W08H01: Missing Test: solveMazeFrom impossible path from position to exit

[LadnerJonas]

Homework Number: W08H01

Citation of the homework instruction:

static Path solveMazeFrom(Maze maze, Position position):
[....]
Sollte ein solcher Pfad nicht mehr existieren, soll null zurückgegeben werden.

Additional Information:

Maze
[....]
du kannst aber davon ausgehen, dass der exit immer vom entrance aus erreichbar ist.

Position can be != Entrance, and thus, this case has to be tested aswell.

Thanks @mani 🏅

I would agree, the instruction describes what do do with not valid positions for solving the maze. So we need to handle the case of position != entrance. And some test for that would be great!

Also here the link for the zulip post im getting my information from:

Also a test for the case: "going over the entrance" needs to be added i think. Because i think i read that it is possible for a solution path to start somewhere at the top and then cross the entrance on its way down.

In this case P marks the starting point. I think therfore the valid solution should be 4*Dow
Correct me if im wrong

I will try to find the corresponding Zulip Post tomorrow.
I will also try to create a test and upload it by then if i somehow figure out how to do that^^

[LadnerJonas]

Yeah a zulip link would be great. 👍
Just asked the so-called Übungsleitung: This is a valid maze and we need to be able to solve it.

[YannickWiest]

If this still needs to be converted into a test by tomorrow I will do so.

[LadnerJonas]

I am working on it. 🚀

Can be closed @YannickWiest @0xReself?
