Robot Factory
This kata is about enabling a user to custom build a robot according their needs. They can configure various parts when designing the robot. The parts are provided by suppliers with whom integration is done via web services. This is because your company, believing fully in lean manufacturing, does not keep stock of any items.
Parts will be supplied by one or more supplies at various prices; you need to make sure the customer gets the cheapest matching part.
The Robot Manufacturing Agreement of 2020 ensures parts from different suppliers are interchangeable with each other.
When building a robot, a user must configure the following parts:
| Part | Options |
|---|---|
| Head | Standard Vision, Infrared Vision, Night Vision |
| Body | Square, Round, Triangular, Rectangular |
| Arms | Hands, Pinchers, Boxing Gloves |
| Movement | Wheels, Legs, Tracks |
| Power | Solar, Rechargeable Battery, Biomass |
The user must make a selection for each part type when building the robot.
You must use the parts as specified above.
Not all suppliers will carry every part.
You must use at least 3 parts suppliers.
Do not worry about a UI - think more api integration.
There are two key methods to implement for this kata:
- Cost Robot
- Queries the various suppliers to find the lowest cost parts as specified and returns the parts with the total.
- Purchase Robot
- Purchases the parts from the respective suppliers
Hint
Use test doubles to check the behaviors you expect along the way - it helps debug the larger test.
