FizzBuzz is a classic coding kata. Here is a brief summary:\n\nFizzBuzz Kata:\n\nThe FizzBuzz kata is a simple programming task, used in software developer job interviews, to determine whether the job candidate can actually write code. The task is as follows: \n\n- Write a program that prints numbers from 1 to 100. \n- But for multiples of three print \u201cFizz\u201d instead of the number \n- And for the multiples of five print \u201cBuzz\u201d \n- For numbers which are multiples of both three and five print \u201cFizzBuzz\".\n\nLet's start by creating a test for our program. We will use Python and its built-in 'unittest' library for testing. I'll create a new testing file. \n\nNow, I'll create a new Python file called \"test_fizzbuzz.py\" which will contain all of our tests for the FizzBuzz function. \n\nexecute: touch test_fizzbuzz.py"}, {"role": "user", "content": "executeResult {\n  cmd: touch test_fizzbuzz.py\n  output: \n  exit: 0\n}\n---\n"}, {"role": "assistant", "content": "Great, we have created our test file successfully! Now we need to start writing our test cases inside this file.\n\nLet's start by writing a test to check if our program is correctly substituting multiples of 3 with \"Fizz\". For example, for the number 9 the program should return \"Fizz\".\n\nHere is a skeleton of the test function:\n\n```python\nimport unittest\n\nclass TestFizzBuzz(unittest.TestCase):\n\n    def test_multiple_of_three(self):\n    # Our implementation goes here\n        pass\n```\n\nI am going to write this skeleton into our test file.\n\nexecute: echo -e \"import unittest\\n\\nclass TestFizzBuzz(unittest.TestCase):\\n\\n    def test_multiple_of_three(self):\\n        # Our implementation goes here\\n        pass\\n\" > test_fizzbuzz.py\n\nAfter that, we will add the assertion logic to ensure our FizzBuzz function behaves as expected."}, {"role": "user", "content": "executeResult {\n  cmd: echo -e \"import unittest\\n\\nclass TestFizzBuzz(unittest.TestCase):\\n\\n    def test_multiple_of_three(self):\\n        # Our implementation goes here\\n        pass\\n\" > test_fizzbuzz.py\n  output: \n  exit: 0\n}\n---\n"}, {"role": "assistant", "content": "Great, our test skeleton is in place.
