  JUnit - 与 ANT 插件

  • 简述

    我们将有一个示例来演示如何使用 ANT 运行 JUnit。按照下面给出的步骤操作。

  • 第 1 步：下载 Apache Ant

    根据您使用的操作系统下载Apache Ant。
    os 压缩包名称
    windows apache-ant-1.8.4-bin.zip
    Linux apache-ant-1.8.4-bin.tar.gz
    苹果电脑 apache-ant-1.8.4-bin.tar.gz

  • 第二步：设置 Ant 环境

    设置 ANT_HOME环境变量指向基本目录位置，ANT 库存储在您的机器上。让我们假设 Ant 库存储在文件夹 apache-ant-1.8.4 中。
    序号 操作系统和描述
    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 附加字符串 %ANT_HOME\bin 在系统变量的末尾， Path.
    Linux 导出路径 = $PATH:$ANT_HOME/bin/
    苹果电脑 不需要

  • 第 3 步：下载 JUnit 压缩包

    下载适合您的操作系统的 JUnit 压缩包。
    os 压缩包名称
    windows junit4.10.jar
    Linux junit4.10.jar
    苹果电脑 junit4.10.jar

  • 第 4 步：创建项目结构

    • 创建文件夹 TestJunitWithAnt 在 C:\>JUNIT_WORKSPACE 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 中。
    • 创建 MessageUtil C:\>JUNIT_WORKSPACE>TestJunitWithAnt> srcfolder 中的类。 
    
/*
* 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;
   }   
}
    创建 TestMessageUtil 文件夹 C:\>JUNIT_WORKSPACE>TestJunitWithAnt>src 中的类。 
    
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 复制到文件夹 C:\>JUNIT_WORKSPACE>TestJunitWithAnt>lib。

  • 创建 ANT Build.xml

    我们将使用 <junit> Ant 中的任务来执行我们的 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。
