Introduction and clarifications

* In the first challenge I decided to follow the next steps for completing.

• I normalized all the objects for having the same structure on all the objects.
• I populated the missing values with <empty> value.
• I sorted the values for the key.
• I showed the information with Symfony console.

* In the second challenge I decided to follow the next steps for completing.

• I normalized all the objects for having the same structure on all the objects.
• I populated the missing values with <empty> value.
• I built a custom quickSort algorithm to organize the information based on the provided keys.
• I showed the information with Symfony console.

* In the third challenge I decided to follow the next steps for completing.

• I used and populated a SQlite database for saving the information.
• I built some services to build bussinnes logic.
• I built repositories to access the information from the database.
• I build models to represent the information got from the database.
• I used the EcommerceCommand for managing all the logic via console.

Requirements

• Docker
• Docker Compose

Start the project

Execute

  docker compose up -d

This will build a container with sourcetoad name

This container uses Php 8.1, xdebug, composer and other extensions for the project.

Install dependencies

Enter inside the container:

  docker exec -it sourcetoad bash
  cd sourcetoad

Inside the container execute:

  composer install

How Works the features.

I decided to take an approach based on the console for execution. I'm using the Laravel Prompts package to build interactive console commands.

The app starts in the 'bin' folder when I built a simple console app that begins with the following command inside the app folder:

  bin/console 

Console output:

How execute the commands

Enter inside the container

  docker exec -it sourcetoad bash
  cd sourcetoad

Database commands

* This resets the database for cleaning all the base data for the third challenge

  bin/console database:reset

* This populates the database for the firts execution for the third challenge

  bin/console database:first-time

Challenge commands

* This prints the information on a table.

  bin/console challenge:first

* This order the data for the keys provided (you should select on execution)

  bin/console challenge:second

In that example I chosen via Laravel promts what is the key that I want to order In this case I select to organice via Guest Id and Last name

* This order the data for the keys provided (you should select on execution)

  bin/console challenge:third

- menu

- list users

- show cart by customer

a

- checkout review

- checkout

- review orders by user

Unit Test

Enter inside the container

  docker exec -it sourcetoad bash
  cd sourcetoad

Executing the unit test suite

  composer test

Executing the unit test suite with coverage

  composer test-coverage

Executing the unit test suite with coverage and generates a html file for checking in a visual way

  composer test-coverage-html

This last command will generate a new folder that have all the files for checking what part of the code has or not coverage.

Challenge ->

Note: Simple console output is acceptable and desired for the below questions.

Question 1

Given the following example data structure. Write a single function to print out all its nested key value pairs at any level for easy display to the user.

Question 2

Given the above example data structure again. Write a PHP function/method to sort the data structure based on a key OR keys regardless of what level it or they occur within the data structure (i.e. sort by last_name AND sort by account_id). HINT: Recursion is your friend.

Question 3

Given:

• An item contains the following properties:

  • id
  • name
  • quantity
  • price

• A customer contains the following properties:

  • first_name
  • last_name
  • Addresses

• An address contains the following properties:

  • line_1
  • line_2
  • city
  • state
  • zip

• An instance of a cart can have only one customer and multiple items.

• A tax rate of 7%

• Access to shipping rate api (no need to find a working one, simply assume the methods exist elsewhere in the system and access them as you will)

Question:

Please write two or more classes that allow for the setting and retrieval of the following information:

• Customer Name
• Customer Addresses
• Items in Cart
• Where Order Ships
• Cost of item in cart, including shipping and tax
• Subtotal and total for all items
