.Arrays; 
import java.util.Collection; 
import junit.framework.TestCase; 
import org.junit.Assert; 
import org.junit.Test; 
import org.junit.runner.RunWith; 
import org.junit.runners.Parameterized; 
import org.junit.runners.Parameterized.Parameters; 

@RunWith(value = Parameterized.class) 
public class HelloWorldTest extends TestCase { 

    int num1; 
    int num2; 
    int num3; 

    public HelloWorldTest(int num1, int num2, int num3) { 
     super(); 
     this.num1 = num1; 
     this.num2 = num2; 
     this.num3 = num3; 
    } 

    @Parameters 
    public static Collection<Object[]> data() { 
     Object[][] data = new Object[][] { { 1, 1, 2 }, { 2, 2, 5 } }; 
     return Arrays.asList(data); 
    } 

    @Test 
    public void testSummationPositive() { 
     Assert.assertEquals(num1 + num2, num3); 
    } 

} 

和Ant脚本：

<?xml version="1.0" encoding="UTF-8"?> 
<project name="HelloWorld" basedir="." default="main"> 

    <property name="src.dir" value="src" /> 
    <property name="test.dir" value="test" /> 
    <property name="build.dir" value="build" /> 
    <property name="classes.dir" value="${build.dir}/classes" /> 
    <property name="jar.dir" value="${build.dir}/jar" /> 

    <property name="main-class" value="HelloWorld" /> 

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

    <path id="application" location="${jar.dir}/${ant.project.name}.jar" /> 

    <target name="clean"> 
     <delete dir="${build.dir}" /> 
    </target> 

    <target name="compile"> 
     <mkdir dir="${classes.dir}" /> 
     <javac srcdir="${src.dir}" destdir="${classes.dir}" 
      classpathref="classpath" /> 
    </target> 

    <target name="test-compile"> 
     <mkdir dir="${classes.dir}" /> 
     <javac srcdir="${test.dir}" destdir="${classes.dir}" 
      classpathref="classpath" /> 
    </target> 

    <target name="jar" depends="compile,test-compile"> 
     <mkdir dir="${jar.dir}" /> 
     <jar destfile="${jar.dir}/${ant.project.name}.jar" basedir="${classes.dir}"> 
      <manifest> 
       <attribute name="Main-Class" value="${main-class}" /> 
      </manifest> 
     </jar> 
    </target> 

    <target name="run" depends="jar,junit"> 
     <java classname="${main-class}" fork="true"> 
      <classpath> 
       <path refid="classpath" /> 
       <path refid="application" /> 
       <path location="${jar.dir}/${ant.project.name}.jar"></path> 
      </classpath> 
     </java> 
    </target> 

    <target name="junit" depends="jar"> 
     <junit printsummary="yes"> 
      <classpath> 
       <path refid="classpath" /> 
       <path refid="application" /> 
      </classpath> 
      <batchtest fork="yes"> 
       <fileset dir="${test.dir}" includes="*Test.java" /> 
      </batchtest> 
     </junit> 
    </target> 

    <target name="clean-build" depends="clean,jar" /> 

    <target name="main" depends="clean,run" /> 
</project>

由于您使用JUnit 4中，你应该不需要extends TestCase声明。尝试删除它，看看你的测试是否正确运行。
