Erlang OTP/Test Server, example of test suite

-module(my_SUITE)....

-include("test_server.hrl").

-define(default_timeout, ?t:minutes(1)).

all(suite) -> %% Test specification on test suite level

[not_started_func1].

not_started_func1(suite) -> [];

not_started_func1(doc) ->

["Testing function 1 when application is not started"].

not_started_func1(Config) when list(Config) ->

?line {error, not_started} = myapp:func1(dummy_ref,1),

?line {error, not_started} = myapp:func1(dummy_ref,2),

ok.
