WDS Remote Code Challenge

This is an exercise, but there is not one right answer. Please do not distribute without permission. This is a deliberately simple project with a few small tasks to complete.

• Should take approximately one to two hours
• Do what seems right to you to complete the work
• Complete as many stories as you can
• Choose an appropriate technology to implement this in
• Should provide a method of proving the effectiveness of the program
• Please manually clone this repository and send us the link to your implementation when finished
• An example "devices.json" file is provided

Story 1

As a DeviceTester

I want to load in a list of devices from a file

So that I can deliver them on request

Acceptance Criteria:

• Load in a list of devices from a file in json format
• Example file provided - "devices.json"
• Return all devices loaded in on demand

---

Story 2

As a DeviceTester

I want to retrieve devices based on full name (BRAND and MODEL)

So that I can return devices more selectively

Acceptance Criteria:

• Devices are loaded from a file (i.e. Story 1)
• Return a device or devices that match a full name (BRAND and MODEL separated by a space)

---

Story 3

As a Device Tester

I want to ensure that my device file is valid

So that I do not see any invalid devices

Acceptance Criteria:

• Validate device based on the following criteria
  • full name (BRAND and MODEL separated by a space) should be unique
  • brand must be filled in - max length 50 characters
  • model must be filled in - max length 50 characters
  • form factor must be one of the following "CANDYBAR", "SMARTPHONE", "PHABLET", "CLAMSHELL"
  • attributes are optional
  • if any attributes are given, they must have a name and a value
  • attribute name max length 20 characters
  • attribute value max length 100 characters
• Only load valid devices from the JSON file
• Log invalid devices

---

Story 4

As a DeviceTester

I want to retrieve devices based on their brand or model name

So that I can return devices more selectively

Acceptance Criteria:

• Return a device or devices that match a brand name
• Return a device or devices that match a model name

---

Question: What would you do to improve things if you had more time? Answer: Think of ways to improve and simplify the validation for story 3.
