erros when running tests

[angelo-moreira]

I am trying to run the tests on Ubuntu 18.04 (Bionic) with

# elixir -v
Erlang/OTP 21 [erts-10.0] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1]

Elixir 1.7.1 (compiled with Erlang/OTP 21)

The tests run successfully (it seems) but I am getting a lot of errors, output below:

Any idea what could be causing this?
Thank you for this package, great work.

Hi @angelo-moreira thank you for your comment and kind words.

Yes, the test suite is a bit rough and ready - the errors are completely normal, since we actually test some behaviour that results in an error. One thing to do might be to disable the logger entirely for the test run to avoid confusing people.

Might be a nice first PR for you, if you're interested in something like that.
