Hey there, how do i implement sync & async provider tests (so REST and event based messaging) for the same provider? Currently we get "No test target has been configured for AsynchronousMessage interactions" in the REST Provider Test class. Do we need to set a filter for this class or something?

You can add additional test targets. See https://github.com/pact-foundation/pact-jvm/blob/master/provider/junit5/src/test/j[…]u/com/dius/pact/provider/junit5/CombinedHttpAndMessageTest.java for an example

Okay thanks. A bit of a pitty that this needs to be added even if the test class doesn't run async tests. I've send this to the affected team, but it seems like the ones responsible are out of office. I will try to respond here if this solved the issue, but if I respond nothing, it worked and i just forgot.

Oh, if you don't want to verify the async interactions, then, yes, there is a filter you can use

okay that seems to be exactly the problem. How do I set the filter?

You can filter the interactions by either the description or provider state. The properties to use are

pact.filter.description

and

pact.filter.providerState

In our codebase which uses Junit 5 we implemented our own interaction filters:

public static class Async<I extends Interaction> implements InteractionFilter<I> {
        public Predicate<I> buildPredicate(String[] ignored) {
            return (interaction) -> interaction instanceof V4Interaction.AsynchronousMessage;
        }
    }

    public static class Sync<I extends Interaction> implements InteractionFilter<I> {
        public Predicate<I> buildPredicate(String[] ignored) {
            return (interaction) -> interaction instanceof SynchronousRequestResponse;
        }
    }

By using these in the

@PactFilter

annotation, you can filter for Snyc / Ansyc interactions
