@rholshausen just a little more context for the reason why I am looking to switch to the Lamda DSL docs — it’s because as pointed out in the docs, the junit4 DSL seems to be buggy (I’m on version

4.2.20

). We’ve got 2 different similar requests like:

DslPart requestOneResponseBodyDslPart = PactDslJsonArray
                .arrayEachLike()
                    .uuid("id", UUID.randomUUID())
                    .datetime("startTime", INSTANT_FORMAT_STRING)
                    // More keys here
                .closeObject();

DslPart requestTwoResponseBodyDslPart = PactDslJsonArray
                .arrayEachLike()
                    .uuid("id", UUID.randomUUID())
                    .datetime("scheduledStartTime", INSTANT_FORMAT_STRING)
                .closeObject();

Both of them generate random UUIDs and the default datetime string adhering to the format like:

"2000-02-01T00:00:00.000000Z"

in the pact JSON file. The problem is that `requestOneResponseBodyDslPart`’s provider verification is expecting exact value matches for both the

.uuid

and

.datetime

fields, which is really odd, considering we’ve used PactDslJsonArray before too.

Switching to lambda based DSL will not resolve your problems, as it all uses the same implementation. You need to work out the correct values to use in your tests.

Actually, I just spotted that the pact being generated for

requestOneResponseBodyDslPart

doesn’t include any

generators

and

matchingRules

for that request 🤔

How are the DSL parts used (ie. ``requestOneResponseBodyDslPart``)

Like so:

return builder
                .given("MY STATE")
                    .uponReceiving("a request to get all of a participant's recommendations")
                        .path(String.format("/api/participants/%s/recommendations", DEFAULT_PARTICIPANT_ID))
                        .method("GET")
                        .headers(REQUEST_HEADERS_WITH_AUTH)
                    .willRespondWith()
                        .status(200)
                        .headers(RESPONSE_HEADERS_FOR_VALIDATION)
                        .body(getRecommendationsPactDslJsonBody.toString())
.toPact();

Don't do this:

getRecommendationsPactDslJsonBody.toString()

, it converts it to pure JSON and you loose all the matchers and generators. Just remove the

toString()

call

Jeez, thanks heaps!
