I’m trying to mock ExTwitter during tests, I’m using https://github.com/plataformatec/mox for that.
In my code I use a config variable to do the Dependency Injection, like this:
config :my_app, # DI twitter_client: MyApp.TwitterClient
I’ve defined my mock in
test/support/mocks.ex as per Mox docs like this
Mox.defmock(MyApp.Mocks.TwitterClient, for: MyApp.TwitterClient)
and in my
test.exs config I have
config :my_app, # DI twitter_client: MyApp.Mocks.TwitterClient
Everything worked while incrementally compiling during development, however on a fresh checkout without any
_build folder i get this error:
== Compilation error in file test/support/mocks.ex == ** (ArgumentError) module MyApp.TwitterClient is not available, please pass an existing module to :for lib/mox.ex:92: Mox.validate_behaviour!/1 lib/mox.ex:84: Mox.defmock/2 (elixir) lib/kernel/parallel_compiler.ex:121: anonymous fn/4 in Kernel.ParallelCompiler.spawn_compilers/1
if I remove that mock line, compile and add the line back everything works. It seems like it’s trying to compile the mock file first and then the
["lib", "test/support", "test/factories"] so
lib comes first, any idea?
I’ve pushed a sample app with the problem in https://github.com/alex88/myapp just run
