Hi, we are facing many issues with writing the contracts and making it work because the DSL is quite intuitive when writing the contracts but they dont work straight forward as one would expect and we need to be changing things closeObject(), closeArray() .. and so on ... so the question is .. is there a way to see in a json format what the mock is expecting based on a defined contract? Thanks a lot in advance

Hi, all, I have a question about pact Gradle plugin, 4.1.39 version in use. I am wondering, how can I change some content of pact file that coming from Pactflow broker? We have endpoints, where user id changes instantly, so we decided to keep placeholder in pact file, like

path/to/endpoint/userId/12345

and then replace it on the fly. When storing pact file locally, we used to use

sed

for replacing placeholder with actual id, like

sed s/12345/$ACTUAL_USERID/g

, but it’s not the case when switching to pact broker. Could this be done via

requestFilter

from plugin or somehow else? I know it’s not the best practice, but we need some workaround for now

Hi all, I hope you all are doing fine. We are currently moving the JDK 17, and we faced a strange problem. We cannot debug tests using pact provider and consumer junit5 dependencies. I tried many versions and faced the same problem. I debugged this problem by excluding each library that pact dependency is using, and in the end, I found the problematic area. If I use the below configuration, the problem disappears.

If I do not exclude any of these libraries, I am facing the below problem when I debug the tests in IntelliJ. This happens only for debugging, not running the tests.

Hello - we're introducing Pact across several teams. One of the teams is using Pact .NET exclusively, and it's my understanding Pact-net provider tests only work with V3 Pactfiles. Is there a way to make a pact-junit5 consumer test generate V3 pacts?

Hello. I have a question about

arrayContaining

. I need this logic for an array that is not defined as a value of an object property. Instead, the array is returned as the body of the response.

[
  {....},
  {....}
]

Ideally, I would need a

newJsonArrayContaining

method in

LambdaDsl

. See an example below.

return logAndReturn(builder.given("multiple connections exists")
				.uponReceiving("request to get all connections")
				.method("GET")
				.path("/connections")
				.headers(headers())
				.willRespondWith()
				.status(200)
				.headers(headers())
				.body(newJsonArrayContaining(arr -> {
					......
					});
				}).build()));

As I understand it, there is currently no way to use

arrayContaining

in this situation. Is my understanding correct?

Hello. I am migrating from

4.3.17

to

4.4.4

since I would like to use the V4 Pact specifications. My response is in JSON format and only contains a UUID. See below a valid JSON response.

"08f7a210-95db-4827-bcc8-d2025ba506cf"

I am using the following code to define the interaction:

...
.willRespondWith()
.status(201)
.headers(headers())
.body(PactDslJsonRootValue.uuid(JOB_ID)));

With

4.3.17

, using a Pact v3 contract, the generated contract looks like:

"response": {
        "body": "\"08f7a210-95db-4827-bcc8-d2025ba506cf\"",
        .....
}

With

4.4.4

, using a Pact v4 contract, it looks like:

"response": {
        "body": {
          "content": "08f7a210-95db-4827-bcc8-d2025ba506cf",
          "contentType": "application/json",
          "encoded": false
        },
.....
}

The content value is not a valid JSON value in the case of

4.4.4

. For this reason, the contract cannot be verified by the provider (also using pact-jvm

4.4.4

). See the exception below. This is expected since

"08f7a210-95db-4827-bcc8-d2025ba506cf"

is not a valid JSON document whereas

"\"08f7a210-95db-4827-bcc8-d2025ba506cf\""

is.

1.1) Invalid JSON (1:5), found unexpected character '7'

Am I doing something wrong? If I modify the contract manually as illustrated below, the provider can successfully verify it. Is there a way to generate the response below using the Pact DSL?

"response": {
  "body": {
    "content": "\"08f7a210-95db-4827-bcc8-d2025ba506cf\"",
    "contentType": "application/json",
    "encoded": false
  },

Thanks in advance!

Hi, I am running pact tests using gradle plugin

4.1.39

, using Pactflow as a pact broker. There is a several consumers for same provider, and I can run verification for all consumers using similar config:

fromPactBroker {
   withSelectors {
      selector('tagConsumer1', true, null, 'Consumer1')
      selector('tagConsumer2', true, null, 'Consumer2')
   }
}

via command `./gradlew pactVerify -Ppact.verifier.publishResults=true -Dpact.provider.branch=

git branch --show-current

-Dpact.provider.tag=`git branch --show-current`` How can I run verification for only one specified consumer?

Hi, I am learning the pact-jvm framework by rewriting some of our existing wiremock tests. I’ve noticed that in our wiremock tests, multiple services are mocked in a single test. So in pact-jvm terms, that would be a multiprovider test: https://docs.pact.io/implementation_guides/jvm/consumer/junit5#using-multiple-providers-in-a-test-425. Ive followed the instructions and I get the test running, however I’ve ran into problems when defining mock provider ports in case a multiprovider test. I assume that you have to run a different instance of mockserver for each provider, so that each provider will have their own contract. By default a random port is used for each mockserver instance launched during a test. However our application is configured to call the provider by a fixed port. In case of a single provider test, this would be resolved using “port = 1234” in the @PactTestFor annotation:

@Test
@PactTestFor(providerName = "provider1", port = "1234")
public void example(MockServer provider1mock) {
    ...
}

However, when I do this in a multiprovider test:

@Test
@PactTestFor(pactMethods = {"createProvider1Pact", "createProvider2Pact"}, port = "1234")
public void example(@ForProvider("provider1") MockServer provider1mock, @ForProvider("provider2") MockServer provider2mock) {
   ...
}

I get an “address already in used” exception. Which is logical since I instantiate 2 instances of mockserver, and only provide 1 port. It tries to launch both on the same port. However I have found no way of specifying which mockserver should use which port. Is there a way to do this? I could not find anything in the documentation or source code, though I am unfamiliar with kotlin, I may have missed something. I tried making a subclass of MockServer and set the port myself, but then I ran into injection/instantiation issues with my new class. Alternatively, i have also not found a way to let the application use whatever random port is chosen for the mock.

Hi all, Is the JDK 17 (LTS) version supported? https://github.com/pact-foundation/pact-jvm#supported-jdk-and-specification-versions We cannot see the JDK 17 support on this page. We are moving from JDK 11 to JDK 17, and we would like to know if anyone has faced any issues with JDK 17?

Hi, how to hit the actual api and generate contract instead of mock url for testing

Hi team 😎 🖖, I'm new with pact jvm; one question, the implementation with the local pact broker works for me. Do you know of any guide to publish my contracts in pact flow?

x-posting from #C5F4KFKR8 because of pact-jvm; tl;dr: I'm writing a consumer test that on retrieval of an entity with ID

ID

it checks that the ID of the returned entity matches

however it's not quite working for me (code examples in the thread)

any thoughts/advice much appreciated

final comment: if I relax the checks in the consumer (e.g. I check that the ID is any UUID) then the pact is verified no bother at all

Release - 4.4.5 New release published by rholshausen Bugfix Release • 8c965dc - fix(regression): Changes for #1641 broke the use of plugin mock servers • f4d0171 - feat: support JSON encoded bodies with V4 Pact files • 3e63af6 - fix: correct how the bodies are presisted as per the spec #1658 • 4c74ef9 - fix: correctly decode Pact files with JSON string contents #1658 pact-foundation/pact-jvm

Hi, I am bit new to pact. I have a pact junit5 consumer test using 4.1.7 version and the moment I updrade to latest version - it throws error saying Method (pact method name) does not conform required method signature pact.core.model.V4Pact xxx (PactBuilder builder) Note: until pact junit5 consumer 4.2.21 - test works fine. How can I fix it with later junit5 consumer version ? Thanks

how does one effectively use

valueFromProviderState

in responses? I'm struggling to figure out how this work. The test I have in mind is a consumer saying "when I GET /entity/1 I expect a response like {id: 1}" for instance, where

1

in the path matches the

1

in the response (I already have

pathFromProviderState

working fine)

this is the relevant bit in my consumer test:

body.valueFromProviderState(
                                                                "basketId",
                                                                "basketId",
                                                                existingBasketId.toString())

however in my pact file I end up with

"matchingRules": {
          "body": {
            "$.basketId": {
              "combine": "AND",
              "matchers": [
                {
                  "match": "type"
                }
              ]
            },

and the provider test fails with

1.1) body: $.basketId Expected "698c7e00-1e27-436e-a2e6-f7dd94ea98a7" to be null

this is the state method for the provider test:

Map liveBasketExists(Map _ignored_params) {
        Map<String, Object> state = new HashMap<>();

        InternalBasket internalBasket =
                repository.createBasket(TestSupport.Repository.basketWithDefaults()).orElseThrow();

        // the key in this state-map corresponds to the variable in the expression in the consumer
        // test, i.e. in the
        // example consumer test we have a call like .pathFromProviderState("/${basketId}", ...)
        state.put("basketId", internalBasket.getBasketId());

        return state;
    }

Hello team 😎, I am doing some tests from the consumer trying to generate the contract, it works perfectly for me, but when I want to add headers, it seems the mock response with a 500 error, do you have any idea what could be happening?

hi there, is there a way to define PactDslWithProvided builder with optional arrays ? { "data": { "titles": [ { "titleId": "1234", "parenttitleId": "5678", "titleName": "test", "titleOwner": "xyzb", "titleArchitect": "abcde", "titleLeads": [ //optional array -- how to mention this - if exist - example to be of this type , if not - ignore the verification { "lead1": "xyz", "isEndorsed": true }, { "lead2": "abcd", "isEndorsed": false } ] }, { "titleId": "12345", "parenttitleId": "5678", "titleName": "test", "titleOwner": "xyzba", "titleArchitect": "abcdef" } ] } }

Hi 🙂 When using Pact Juni5 Consumer, is it possible to configure an external mock-server instead of the "in process" one? Thanks

hello everyone. It seems that the PactBroker attributes

scheme

,

host

,

port

are deprecated, but the documentation doesn't explicitly say what replaced them. I do see a

url

, Can any of you please confirm if

url

replaces the other 3?
