Thank you for the help.

This fixes the node naming issue, but unfortunately this not enough to make
it work.

Long story short: in my tests I define some callback functions that need to
be called for the tests to pass.
However, I need to specify the path to the test directory too, because
otherwise my slave node doesn't have these functions defined.

This is how I do the trick now:
(this passes)
(this directory does not exist when I use rebar3).

SO: is there a way to have rebar copy the test directory to:


You may want to try:

This actually works, though I see an "experimental" warning on top and I
cannot really automate it in a script, as there's no `--eval` option in
`rebar shell`.

So I've tried adding a test.escript file:

#!/usr/bin/env escript

main(_) ->


$ rebar3 shell --sname=mynode --script test.escript

"/Users/roberto/workspace/syn/test.escript" - exit:{noproc,






Stack: [{gen_server,call,3,[{file,"gen_server.erl"},{line,212}]},

And I'm stuck.

Any ideas?
