%%% Description:
%%% Test suite for common_test which tests the userconfig functionality
%%%-------------------------------------------------------------------
-module(config_dynamic_SUITE).
-compile(export_all).
-include_lib("common_test/include/ct.hrl").
%% This suite will be run with dynamic userconfig
%% test_driver.erl is compliant to ct_config_* callback
%% and test_server is simple server for getting runtime-changing data
%% which will return the list with the following variables:
%% localtime = the erlang:localtime() result in list [{date, Date}, {time, Time}]
%% node = erlang:node() - can be compared in the testcase
%% now = erlang:now() - easier to compare than localtime()
%% config_server_pid - pid of the config server, should NOT change!
%% config_server_vsn - .19
%% config_server_iteration - a number of iteration config_server's loop done
%% disappearable_variable - hereAmI - will be absent on even iterations
suite() ->
[
{timetrap, {seconds,10}}
