Anyways, this is a shortest path problem, which means this is a duplicate to many existing katas. For example, https://www.codewars.com/kata/57658bfa28ed87ecfa00058a

Mutating the input breaks the random tests: see this

Done

also change assertion messages as per this update.

Grid size for random tests has been decreased to 25*25. Runtime is now 1600ms.

I agree, I'll decrease the grid size right now

The test suite should not take a long time to run (currently it takes almost 9 seconds). Read more here

Just fixed that, thanks

The example from the description must be included as a fixed test in both basic and attempt tests.

Thanks a lot for finding this, just a weird mistake - you are not missing anything!

I must be missing something:

It takes 5 steps to get to the egg (2 steps to the right and 3 steps upwards) and 10 steps to deliver the egg to the chicken (8 steps to the right and 7 steps upwards). So, the total is 15 steps.

How do 8 steps to the right and 7 steps upwards take 10 steps?

Sorry about that, all fixed.

Random tests should not print things for the user, especially not printing the expected value before user solution is run.

Will change this tomorrow, you are definitely correct. I initially chose dictionary because I was considering adding more properties to the chicken and eggs.

Issue is resolved (:
