You don’t really want to use transitive - thats just there for backwards compatibility. By default your app_tree is included in your deps, and since 1.4 Elixir has started your deps for you so they are all in your app tree. :ex_unit won’t be added though. If you want to dialyze in MIX_ENV=test you need to either add ignores for those lines, or add ex_unit separately using dialyzer: [plt_add_apps: [:ex_unit]]
