Mars Rover Kata (Java)

Goal

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

Description

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")

Implementation

Recommended approach to solve this kata is by using TDD.
