How to test project in Maven ?
- In previous we discuss how to create a Java application using Maven. Now we going to see how to build and test the application.
- Go to C:/MVN directory where you've created your java application. Open consumerBanking folder.You will see the POM.xml file with following contents.

POM.xml
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.companyname.projectgroup</groupId>

<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>3.8.1</version>
</dependency>
</dependencies>
</project>
- Now you can see, Maven already added Junit as test framework.
- By default Maven adds a source file App.java and a test file AppTest.java in its default directory structure discussed in previous chapter.
- Let's open command console, go the C:\MVN\consumerBanking directory and execute the following mvn command.
C:\MVN\consumerBanking>mvn clean package
- Maven will start building the project.

[INFO] ------------------------------------------------------------------------- You've built your project and created final jar file, following are the key learning concepts
- We give maven two goals, first to clean the target directory (clean) and then package the project build output as jar(package).
- Packaged jar is available in consumerBanking\target folder as consumerBanking-1.0-SNAPSHOT.jar.
- Test reports are available in consumerBanking\target\surefire-reports folder.
- Maven compiled source code file(s) and then test source code file(s).
- Then Maven run the test cases.
- Finally Maven created the package.
- Now open command console, go the
- C:\MVN\consumerBanking\target\classes directory and execute the following java command.
C:\MVN\consumerBanking\target\classes>java com.companyname.bank.App

Adding Java Source Files
- Let's see how we can add additional Java files in our project. Open C:\MVN\consumerBanking\src\main\java\com\companyname\bank folder, create Util class in it as Util.java.
maven tutorial tags : apache maven , maven repository , maven central
Util.java
package com.companyname.bank;
public class Util
{
public static void printMessage(String message){
System.out.println(message);
}
}
- Update App class to use Util class.

Sample code
package com.companyname.bank;
/**
* Hello wikitechy!
*
*/
public class App
{
public static void main( String[] args )
{
Util.printMessage("Hello wikitechy!");
}
}
- Now open command console, go the C:\MVN\consumerBanking directory and execute the following mvn command.
C:\MVN\consumerBanking>mvn clean compile
- After Maven build is successful, go the C:\MVN\consumerBanking\target\classes directory and execute the following java command.
C:\MVN\consumerBanking\target\classes>java -cp com.companyname.bank.App
