The feature for using alternate divisors (other than 3 and 5) does not work

[jawwad]

Note: This is an exercise for the Forking Workflow chapter of the RayWenderlich Mastering Git Book

In 85ca623 a feature was added to allow divisors other than 3 and 5 to be used for Fizz and Buzz. However, this feature does not work since the parameters added to the method signature were not actually used anywhere in the code.

In the following block of code lines 6 and 8 were the ones that were added. However, lines 11 and 12 were never updated to actually use these new parameters. The 3 in line 11 should have been updated to use fizz_divisor and the 5 in line 12 should have been updated to use buzz_divisor.

The following test was added as part of the same commit but it looks like the test may not have been run since it is currently failing.

I receive the following output if I run the tests via python test_fizzbuzz.py. Instead of printing Fizz for 7, Buzz for 11 and FizzBuzz for 77 it just prints the numbers:

test_divisible_by_both (__main__.TestFizzBuzz) ... ok
test_divisible_by_five (__main__.TestFizzBuzz) ... ok
test_divisible_by_none (__main__.TestFizzBuzz) ... ok
test_divisible_by_three (__main__.TestFizzBuzz) ... ok
test_with_alternate_divisors (__main__.TestFizzBuzz) ... test_with_alternate_words (__main__.TestFizzBuzz) ... ok
