🤖 NODE - Martian Robots

The challenge is to create a martian robots simulator.

Sample input:

1 1 E

✅ Robot turns left from any orientation when receives "L" instruction .

✅ Robot turns right from any orientation when receives "R" instruction .

✅ Robot moves forward when receives "F" instruction.

✅ The output indicates the final grid position and orientation of the robot.

✅ If the robot falls off the edge of the grid, the word "LOST" is printed after the position and orientation.

❌ More than one robot.

❌ An instruction to move "off" the world from a grid point from which a robot has been previously lost is ignored by the current robot.

Since it was the first time that I faced this kind of exercise, I took that as an opportunity to keep learning and improving.

This is why I performed the exercise trying to follow TDD methodology:

That allows me to take "baby steps" and detect errors easier and faster, so that I could fix them before the next step.

You need to have either Node or Docker previously installed in your computer.

To start using this project, clone this repo to a new directory.

 $ git clone https://github.com/conchaasensiomr/node-martian-robots.git

You have to go to run npm install in order to install the necesary dependencies.

$ npm install

Finally, to run the tests, you need to introduce the following command on your terminal:

$ npm test

⚠️ Should you are a MacOS user, please note that this process might be a bit slow. Take it into account if you are using Docker on a MAC computer.

In case you are using Docker, first of all you need to write the following command on your terminal:

$ docker-compose run martian-robots npm install

Finally, to run the tests, you need to introduce the following command on your terminal:

$ docker-compose run martian-robots npm test
