## Project: Testing Practice

This project is a practice exercise for Test Driven Development (TDD) using **Jest** in JavaScript. For comprehensive details on this project, please refer to [The Odin Project - Project: Testing Practice](https://www.theodinproject.com/lessons/node-path-javascript-testing-practice).

## Key Project Instructions:

Write tests for the following functions and ensure that all tests pass.

### Functions To Test

- `capitalize`:


  Capitalizes the first letter of a string.

- `reverseString`:


  Reverses the order of a string.

- `calculator` **object** containing the following methods:

  - `add`

  - `subtract`

  - `divide`

  - `multiply`

- `caesarCipher`:


  Takes a string and a shift factor, returning an encrypted ("shifted") version of the string.

  


  **Requirements:**


  1. The alphabet should wrap around according to the shift factor, e.g., **caesarCipher('xyz', 3)** should return **'abc'**.

  2. The case of each letter should remain the same as in the original string, e.g., **caesarCipher('HeLLo', 3)** should return **'KhOOr'**.

  3. Punctuation and other special characters should remain unchanged, e.g., **caesarCipher('Hello, World!', 3)** should return **'Khoor, Zruog!'**.

- `analyzeArray`:


  TTakes an array of numbers as a parameter and returns an object containing the `average`, `min`, `max`, `length` of the array.
