## Design Checks

# For some checks, you can also set other parameters
#
# If you don't want the `setup` and `test` macro calls in ExUnit tests
# or the `schema` macro in Ecto schemas to trigger DuplicatedCode, just
# set the `excluded_macros` parameter to `[:schema, :setup, :test]`.
#
{Credo.Check.Design.DuplicatedCode, excluded_macros: []},
# You can also customize the exit_status of each check.
# If you don't want TODO comments to cause `mix credo` to fail, just
# set this value to 0 (zero).
