* EXCEPTION:
Failed to eval: []. can't convert Symbol to Integer.
Serialization data may be corrupt.

** Running: test_stuff
I found a test method called :test_stuff. But it needs to have
the following method signature:
#+begin_src
def test_stuff args, assert

end
#+end_src
Please update the method signature to match the code above. If you
did not intend this to be a test method. Rename the method so it does
not start with "test_".
