Hi all,
a very simple CT test takes forever to boot.
%%%%%% Module %%%%%%%%%
-module(mymodule).
-export([greetings/1]).
greetings(Text) ->
lists:flatten(io_lib:format("~s world!", [Text])).
%%%%%%%%%%%%%%%%%%%%%%%
%%%%%% CT test %%%%%%%%
-module(mymodule_SUITE).
-include_lib("common_test/include/ct.hrl").
-export([all/0]).
-export([greetings_test/1]).
all() ->
[greetings_test].
greetings_test(_Config) ->
"hello world!" = mymodule:greetings("hello"),
"goodbye world!" = mymodule:greetings("goodbye").
%%%%%%%%%%%%%%%%%%%%%%%
Here's the log:

==================
it literally takes 20 seconds before the first (and only) test is run. Any
ideas why?
Thank you,
r.
