Start dependent application with eunit
- by ruslander
I start lager as a dependent application when I run a unit test but for some reason the code under test does not see it.
-module(main_tests).
-include_lib("eunit/include/eunit.hrl").
main_test_() ->
{foreach,
fun distr_setup/0,
fun distr_cleanup/1,
[
fun must_retain/1
]}.
must_retain(_) ->
{"Should do ping pong when is fully initialized",
fun() ->
?assertEqual(pong, abuse_counter:ping())
end}.
%%------------------------------------------------------------------
distr_setup() ->
abuse_counter:start_link(),
ok.
distr_cleanup(_) ->
abuse_counter:stop(),
ok.
Here is the output of the log which is complaining that lager is not defined
{undef,[{lager,info,["up and running"],[]} though in the run output is definitely there.
Here is how I run it:
erl -pa ebin/ ../../deps/*/ebin -s lager -eval 'eunit:test(main_tests,[verbose]), init:stop().'
Fails with the output
Eshell V5.10.2 (abort with ^G)

Failed: 0. Skipped: 0. Passed: 0.
One or more tests were cancelled.
Already spent 3-4h hours on google and stack overflow but nothing seems to work.
One option is to hide this call behind a ?INFO(Mgs) macro but do not like the idea.
Any help will be highly appreciated.
