Feel free to add the tests cases you think are needed.

If that's all your function does, then it's not complete, that only controls the walk takes 10 minutes, not where you end up.

Which language?

some randome tests gone wrong, i check few they should give other result for example
's', 'e', 'e', 'n', 'n', 's', 'e', 'w', 'n', 's' should give False as i checked, function gave False, but test shown this incorrect,anyway it was funny, i tryed with class and tests on myown pycharm, it was good practice.
s: 0 -1
e: 1 -1
e: 2 -1
n: 2 0
n: 2 1
s: 2 0
e: 3 0
w: 2 0
n: 2 1
s: 2 0
final: 2 0
Walk was not so perfect

in example, looks, like some randome tests not works correctly
