TDD kata

Mars Rover kata

This is a kata to develop a mars rover application via TDD

Requirements

• You are given the initial starting point (x,y) of a rover and the direction (N,S,E,W) it is facing.
• The rover receives a character array of commands.
• Implement commands that move the rover forward/backward (f,b).
• Implement commands that turn the rover left/right (l,r).
• Implement wrapping at edges. But be careful, planets are spheres.
• Implement obstacle detection before each move to a new square. If a given sequence of commands encounters an obstacle, the rover moves up to the last possible point, aborts the sequence and reports the obstacle.

Rules

• Hardcore TDD. No Excuses!
• Change roles (driver, navigator) after each TDD cycle.
• No red phases while refactoring.
• Be careful about edge cases and exceptions. We can not afford to lose a mars rover, just because the developers overlooked a null pointer.

What was accomplished

• The starting point and directions were accomplished.
• Commands can be received and treated.
• The fact that mars is a sphere has been taken into account.

What still needs to be done

• Obstacle detection
