[erlang-questions] Problems with dynamically compiled eunit test

[Paulo F. Oliveira]

Something similar happened to me recently, while using Cowboy as a
dependency. I had the following in rebar.config:

{erl_opts, [{src_dirs, ["src", "test", ...

which made both my application's and all my dependencies' "src" and "test"
folder be compiled leading to a "module already present/compiled"-like
exception.

I changed rebar.config to:

{erl_opts, [{src_dirs, ["src", "../myapp/test", ...

which, probably not being the best solution, at least solved my problem.

Cheers.
