From c3391bb822f0516975b293bc220e1a44cdb8bc0c Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Jos=C3=A9=20Valim?= Date: Wed, 9 Jan 2019 12:24:17 +0100 Subject: Add start_distribution to kernel environment Sometimes you may want to start Erlang without any of its distribution services. This commit adds an environment configuration that allows so. Because the servers we don't start here are a subset of the servers not started on minimal mode, we do have a guarantee that the system can still operate as the system operates without those apps on minimal mode. --- lib/kernel/test/kernel_config_SUITE.erl | 21 ++++++++++++++------- 1 file changed, 14 insertions(+), 7 deletions(-) (limited to 'lib/kernel/test') diff --git a/lib/kernel/test/kernel_config_SUITE.erl b/lib/kernel/test/kernel_config_SUITE.erl index 9207025a2c..57c44c2498 100644 --- a/lib/kernel/test/kernel_config_SUITE.erl +++ b/lib/kernel/test/kernel_config_SUITE.erl @@ -21,7 +21,8 @@ -include_lib("common_test/include/ct.hrl"). --export([all/0, suite/0,groups/0,init_per_group/2,end_per_group/2, sync/1]). +-export([all/0, suite/0,groups/0,init_per_group/2,end_per_group/2, + start_distribution_false/1, sync/1]). -export([init_per_suite/1, end_per_suite/1]). @@ -30,7 +31,7 @@ suite() -> {timetrap,{minutes,2}}]. all() -> - [sync]. + [sync, start_distribution_false]. groups() -> []. @@ -59,12 +60,9 @@ from(H, [H | T]) -> T; from(H, [_ | T]) -> from(H, T); from(_, []) -> []. -%%----------------------------------------------------------------- -%% Test suite for sync_nodes.
