Backend Developer Challenge

This is a simple challenge to test your skills on building APIs and your logic. It has to be done using Python and Django/Django Rest Framework

What to do

Create a Rest API that controls a car maintenance status, and the trips it performs. Note that, each litre of gas can run 8 KM and every 3 KM the tyres degrades by 1%.

Objects:

• Tyre -- Should have its degradation status in %
• Car -- Should have 4 tyres -- Should have its total gas capacity in liter -- Should have its current gas count in %

Actions:

• Trip -- Input: car, distance (in KM) -- Output: Complete car status on trip end

• Refuel -- Input: car, gas quantity (in Litre) -- Output: Final car gas count in %

• Maintenance -- Input: car, part to replace -- Output: Complete car status

• CreateCar -- Input: None -- Output: Complete car status

• GetCarStatus -- Input: car -- Output: Complete car status

• CreateTyre -- Input: car -- Output: The created tyre

Restrictions:

• The car should NOT have more than 4 tyres in use
• The car should NOT be refueled before it has less than 5% gas on tank
• A car's tyre should NOT be swapped before it hits more than 94% degradation
• A tyre should NOT be created while there is 4 usable tyres with less than 95% degradation
• The car cannot travel without gas or one of its tyres

Challenge

• Write an algorithm in the form of UnitTest that runs a trip of 10.000 KM, without breaking any part or swapping cars or gets out of gas.
• Document your project, with instructions on how to setup and run a working example.

Recommendations

• SOLID / DRY
• Code and Commits in english (methods, classes, variables, etc)

Evaluation

• Project Structure, architecturing and organization
• Logic
• VCS Practices

Delivery

You must fork this repository and commit the solution in the solution folder. Your repository must be public. After that, sand the repository link by email to [email protected]
