setup_test!(module, args)
Generate boiler plate to blackbox-test a grain.
This helper starts a supervised setup to test a "Grain under Test" (GuT):
Publisher ---> GuT ---> Subscriber
By publishing messages through the Publisher
, GuT can be blackbox-tested:
the Subscriber
forwards all messages to the process that called setup_test!/2
.
Use push_into_test/2
to publish a message to GuT.
Arguments
module
: The module of the GuTargs
: The arguments to initialize a GuT
