POM update to run JUNIT Tests when we do "mvn test"

 Some times:

unit tests in test files under src/test wont run when we do. "mvn test" command

Some observations to check  is:

- Few plugins considers file name is Test

- Practise to name function name prefix or suffix by Test

- Another important thing is maven configuration (For Junit 4) add below info
