Pending interactions in pact-jvm

[holomekc]

Hi, I found this issue pact-foundation/pact-specification/issues/73 and I was wondering how I can set this in pact-jvm. I could find that the model contains the value: https://github.com/pact-foundation/pact-jvm/blob/bb4010b01146eb05f3efc0602fdf0f99719b5c80/core/model/src/main/kotlin/au/com/dius/pact/core/model/V4Pact.kt#L139 But I am not sure how I can set this in my consumer test. I searched in the @Pact annotation and also via the PactDslWithProvider, which we are using to define our expectations. But I could not find a way to do so.

What is the appropriate way to set this pending state?

Br, Chris

PS: Is there a documentation regarding this value? I can only find the pending pacts docs, but nothing regarding pending interactions set by the consumer.

If you use the PactBuilder class, and one of the expectsToReceive methods (i.e. expectsToReceiveHttpInteraction), the child builders have a method to set the pending flag.

For example:

.expectsToReceiveHttpInteraction("V4 PactProviderTest test interaction", httpBuilder -> {
        return httpBuilder
          .withRequest(requestBuilder -> requestBuilder
            .path("/")
            .method("GET"))
          .willRespondWith(responseBuilder -> responseBuilder
            .status(200)
            .body("{\"responsetest\": true, \"version\": \"v3\"}")
            .header("test", notEmpty("Example"))
          )
          .pending(true); // <---
      })

Thx for the incredible fast feedback. This works. Thank you so much.

Hi Sorry to reopen this again. The PactBuilder indicates that PactDslWithProvider and MessagePactBuilder are legacy, but the SynchronousMessagePactBuilder is not? https://github.com/pact-foundation/pact-jvm/blob/a91598b74742771b3cff4f7f3b4a6b5dbed97cc9/consumer/src/main/kotlin/au/com/dius/pact/consumer/dsl/PactBuilder.kt#L82-L101

But then how to achieve the same with Async? I can use the PactBuilder and set the pending flag, but then I am facing issues with creating the content of my expectations.

I could find: /**

• Configure the interaction using a builder supplied by the plugin author. */ fun with(builder: PluginInteractionBuilder): PactBuilder { require(currentInteraction != null) { "'with' must be preceded by 'expectsToReceive'" } return with(builder.build()) } But there seems to be no provided PactInteractionBuilder for Async.

The other option is: https://github.com/pact-foundation/pact-jvm/blob/a91598b74742771b3cff4f7f3b4a6b5dbed97cc9/consumer/src/main/kotlin/au/com/dius/pact/consumer/dsl/PactBuilder.kt#L246-L255

but then I would need to guess message.contents and write alle matching rules as text. https://github.com/pact-foundation/pact-jvm/blob/a91598b74742771b3cff4f7f3b4a6b5dbed97cc9/consumer/src/main/kotlin/au/com/dius/pact/consumer/dsl/PactBuilder.kt#L268-L282

Is there a way to use a builder here and not just a map?

I've added the missing methods to SynchronousMessagePactBuilder.

You can also use PactBuilder.expectsToReceiveSynchronousMessageInteraction which works in the same way as the other interaction builders.
