hmm I’m even finding now that I can’t have more than one test that exercises ModestEx, as I get messages like this error:

21:49:11.600 [error] GenServer ModestEx.Safe.Cnode terminating
** (ArgumentError) all arguments for System.cmd/3 must be binaries
    (elixir) lib/system.ex:782: System.cmd/3

Last message: {:nodedown, :"e5a463a0@127.0.0.1"}

ETA actually, I was incorrect, the second test was just producing a ModestEx error 😬

Hey Buck, looking at the error message this is a nodex issue. Are you able to provide an example to demonstrate this? I would need some time to look at this. Maybe also ask this in the forum. I remember there is a nodex thread here.

Thanks for the response!

I made this repository to reproduce the problem. In e326b53, I added the modest_ex dependency and a simple test to exercise it, and the tests passed.

Then in 418d51c I added a before_script on Travis CI to start the Phoenix server with mix phx.server &, so it’s running in the background. Then the tests don’t run.

However, the error is different than the one I see locally and there are some CMake errors earlier in the log, so it may be that this isn’t a true reproduction. But when I have mix phx.server running locally and run mix test in another terminal, I do get a similar error:

** (Mix) Could not start application modest_ex: exited in: ModestEx.Safe.start(:normal, [])
    ** (EXIT) exited in: :gen_server.call(:boot_server, {:add, {{255, 255, 255, 255}, {127, 0, 0, 1}}})
        ** (EXIT) no process: the process is not alive or there's no process currently associated with the given name, possibly because its application isn't started

I’m experiencing this on macOS 10.14.4. It’s not a disaster as I’ve just been killing the server when I want to run the tests.
