Description

Parking Lot is a simple application that accepts string-based commands to control parking lot system. You can run the application with interactive command prompt based shell or with file that contains commands.

Command List

Basic commands:

• create_parking_lot <PARKING_LOT_SIZE>
• park <CAR_REGISTRATION_NUMBER> <CAR_COLOUR>
• leave <SLOT_NUMBER>
• status
• exit

Query commands:

• registration_numbers_for_cars_with_colour <CAR_COLOUR>
• slot_numbers_for_cars_with_colour <CAR_COLOUR>
• slot_number_for_registration_number <CAR_REGISTRATION_NUMBER>

Illegal Operation

User is assumed to input with correct arguments. For example, leave will exactly accept an integer. Other than that, the system should be able to handle illegal operations such as:

• park when parking lot is full
• leave an already empty slot, or using out-of-range slot number
• create_parking_lot with size lower than 1
• invoking unlisted command
• accessing parking lot (park, status, etc) before successfully invoked create_parking_lot

Build Instruction

Run bin/setup to build the project with dependencies and run tests.

parking_lot $ bin/setup

Run Instruction

Run bin/parking_lot to start the application. It accepts one optional argument for input file path. You should build the project before running the application.

parking_lot $ bin/parking_lot <OPTIONAL_FILE_PATH>

You can also run Rspec-based testing suite by running bin/run_functional_tests.

parking_lot $ bin/run_functional_tests

For more information about the testing suite, see functional_spec.

Development

To develop this project, you will need:

• Java 8 or higher
• Gradle

Additionaly, you will need Ruby to run functional_spec.
