The following sub$13$ function was implemented by someone who is very evil$$it$\text{'}$s supposed to always return $($the input number $13).$ Write a test case using the provided assertTrue function that will discover the error $($i$.$e$.,$ fail$).$ Pretend that your code will replace the "FIXME: YOUR CODE HERE" comment. Do not fix the sub$13$ function$$all I want is a test.
