JUnit 与 Ant 集成

我们将通过一个示例演示如何使用 Ant 运行 JUnit。请按照以下步骤操作。

步骤 1：下载 Apache Ant

根据您的操作系统下载 Apache Ant。

步骤 2：设置 Ant 环境

设置 **ANT_HOME** 环境变量，使其指向 Ant 库在您计算机上的基本目录位置。假设 Ant 库存储在 apache-ant-1.8.4 文件夹中。

将 Ant 编译器位置添加到系统路径，如下所示：

步骤 3：下载 JUnit 压缩包

下载适合您操作系统的 JUnit 压缩包。

步骤 4：创建项目结构

• 在 C:\>JUNIT_WORKSPACE 中创建一个文件夹 **TestJunitWithAnt**。

• 在 C:\>JUNIT_WORKSPACE>TestJunitWithAnt 中创建一个文件夹 **src**。

• 在 C:\>JUNIT_WORKSPACE>TestJunitWithAnt 中创建一个文件夹 **test**。

• 在 C:\>JUNIT_WORKSPACE>TestJunitWithAnt 中创建一个文件夹 **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());
   }
}

将 junit-4.10.jar 复制到 C:\>JUNIT_WORKSPACE>TestJunitWithAnt>lib 文件夹。

创建 Ant Build.xml 文件

我们将使用 Ant 中的 **** 任务来执行 JUnit 测试用例。

<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>

运行以下 Ant 命令。

C:\JUNIT_WORKSPACE\TestJunitWithAnt>ant

验证输出。
