💭 Code Choices

• --unbounded command flag is included to allow to the rover to exit the plateau.
• isize is used to represent co-ordinates to allow the rover to pass (0, 0).
• fs::read_to_string is used for simplicity over the more performant but more complex BufReader.
• RoverControlSatellite is used for themeatic effect!

🔬 Testing

To run tests for the CLI:

cargo test

Testing Approach

Unit tests that cover basic functionality and possible branches are included, however as this is a coding exercise, 100% coverage has not been aimed for.
