Task1：Develop the project “HelloWorld”
-A .java program: Just print out “Hello” + your name;
-A test case using Junit to verify whether the program works well.
a:A .java program: Just print out “Hello” + your name:
Code:
package spm;
public class Hello {
public String cassie(){
return "Hello Cassie";
}
public static void main(String[] args) {
Hello cassie = new Hello();
System.out.println(cassie.cassie());
return;
}
}
Screenshot:
b:A test case using Junit to verify whether the program works well:
Click the right button on the package"spm"—>build path—>add libraries—>junit
Then create junit test case
Code:
package spm;
import static org.junit.Assert.*;
import junit.framework.TestCase;
import org.junit.Test;
public class HelloTest extends TestCase{
public void test(){
Hello testHello = new Hello();
assertEquals("Hello Cassie",testHello.cassie());
}
}
Then run it

Task2:Install Maven and Build the “HelloWorld” Project
-Create the directories as “Convention Over Configuration".
-Use “compile, test, package” to build the project.
a:Create the directories as “Convention Over Configuration":
I install Maven and set environmental variables by looking into relevant passages online. After that I check whether Maven is installed in my laptop.

b:Use “compile, test, package” to build the project:
File—>New—>Other—>Maven—>Maven Project
In the App.java:
code:
package Sap.SapCassie;
//import spm.Hello;
/**
* Hello world!
*
*/
public class App
{
public String cassie(){
return "Hello Cassie";
}
public static void main(String[] args) {
App cassie = new App();
System.out.println(cassie.cassie());
return;
}
}
In the AppTest.java:
code:
package Sap.SapCassie;
//import spm.Hello;
import junit.framework.Test;
import junit.framework.TestCase;
import junit.framework.TestSuite;
/**
* Unit test for simple App.
*/
public class AppTest
extends TestCase
{
/**
* Create the test case
*
* @param testName name of the test case
*/
public AppTest( String testName )
{
super( testName );
}
/**
* @return the suite of tests being tested
*/
public static Test suite()
{
return new TestSuite( AppTest.class );
}
/**
* Rigourous Test :-)
*/
public void testApp()
{
assertTrue( true );
}
public void test(){
App testHello = new App();
assertEquals("Hello Cassie",testHello.cassie());
}
}
Run the project:
