This application allows a customer or hotel employee to calculate the cheapest hotel to stay during specified dates.

The application is divided in three folders:

• doc: containing images that compose this documentation
• hotel_system: main folder with the application files
  • __init__.py: package directory definition
  • __main__.py: contains the main() function that will solve the problem
  • customer.py: class that represents a Customer
  • file_handler.py: file with auxiliary methods to handle the input files
  • hotel_chain.py: class that represents a HotelChain
  • hotel.py: class that represents a Hotel
  • reservation.py: class that represents a Reservation
• tests: folder with the tests written and some test files

The solution was designed considering OO programming principles. There are four classes in the design:

• Hotel: represents a hotel in the system
• Customer: represents a customer in the system
• Reservation: represents a reservation that a customer could make for a specific hotel
• HotelChain: represents a chain of multiple hotels

The picture above shows the class diagram with all attributes and methods for each class:

To run the application with a specific file:

make run FILE=/path/to/file/

To run all the tests:

make test

To clean the executables:

make clean

The figure above shows some test examples running with this solution. These test files are in the path tests/test_files

There are 19 automatized tests written for this application. To run them use the command make test
