Are there any examples of writing Provider tests for Asynchronous/Message based providers that don't use Junit? I can't use Junit and have everything working up to this point, struggling to get this working and all the examples I've found are annotation based.

You can use the standalone verifier, but you will need to setup an HTTP proxy server to return the messages.

Thanks, was able to get what I needed setting the verification type to
