Feature: Real time update of Parking Lot occupancy In order to have accurate availability value for a parking lot, occupancy must be updated every time a driver enters a parking lot Scenario: Entering with First Come First Serve access type Given "Brussels Nord" parking lot has 53 available spots When a car enters "Brussels Nord" parking lot using "FCFS" access Then there are 52 available spots in "Brussels Nord" parking lot 1 2 3 4 5 6 7 8
