Mars Rover Kata

This code is a part of the Java Tutorial Through Katas: Mars Rover article published on Technology Conversations article.

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 (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 from one edge of the grid to another. (planets are spheres after all)
• 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 and reports the obstacle.

Implementation

Recommended approach to solve this kata is by using TDD. Code in this repo is written in Java 7 with AssertJ for tests. Tasks execution (compile, test, etc) is done with Gradle.

Running

To run all tests:

gradle test
