Mars Rover Kata (Java)

Goal

Practice Classicist TDD (state verification, no mocks) and familiarize with common code smells, refactoring steps, design patterns and principles.

Develop an api that moves a rover around on a grid.

You are given the initial starting point (x, y) of a rover and the direction (North, South, East, West) it is facing.
The rover receives a list of commands.
Implement commands that move the rover forward / backward.
Implement commands that turn the rover left / right.
Make sure rover doesn't move if it receives an unknown command
Implement wrapping from one edge of the grid to another. (planets are spheres after all)
Implement obstacle detection before each move to a new square.

Sample api:

Rover rover = new Rover(0, 0, 'N');
rover.move("FFBLFR")

Recommended approach to solve this kata is by using TDD.
