JUnit - ANT 插件

在這個例子中，我們將展示如何使用 ANT 運行 JUnit。讓我們跟隨以下步驟：

步驟 1:下載 Apache Ant

下載 Apache ANT

步驟 2:設(shè)置 Ant 環(huán)境

設(shè)置 ANT_HOME 環(huán)境變量來指向 ANT 函數(shù)庫在機器中存儲的基本文件地址。例如，我們已經(jīng)在不同的操作系統(tǒng)的 apache-ant-1.8.4 文件夾中存儲了 ANT 函數(shù)庫。

附加 ANT 編譯器地址到系統(tǒng)路徑，對于不同的操作系統(tǒng)來說如下所示：

步驟 3:下載 Junit Archive

下載 JUnit Archive

步驟 4:創(chuàng)建項目結(jié)構(gòu)

• 在 C:\ > JUNIT_WORKSPACE 中創(chuàng)建文件夾 TestJunitWithAnt
• 在 C:\ > JUNIT_WORKSPACE > TestJunitWithAnt 中創(chuàng)建文件夾 src
• 在 C:\ > JUNIT_WORKSPACE > TestJunitWithAnt 中創(chuàng)建文件夾 test
• 在 C:\ > JUNIT_WORKSPACE > TestJunitWithAnt 中創(chuàng)建文件夾 lib
• 在 C:\ > JUNIT_WORKSPACE > TestJunitWithAnt >src 文件夾中創(chuàng)建 MessageUtil 類

/*
* 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 文件夾中創(chuàng)建 TestMessageUtil 類。

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 文件夾中復(fù)制 junit-4.10.jar。

創(chuàng)建 ANT Build.xml

我們將使用 ANT 中的 任務(wù)來執(zhí)行我們的 junit 測試樣例。

<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>

運行下列的 ant 命令

C:\JUNIT_WORKSPACE\TestJunitWithAnt>ant

驗證輸出。
