this computes a fizz buzz sequence. They are really advanced.

var fizzBuzz = require("../src/fizz_buzz");
describe("FizzBuzz", function(){
    it("exists", function(){
        expect(fizzBuzz).toBeDefined();
    });
    
    describe("fizzBuzz.generate(3)", function(){
       var result;
       beforeEach(function(){
          result = fizzBuzz.generate(3) ;
       });
       it("returns [ 1, 2, 'Fizz']", function(){
        expect(result).toEqual([1, 2, "Fizz"]);
       }); 
    })
});
