JUnit - ANT 插件

在这个例子中，我们将展示如何使用 ANT 运行 JUnit。让我们跟随以下步骤：

步骤 1:下载 Apache Ant

下载 Apache ANT

步骤 2:设置 Ant 环境

设置 ANT_HOME 环境变量来指向 ANT 函数库在机器中存储的基本文件地址。例如，我们已经在不同的操作系统的 apache-ant-1.8.4 文件夹中存储了 ANT 函数库。

附加 ANT 编译器地址到系统路径，对于不同的操作系统来说如下所示：

步骤 3:下载 Junit Archive

步骤 4:创建项目结构

• 在 C:\ > JUNIT_WORKSPACE 中创建文件夹 TestJunitWithAnt
• 在 C:\ > JUNIT_WORKSPACE > TestJunitWithAnt 中创建文件夹 src
• 在 C:\ > JUNIT_WORKSPACE > TestJunitWithAnt 中创建文件夹 test
• 在 C:\ > JUNIT_WORKSPACE > TestJunitWithAnt 中创建文件夹 lib
• 在 C:\ > JUNIT_WORKSPACE > TestJunitWithAnt >src 文件夹中创建 MessageUtil 类

/*
* This class prints the given message on console.
*/
public class MessageUtil {
   private String message;
   //Constructor
   //@param message to be printed
   public MessageUtil(String message){
      this.message = message; 
   }
   // prints the message
   public String printMessage(){
      System.out.println(message);
      return message;
   }   
   // add "Hi!" to the message
   public String salutationMessage(){
      message = "Hi!" + message;
      System.out.println(message);
      return message;
   }   
}

• 在 C:\ > JUNIT_WORKSPACE > TestJunitWithAnt > src 文件夹中创建 TestMessageUtil 类。

import org.junit.Test;
import org.junit.Ignore;
import static org.junit.Assert.assertEquals;
public class TestMessageUtil {
   String message = "Robert";   
   MessageUtil messageUtil = new MessageUtil(message);
   @Test
   public void testPrintMessage() { 
      System.out.println("Inside testPrintMessage()");     
      assertEquals(message,messageUtil.printMessage());
   }
   @Test
   public void testSalutationMessage() {
      System.out.println("Inside testSalutationMessage()");
      message = "Hi!" + "Robert";
      assertEquals(message,messageUtil.salutationMessage());
   }
}

• 在 C:\ > JUNIT_WORKSPACE > TestJunitWithAnt > lib 文件夹中复制 junit-4.10.jar。

创建 ANT Build.xml

我们将使用 ANT 中的 任务来执行我们的 junit 测试样例。

<project name="JunitTest" default="test" basedir=".">
   <property name="testdir" location="test" />
   <property name="srcdir" location="src" />
   <property name="full-compile" value="true" />
   <path id="classpath.base"/>
   <path id="classpath.test">
      <pathelement location="/lib/junit-4.10.jar" />
      <pathelement location="${testdir}" />
      <pathelement location="${srcdir}" />
      <path refid="classpath.base" />
   </path>
   <target name="clean" >
      <delete verbose="${full-compile}">
         <fileset dir="${testdir}" includes="**/*.class" />
      </delete>
   </target>
   <target name="compile" depends="clean">
      <javac srcdir="${srcdir}" destdir="${testdir}" 
         verbose="${full-compile}">
         <classpath refid="classpath.test"/>
      </javac>
   </target>
   <target name="test" depends="compile">
      <junit>
         <classpath refid="classpath.test" />
         <formatter type="brief" usefile="false" />
         <test name="TestMessageUtil" />
      </junit>
   </target>
</project>

运行下列的 ant 命令

C:\JUNIT_WORKSPACE\TestJunitWithAnt>ant

验证输出。
