The output for each rover should be its final co-ordinates and heading. Rover objects know about their own current direction and coordinates. 'L' and 'R' makes the rover spin 90 degrees left or right respectively, without moving from its current spot. Recall that in TDD, you write the test for a given behavior before you code the An object representing the mars rover. This way, if the input or output ever needs to change, we can just change the interfaces instead of picking through the code for magic strings. decrease.

Write the test and then create the code to make it pass. At this point, we have placed our rover on the Martian terrain and created the hazards it must avoid, but at this point, they are all stationary. Think about ways to refine your game not just in terms of difficulty, but also complexity. This has been created using gradle; to run the tests, just execute: And then execute the app from the subfolder build\libs: This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. Each class has accompanying unit tests in their respective "spec.js" file located in the "spec" folder. It may help to put the rover and the hazards, along with their rules for moving, in one loop, but this can be done across multiple loops or even across multiple libraries. Dictionary for the rovers to reference depending on the direction they are facing: The main function that takes the input and gives the desired output: Functions that parse the input string and prints the output string.
