2. Step 1: Download Apache Ant
3. Step 2: Set up the Ant environment
4. Step 3: Download Junit Archive
In this example, we'll show you how to run JUnit with ANT. L et's follow these steps:
Download Apache ANT
Operating system | Filename |
---|---|
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 |
Set ANT_HOME environment variables to point to the basic file address stored in the machine by the ANT library. For example, we've stored the ANT library in the apache-ant-1.8.4 folder for different operating systems.
Operating system | Output |
---|---|
Windows |
At the C:\Program Files?Apache Software Foundation
Set the environment variable in .apache-ant-1.8.4 to ANT_HOME |
Linux | Export ANT_HOME ./usr/local/.apache-ant-1.8.4 |
Mac | export ANT_HOME=/Library/\apache-ant-1.8.4 |
Attaching the ANT compiler address to the system path is as follows for different operating systems:
Operating system | Output |
---|---|
Windows |
Additional strings;
%ANT_HOME\bin to the end of the
system variable, Path. |
Linux | Export PATH $PATH: $ANT HOME / bin / |
Mac | No, you don't need to |
Download JUnit Archive
Operating system | Output |
---|---|
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());
}
}
We will use the tasks in ANT to perform our junit test sample.
