-- golden test suite
-- | Golden executable tests.
--
-- We test target generation against a golden file in @tests/fixtures/init/@ for
-- executables, libraries, and test targets with the following:
--
-- * Empty flags, non-simple target gen, no special options
-- * Empty flags, simple target gen, no special options
-- * Empty flags, non-simple target gen, with generated comments (no minimal setting)
-- * Empty flags, non-simple target gen, with minimal setting (no generated comments)
-- * Empty flags, non-simple target gen, minimal and generated comments set.
--
-- Additionally, we test whole @.cabal@ file generation for every combination
-- of library, lib + tests, exe, exe + tests, exe + lib, exe + lib + tests
-- and so on against the same options.
