JUnit ：ANT 插件

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

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。
