not a kata issue

Then come to the gitter channel mentioned by @XRFXLP, it should be much easier to explain there.

@xlpy You said you;ve read docs, but I am not sure which ones. Have you seen this tutorial?

.

Nope, I can't see your kata because you've not published it yet.

There's nothing fancy with decorators, just use them "above"(basically the preceeding line) the functions which you want to run.

Kinda like:

@test.it("Test suite description")
def i_want_to_run_the_code_inside_this_function():
  expected_solution = reference_solution(...)
  user_solution = solve(...)
  test.assert_equals(..., ...)

How hard it can be?

Can you be more precise?

In anycase, you can ask it here: https://gitter.im/Codewars/codewars.com/kata-authoring-help
