Test files outside test folder

Questions / Help

I would like to put test files alongside the actual code/file that will be tested.

Is it possible? If yes, how can I setup this?

Example:

lib/kv.ex
lib/kv_test.exs

Take a look at https://hexdocs.pm/mix/Mix.Tasks.Test.html#module-configuration

Especially the option test_path.

@NobbZ many thanks!

Just to keep it extremally clear for someone facing the same challenge in the future, what you need to do is:

1) Go to the file mix.exs and add test_paths: ["lib"] in the project function.

Example:

def project do
  [
    app: :kv,
    version: "0.1.0",
    elixir: "~> 1.5",
    start_permanent: Mix.env == :prod,
    test_paths: ["lib"],
    deps: deps()
  ]
end

2) Put the test_helper.exs file inside the lib folder

3) Now you can create all your test files inside the lib folder :thumbsup:
