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:
下载 Apache ANT
操作系统 | 文件名 |
---|---|
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 |
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。
操作系统 | 输出 |
---|---|
Windows | 在 C:\Program Files\Apache Software Foundation\apache-ant-1.8.4 中设置环境变量 ANT_HOME |
Linux | export ANT_HOME=/usr/local/\apache-ant-1.8.4 |
Mac | export ANT_HOME=/Library/\apache-ant-1.8.4 |
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:
操作系统 | 输出 |
---|---|
Windows | 在 Path 变量值最后添加字符串 ;%ANT_HOME\bin |
Linux | export PATH=$PATH:$ANT_HOME/bin/ |
Mac | 不需要 |
操作系统 | 输出 |
---|---|
Windows | junit4.10.jar |
Linux | junit4.10.jar |
Mac | junit4.10.jar |
MessageUtil
/* * 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。
TestMessageUtil
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。
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。
