SPM——Using Maven+Junit to test Hello Wudi

　　Last week, ours teacher taught us 'Software Delivery and Build Management'. And in this class, our teachers gave us a task about Develop the project “HelloWorld” and Install Maven and Build the “HelloWorld” Project. So I want to write something about using Maven and Junit.

　　1.Download Maven and configure environment variables

　　

　　MAVEN_HOME: D:\apache-maven-3.3.1-bin\apache-maven-3.3.1

　　MAVEN: %MAVEN_HOME%\bin

　　PATH:%MAVEN%;

　　Then use cmd command 'mvn -v' to check the environment variables.

　　

　　2.Using maven create your own project

　　

　　After running this command, you will find that in the directory of C:/user/Anonymous, you have created your own project.

　　my-app-simple
　　|-- pom.xml
　　　　`-- src
　　　　|-- main
　　　　|   `-- java
　　　　|       `-- com
　　　　|           `-- mycompany
　　　　|               `-- app
　　　　|                   `-- App.java
　　　　`-- test
　　　　   `-- java
　　　　      `-- com
                     `-- mycompany
                        `-- app
                            `-- AppTest.java

　　3.Compile, test and package

　　

　　This is compile command.

　　

　　

　　This is test command.

　　

　　

　　This is package command.

　　4.Import your project into Eclipse

　　

　　Window->Preferences->Maven->Installations

　　Then add your maven into the Eclipse.

　　Import->Others->Maven->Existing Maven Projects

　　

　　

　　

　　5.Download Junit and configure it

　　

　　6.Write your own project code and test code

　　In App.java

　　

package com.mycompany.app;

/**
 * Hello world!
 *
 */
public class App 
{
	public String sayApp() { 
		return "Hello Wudi!"; 
	} 
	
	
    public static void main( String[] args )
    {
    	App app = new App();
        System.out.println( "Hello Wudi!" );
    }
}

　　In AppTest.java

package com.mycompany.app;

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()
    {
    	
    	App app = new com.mycompany.app.App(); 
    	assertEquals("Hello Wudi!", app.sayApp() );
    }
}

　　Then you can run your project and get what you want.

　　

　　

　　That's all.

　　To be professional.
