Fixably interview assignment

Installation

• Clone the repo

Help for a command

bin/console fixably:orders --help

Usage:
  fixably:orders [<brand>]

Arguments:
  brand                 Brand to fetch [default: "iPhone"]

Tasks

Task 1:

The token fetching is handled in the background, so no separate command for that

Task 2:

The description was slightly vague regarding what statistics to fetch... So I made a simple interpretation:

bin/console fixably:order-status-counts

+----------+-------+
| Status   | Count |
+----------+-------+
| Assigned | 1415  |
| Closed   | 855   |
| Open     | 537   |
| Unpaid   | 223   |
+----------+-------+

Task 3:

bin/console fixably:orders iPhone

Notes

The implementation process went basically so that I created a command and added the necessary methods to the OrderService interface.

Then I wrote a test for the method against the ApiOrderService to verify I get back data in expected format.

As I had access to an API endpoint for testing data I decided not to mock any HTTP calls, though the HttpClient has quite good support for that and I typically have to do it as there is no test endpoints for use.

The token fetching is automated before each API call.

The error handling is very basic, but should handle typical API failures.

src/Command contains the Symfony Console Commands that handle the input/output. Instead of Commands one could very easily implement some Controllers for web page rendering or whatever.

The Commands use only an interface for fetching Domain formatted DTOs

src/Service contains the OrderService interface and one implementation. The interface is very top-level and does not expose any knowledge of the real API.

src/Dto contains the Domain models for communicating with the OrderService interface.
