Exercises

1 - FizzBuzz

A classic exercise for beginners, one that can show the basics of TDD.

Requirements

1. Create a function called fizzBuzz that takes a number as input and returns it as a string
2. When input is a multiple of 3, return "Fizz" instead of the number
3. When input is a multiple of 4, return "Buzz" instead of the number
4. When input is a multple of both 3 and 4, return "FizzBuzz"

2 - Password validation

Another classic exercise. The function should return a True if the password is valid and False otherwise as well as an error message to help the user.

Requirements

1. The password must be 8 characters long. If not, then the following error message should be returned "Password must be at least 8 character"
2. The password must contain at least 2 numbers. If not, then the following error message should be returned "Password must contain at least 2 numbers"
3. The password must contain at least 1 capital letter. If not, then the following error message should be returned "Password mnust contain at least one capital letter"
4. The password must contain at least 1 special character. If not, then the following message should be returned "Password must contain at least one special character"
5. The function should handle multiple validation errors. If there are multiple errors then the messages of those corresponding errors should all appear in the message.
