Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
I don't understood your explanation, sorry!
"the test suite should always contain a test with a following scenario: for example ..., ..., WEST, EAST, WEST, SOUTH
To ensure that when WEST and EAST are removed the next WEST will not be removed because EAST should be already gone"
This remark may correspond to your solution but there are lots of possible solutions and the random tests are ... random.
I don't consider that it is an issue.
