Robot Factory code challenge

Description

At Robot Factory Inc. we sell configurable Robots, you can configure one for us to manufacture it.

When ordering a robot, a customer must configure the following parts:

• Face (Humanoid, LCD or Steampunk)
• Material (Bioplastic or Metallic)
• Arms (Hands or Grippers)
• Mobility (Wheels, Legs or Tracks)

An order will be valid if it contains one, and only one, part of face, material, arms and mobility.

If an order is valid and there are enough parts to assemble the robot:

• The priced order should be calculated
• The stock must be adjusted to reflect the fact that parts are being used in robot manufacturing.

What to do

Given a stock of:

Code    Price   Available  Part  						
————————————————————————————————————————————————————
A      10.28     9	       Humanoid Face  
B      24.07     7	       LCD Face
C      13.30     0	       Steampunk Face
D      28.94     1	       Arms with Hands
E      12.39     3	       Arms with Grippers
F      30.77     2	       Mobility with Wheels
G      55.13     15	       Mobility with Legs
H      50.00     7	       Mobility with Tracks
I      90.12	 92	       Material Bioplastic
J      82.31	 15	       Material Metallic

Given a list of part codes, implement a robot creation order:

Input HTTP POST /orders { "components": ["I","A","D","F"] }

Output 201 {"order_id": "some-id", "total": 160.11 }

Requirements

• You can use kotlin or java with either gradle (version >= 6.0.1) or maven (version >= 3.6.3). Unfortunately, we can not send a zip with the wrapper because of security reasons
• We are providing a kotlin skeleton with all dependencies and a few acceptance tests to check if the problem is working, but all the code should be fully tested at all levels
• All tests should pass using gradle test or maven test
• Please write clean code
• We are going to look for good design and architecture
• Don't use any database or library to manage persistence, this restriction includes JPA, spring-data, ORMs and any physical database.
• No additional dependencies are allowed on top of those already specified in build.gradle.kts

Have fun!
