An attempt to implement cab management example with TDD

Problem Statement

Build intercity cab booking system, to be used as admin and booking tool.

1. Register cabs.
2. Onboard various cities where cab services are provided.
3. Change current city (location) of any cab.
4. Change state of any cab. For this you will have to define a state machine for the cab ex: a cab must have at least these two basic states; IDLE and ON_TRIP
5. Book cabs based on their availability at a certain location. In case more than one cab are available , use the following strategy; a. Find out which cab has remained idle the most and assign it. b. In case of clash above, randomly assign any cab

Assumption : a cab once assigned a trip cannot cancel/reject it

Other Details:

Input: a snapshot of all cabs with their metadata and location a List of <Cab_Id, Cab_State, City_Id> In case the Cab_State is ON_TRIP, the City_Id will be indeterminate

Bonus:

a. Provide insights such as for how much time was a cab idle in a given duration ? b. Keep a record of the cab history of each cab. (A cab history could just be a record of what all states a cab has gone through) c. Find cities where the demand for cabs is high and the time when the demand is highest
