`rover-cli`

A coding exercise in controlling a set of rovers on mars.

🛠 Installation

sh cargo install rover-cli

🔋 Usage

Print output to console:

sh rover-cli foo.txt

Save output to file: sh rover-cli --output output.txt foo.txt

To see helpful information:

sh rover-cli --help

💭 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:

sh 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.
