Mars Rover kata using UML, TDD, Java

UML Class Diagram

All rovers need a plateau to land on, currently only rectangular shaped plateaus are supported.

Enter the maximum x and y coordinates of the plateau, e.g. Creates a 10x10 square with 0,0 coordinate at the bottom left-hand corner On successful creation a plateau id will be returned. Multiple plateaus can be created. Maximum size for a Quad Plateau is 9999999,9999999

To create a rover on the current plateau specify its x and y coordinates and heading, e.g. 0 0 N Creates a rover on the current plateau at coordinates 3,5 with a heading of North Direction. Plateaus can support multiple rovers.

Rover move and spin commends are available to enable exploring: spin left, e.g. if current heading is North, new heading is East spin right move one grid position in the direction of the current heading A single command can contain multiple move and spin instructions, e.g. LLMMMRMMM

SWITCH PLATEAU SWITCH ROVER LIST PLATEAUS LIST ROVERS SHOW MAP HIDE MAP FINISH HELP On exit a report of all rover positions is produced.

Rovers cannot land on or move to the space as another Rover on the same plateau.
On receipt of a move command the rover calculates its new coordinates and validates the move with the plateau. The plateau check the coordinates are within bounds and the position of any other rovers. Two rovers cannot share the same coordinates

The application can run using manual input from the command line or a file containing instructions can be passed as a parameter. Example instruction files are available in the test data folder.
