ExUnit unwanted output

[Elliot Crosby-McCullough]

Hello!

I'm testing some GenServers, specifically testing certain behaviours that deliberately cause the GenServer to terminate itself.

This is all going well, except the test run outputs a notification about the closing process (the GenServer, not the test process) on what I assume is STDERR.  Is there some way to suppress this?

It seems to happen whether I start the genserver via `start_link` and unlink it or create one without linking.

All the best,

Elliot

Hey Elliot

Could you share the printed notification with us please?

Cheers,
Louis

Just use the capture log tag to, well, capture the log:

@tag :capture_log

test "this test will log error stuff" do

You can also set it for the whole suite: ExUnit.start(capture_log: true). If you do so, the log will still be included in error reports.

That did the job, thanks José.  I'd already tried using ExUnit.CaptureIO to no effect, didn't know this tag existed.

Louis, in case you'd still like to know, this was the log output:

07:43:21.560 [error] GenServer #PID<0.99.0> terminating

** (stop) "Closing connection"

Last message: {.. bunch of stuff ..}

State: {%{connection_abort: #Function<3.107869130/1 in ZeroMQ.ConnectionTest.__ex_unit_setup_0/1>, message_delivery: #Function<1.107869130/1 in ZeroMQ.ConnectionTest.__ex_unit_setup_0/1>, peer_delivery: #Function<2.107869130/1 in ZeroMQ.ConnectionTest.__ex_unit_setup_0/1>, security_mechanism: #Function<5.107869130/1 in ZeroMQ.ConnectionTest.__ex_unit_setup_0/1>}, #PID<0.100.0>, {.. closing state ..}}

Thanks both,

Elliot
