Your game will challenge players to drive a Mars rover from one location to another while avoiding hazards. The rover takes three type of instructions L,R and M. ' L ' and ' R ' rotate the rover in the left and right direction. Be creative to make the game your own. Determine how the mission will be deemed a success (the rover reaches the target) or a failure (the rover collides with a hazard). ", //For testing before i set the position of the rover in the middle of the grid. Recall that in TDD, you write the test for a given behavior before you code the //Bonus3: Add validation so that the inputs must be f, b, r, or l, "Only this commands are possible: l, r, b or f".
