JUnit - Collegare con ANT

Avremo un esempio per dimostrare come eseguire JUnit utilizzando ANT. Segui i passaggi indicati di seguito.

Passaggio 1: scarica Apache Ant

Scarica Apache Ant in base al sistema operativo su cui stai lavorando.

OS	Nome archivio
finestre	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

Passaggio 2: impostare l'ambiente Ant

Impostare il ANT_HOMEvariabile di ambiente in modo che punti alla posizione della directory di base, in cui sono archiviate le librerie ANT sulla macchina. Supponiamo che le librerie Ant siano archiviate nella cartella apache-ant-1.8.4.

Sr.No.	Sistema operativo e descrizione
1	Windows Impostare la variabile di ambiente ANT_HOME su C: \ Programmi \ Apache Software Foundation \ apache-ant-1.8.4
2	Linux esportare ANT_HOME = /usr/local/apache-ant-1.8.4
3	Mac esporta ANT_HOME = /Library/apache-ant-1.8.4

Aggiungi la posizione del compilatore Ant al percorso di sistema come segue:

OS	Produzione
finestre	Aggiungi la stringa %ANT_HOME\bin alla fine della variabile di sistema, Path.
Linux	export PATH = $ PATH: $ ANT_HOME / bin /
Mac	non richiesto

Passaggio 3: scarica l'archivio JUnit

Scarica un archivio JUnit adatto al tuo sistema operativo.

OS	Nome archivio
finestre	junit4.10.jar
Linux	junit4.10.jar
Mac	junit4.10.jar

Passaggio 4: creazione della struttura del progetto

Crea una cartella TestJunitWithAnt in C: \> JUNIT_WORKSPACE.
Crea una cartella src in C: \> JUNIT_WORKSPACE> TestJunitWithAnt.
Crea una cartella test in C: \> JUNIT_WORKSPACE> TestJunitWithAnt.
Crea una cartella lib in C: \> JUNIT_WORKSPACE> TestJunitWithAnt.
Creare MessageUtil classe in C: \> JUNIT_WORKSPACE> TestJunitWithAnt> srcfolder.

/*
* 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;
   }   
}

Creare TestMessageUtil class nella cartella C: \> JUNIT_WORKSPACE> TestJunitWithAnt> src.

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());
   }
}

Copia junit-4.10.jar nella cartella C: \> JUNIT_WORKSPACE> TestJunitWithAnt> lib.

Crea ANT Build.xml

Useremo <junit> task in Ant per eseguire i nostri casi di test JUnit.

<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>

Esegui il seguente comando Ant.

C:\JUNIT_WORKSPACE\TestJunitWithAnt>ant
