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 | 导出 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 |
附加字符串 ;%ANT_HOME\bin to the end of the system variable, Path. |
| Linux | 导出 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 |
| /* |
| * 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; |
| } |
| } |
| 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()); |
| } |
| } |
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。
