JAVA implementation of the mars-rover code kata. Each class has accompanying unit tests in their respective "spec.js" file located in the "spec" folder. This plateau, which is curiously rectangular, must be navigated by the rovers so that their on-board cameras can get a complete view of the surrounding terrain to send back to Earth. About the images: Hazards are everywhere on Mars and can include rocky terrain, dust devils, and rippled sand dunes, as shown in these images (clockwise from left) taken on and at Mars by the Perseverance rover, Mars Reconnaissance Orbiter, and Curiosity rover, respectively.

So,. Below is a walkthrough of the Test Driven Devlopment of the suite(s) and classes. Develop your skills as a young coder and explore block coding, JavaScript, and Python while . An example position might be 0, 0, N, which means the rover is in the bottom left corner and facing North. Only write the minimum amount of code needed to make the test pass. Jasmine specs are located alongside the modules they're testing, and follow the naming convention *_spec.js. L and R makes the rover spin 90 degrees left or right respectively, without moving from its current spot. This means that the best path is not always the shortest path as we may need to evade treacherous areas or conditions.
