Pruebas Unitarias para Practica

Challenge: Jest

Basic info

What is this

• It's just a small excercise
• Focused for unit tests with Jest
• It can be refactored
• It can be optimized

Tech

• Jest
• Jest dependencies
• That's it

Components

• calculator.js and users.js has all main methods to test
• Inside tests directory is where you should write you test cases
• data.js contains an array of user data. This is your data to manipulate.
• You can ignore index.js

Other Components

• Write the named files for each case.

  1. Write a function that takes in a number and returns one of the following:

     • If the number is divisible by 3, return 'Fizz'.
     • If the number is divisible by 5, return 'Buzz'.
     • If the number is divisible by 3 and 5, return 'FizzBuzz'
     • Else, return the number passed as an argument

  2. Write a function that takes in a DNA string (for example 'CTAGGGTA') and returns a new string with any non-canonical DNA base values removed. Canonical base values are single characters: 'C', 'T', 'A', and 'G' only. Make the function case sensitive - meaning 'c' (lower case) should be removed from the string, but 'C' (upper case) is a good value and should remain. If the DNA string is empty, just return an empty string.

  3. Calculate the factorial of a number using recursion
