Hi Nathan! The issue is that the compiler is just one of many ways where we can define modules in Elixir. Maybe you expected this module to be define in your test_helper and you have a type in the module name. The module could also have come from a dependency and you had a typo in its name when using it.
I think ultimately pointing towards elixirc_paths would be misleading. *José Valimwww.plataformatec.com.br <http://www.plataformatec.com.br/>Founder and Director of R&D* On Wed, May 9, 2018 at 11:25 PM, Nathan Long <[email protected]> wrote: > I just added a `test/support` directory and `test/support/data_case.ex` to > my Mix application.
