-- Test cases for generating dependencies between ASTs nodes.
--
-- The dependencies are used for fined-grained incremental checking and
-- the daemon mode.
--
-- The output of each test case includes the dependency map for whitelisted
-- modules (includes the main module and the modules 'pkg' and 'pkg.mod' at
-- least).
--
-- Dependencies are formatted as "<trigger> -> affected locations".
--
-- Look at the docstring of mypy.server.deps for an explanation of
-- how fine-grained dependencies are represented.
