JUnit - Plug with Ant 介绍

我们将通过一个示例演示如何使用ANT运行JUnit。请遵循以下步骤。

步骤1:下载Apache Ant

根据您正在使用的操作系统,下载 Apache Ant

OS存档名称
Windows apache-ant-1.8.4-bin.zip
Linux apache-ant-1.8.4-bin.tar.gz
Mac apache-ant-1.8.4-bin.tar.gz

步骤2:设定Ant环境

将 ANT_HOME 环境变量设置为指向基本目录位置,该目录在您的计算机上存储ANT库。让我们假设Ant库存储在apache-ant-1.8.4文件夹中。

Sr.No.OS & Description
1

Windows

将环境变量ANT_HOME设置为C:\Program Files \Apache Software Foundation \apache-ant-1.8.4

2

Linux

导出ANT_HOME = /usr/local/apache-ant-1.8.4

3

Mac

导出ANT_HOME = /Library/apache-ant-1.8.4

将Ant编译器位置附加到系统路径,如下所示-

OS输出
Windows在系统变量 Path 的末尾附加字符串%ANT_HOME \bin 。
Linux导出PATH = $ PATH:$ ANT_HOME/bin/
Mac不需要

步骤3:下载JUnit存档

下载适合您的操作系统的JUnit存档。

OS存档名称
Windows junit4.10.jar
Linux junit4.10.jar
Mac junit4.10.jar

步骤4:创建项目结构

  • Create a folder TestJunitWithAnt in C:\>JUNIT_WORKSPACE.

  • Create a folder src in C:\>JUNIT_WORKSPACE>TestJunitWithAnt.

  • Create a folder test in C:\>JUNIT_WORKSPACE>TestJunitWithAnt.

  • Create a folder lib in C:\>JUNIT_WORKSPACE>TestJunitWithAnt.

  • Create MessageUtil class in C:\>JUNIT_WORKSPACE>TestJunitWithAnt> srcfolder.

/*
* 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;
   }   
}  	

Create TestMessageUtil class in the folder C:\>JUNIT_WORKSPACE>TestJunitWithAnt>src.

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());
   }
}

Copy junit-4.10.jar onto the folder C:\>JUNIT_WORKSPACE>TestJunitWithAnt>lib.

创建ANT Build.xml

We'll be using <junit> task in Ant to execute our JUnit test cases.

<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>

运行以下Ant命令。

C:\JUNIT_WORKSPACE\TestJunitWithAnt>ant

验证输出。
