Designing tests for inexact numbers

Please, read the following page for explanation of the design of tests for inexact values:

then consult the tester web page for concrete examples:

To generate random numbers,

  import java.util.Random;

then define field:

  Random RAND = new Random();

then define a method:

  // produce a random number in the range [0, 5)
  int randomNum(){
    return this.RAND.nextInt() % 5;
  }

and use it when you need such number. Adjust this to fit your game design.
