Setting common tests config file not working

[dnldd]

Hi, I'm trying to run a test suite with my existing app config. Going through the erlang.mk options , CT_OPTS seemed like the way to go with this so I did try CT_OPTS = -config debug.config in my makefile. I still can't get access to my config file after doing this. How do you set external config files for common tests with erlang.mk? Thanks.

Like you did. Please post the makefile.

[dnldd]

PROJECT = roadsigns

ERLC_OPTS ?= -Werror +debug_info
+warn_export_all +warn_export_vars
+warn_shadow_vars +warn_obsolete_guard

CT_SUITES = test

CT_OPTS = -config debug.config

DEPS = cowboy emysql jiffy lager erlcloud
dep_cowboy = https://github.com/extend/cowboy.git master
dep_emysql = https://github.com/Eonblast/Emysql.git v0.4.1
dep_jiffy = https://github.com/davisp/jiffy.git 0.8.5
dep_lager = https://github.com/basho/lager.git 2.0.3
dep_erlcloud = https://github.com/gleber/erlcloud.git master

cr:
rm -rf _rel/

cct:
rm -r ./logs

rd: app
if [ -n "${PROJECT}" ]; then erl -pa ebin -pa deps/*/ebin -smp -boot start_sasl ${ERL_ARGS} -config debug.config -name ${PROJECT}@hostname -s ${PROJECT};
else ${RUN} -s ${PROJECT};
fi

include erlang.mk

Yeah it should work. Is your config file in the same directory as the makefile though? You gotta say tests/debug.config if it's in there.

[dnldd]

Yes they are in the same directory. The config has param "roadsigns" in there which I try getting in init_per_group/2 with ct:get_config(roadsigns) and it keeps returning undefined.

[essen]

I think the -config option is for specifying the sys.config file. Can you try with -ct_config instead?

[dnldd]

Yeah just tried it, didn't work either. I must be messing up somewhere else. I'm loading the config just so I can set it as the app env in init_per_group/2. Perhaps I'm going about that wrong.
init_per_group(roadsigns_api, Config) -> RSConfig = ct:get_config(roadsigns), application:ensure_all_started(roadsigns), application:set_env(roadsigns, roadsigns, RSConfig), .

Here is a snippet of the config:
[ { roadsigns, [ { cowboy_port, 8080 }, { cowboy_listeners, 100 }, { emysql_pool_size, 10 }, … ]} ]

Well I don't really know, never used that myself. You'll have better luck on erlang-questions.

[dnldd]

Ok, I'm on it. Will post what I find here. Thanks for the help @essen

[dnldd]

It seems the default config from the app takes precedence over whatever config is set via CT_OPTS. I'm also getting noproc errors for functions that run just fine in the release.

[dnldd]

Finally got it to work, I used CT_OPTS = -erl_args -pa ebin -pa deps/*/ebin -smp -boot start_sasl ${ERL_ARGS} -config ./test/debug.config -name ${PROJECT}@hostname -s ${PROJECT}. Setting the config via erl_args solved it.

CT_OPTS = -erl_args -config test/app.config was sufficient in my case.
