Testing Setup


describe "Solution" do
  it "should test for something" do
    Test.assert_equals("actual", "expected", "This is just an example of how you can write your own TDD tests")
  end
end

The Problem

Test Custom FizzBuzz 

fizz_buzz_custom[15]                         # returns 16
fizz_buzz_custom[44]                         # returns "FizzBuzz" (45 is divisible by 3 and 5)
fizz_buzz_custom('Hey', 'There')[25]         # returns 26
fizz_buzz_custom('Hey', 'There')[11]         # returns "Hey" (12 is divisible by 3)
fizz_buzz_custom("What's ", "up?", 3, 7)[80] # returns "What's " (81 is divisible by 3)

Should I TDD?
