Use Junit to test classes
Player and Enemy classes will be Build through a PlayersFactory class. This startegy is based on Factory method design pattern.
Specify classpath files when running javac to find junit and other classes. The separator of -cp flag is ':' in linux and ';' on windows
Use this class to build objects from Player and Enemy classes. Pass 1 through constructor method to Build a Player and other number to build an Enemy
This interface is used to build Player and Enemy objects from PlayersFactory class. Hello method is used to identify if it is a Player or Enemy being build
Player is the rectangle controled by user in the Pong Player game
Enemy is the rectangle controled by computer in the Pong Player game
To run the test classes in command line, you have to specify JUnit JAR file and Hamcrest library JAR file (JUnit depends on it) in the classpath.
Update class to test from command line running 'make test'
Just run a simple test to check if junit-platform is running
Define rules to Makefile to only build test when run 'make test' and to only clean tests when run 'make cleantest'. Now Makefile only build test classes if necessary
Test if the objects Player and Enemy are correctlly build by factory method PlayersFactory.createPongPlayer
Now 'PlayersFactory.createPongPlayer' accepts 'player' or 'enemy' strings to identify which object to build. If a different string is passed, the method throws an 'IllegalArguentException' and returns null. TestPlayersFactory is modified to check for exception case and to pass string parameters
PongPlayer is a interface to be implementes by Player and Enemy classes. Those classes are both rectangles that move on screen. PlayersFactory is a factory class based on factory method design pattern to build PongPlayer objects, Player and Enemy
Game class starts a new game in an infinite loop, every iteration it updates and renderizes the game.
Update Makefile to build Game class and do multiple Junit tests.
Use Thread.sleep method and fps variable to control frames per second tax in main loop of the game
Game class implements main loop of the game in a specific frames per second tax

Description
Simple Game engine built in Game class.
This engine uses the same simple engine example in the Dankicode classes that runs in a while loop with ticks interval controlled by Thread.sleep() method. This method does Thread to sleep for specific time in mile seconds and can be used to control loop iteration velocity (Frames per second).
Game class offers an interface to control FPS, setFPS() method. This tested in TestGameFramesPerSecond class using Junit.
