-- How this works:
-- register_test registers a test with a name and function
-- The function should return if the test passes or otherwise cause a Lua error
-- The basic structure is: get areas + do operations + check results
-- Helpers:
-- area.get must be used to retrieve areas that can be operated on (these will be cleared before each test)
-- check.filled / check.not_filled can be used to check the result
-- area.margin + check.filled2 is useful to make sure nodes weren't placed too far
-- place_pattern + check.pattern is useful to test ops that operate on existing data
