Starting a new thread because I messed the last one up. Pact broker retrieves the wrong provider version - meaning it retrieves not the latest version. Here is my issue: The consumer, which pushed-pacts, got verified by a provider with version

1.0.0

. The provider has made some application changes and performed a

record-deployment

with version

1.0.1

. The consumer has also made some changes, pushed-pacts, and triggered a provider verification pipeline. The provider verification pipeline has finished successfully, but no indication of verification results are present in the broker, unless I hard-code the previous provider version (

1.0.0

- not latest) in the verification pipeline, that was used to verify the previous consumer version and retrigger the verification process - then the pact broker does receive the results. When I set the log level to DEBUG, I am can see the pact broker client's logs only if I use version

1.0.0

! When I use

1.0.1

I don't see any pact broker client logs🤯 I am using pact-broker version

2.105.0

. Other then

record-deployment

, is there any other action I should be taking in order to update a provider's contract version? Thanks

Hello everyone, everything good? Is there an example of contract versioning anywhere? because I'm having the following problem, there are developers making contracts in different branches and when trying to publish I'm getting the error below, I would like to know how to get around this:

Cannot change the content of the pact for subscription version 1.0 and provider subscription, as race conditions will cause unreliable results for can-i-deploy. Each pact must be published with a unique consumer version number. Some Pact libraries generate random data when a concrete value for a type matcher is not specified, and this can cause the contract to mutate - ensure you have given example values for all type matchers. For more information see <https://docs.pact.io/go/versioning>

Hi, I am exploring Pact for our reactJS to springboot/Java application. Can someone please help me with this issue.Some problems were found with the configuration of task ':pactVerify_test_provider' (type 'PactVerificationTask'). - In plugin 'au.com.dius.pact' type 'au.com.dius.pact.provider.gradle.PactVerificationTask' property 'providerToVerify' is missing an input or output annotation.

Hi, I am trying here to build a sample project for an error I have, but now I run into another error I do not understand. It has to do with LocalDateTime. In my sample Project theoretically it should all work fine (shown as it is at the moment), but I run into the error:

Copy code

1) Verifying a pact between Consumer-Working and provider - consumer-test has a matching body

    1.1) body: $.lastResponse Expected [2021,5,10,16,40,55] to match a datetime of 'yyyy-MM-dd'T'HH:mm:ss': Unable to parse the date: [2021,5,10,16,40,55]

I did try to reproduce a local closed source project, so maybe I forgot to copy something over? At least the LocalDateTime String method here looks very odd (

[2021,5,10,16,40,55]

) In my other error message with our service it shows up as

2021-05-10T16:40:55

Anybody an idea what I am missing? 🙂

Hi, I'm using gradle pactVerify plugin to verify pact and publish the results on the provider side. Plugin version is 4.3.10. Using Java 17 and Gradle 7.6. I'm able to verify and publish the results normally.

Hello, I've got a PR where I'm trying to run a messaging pact test

ConnectorQueueMessageContractTest

. When I run it I get

Copy code

Verifying a pact between connector and adminusers
  a service archived event
      Verification Failed - No annotated methods were found for interaction 'a service archived event'. You need to provide a method annotated with @PactVerifyProvider("a service archived event") that returns the message contents.

But the

@PactVerifyProvider

is clearly there! 😞 I know I'm not on the latest pact-jvm version but hopefully someone here will know what's happening. I've followed the guide at https://github.com/pact-foundation/pact-jvm/tree/master/provider/junit#example-of-message-test

Hello, I encounter a problem when I try to apply request body ( Multipart/form-data entity, Content - Type ) in pact ( consumer side ), when I debug I see MimeMultipart.class get boundary, but when read the file line in parsebm(), outside while loop, line becomes null, thus it won't be able to proceed to the next line of code in parsebm(), the pact failed. Not sure anybody knows how to fix it?

For the problem I encounter, I have already found out the reason: the MultipartEntityBuilder we used in our project is not the same as pact lib's MultipartEntityBuilder, I use pact's MultipartEntityBuilder to make a builder, then the debug passed

Hey everyone! Pasting my question from the general channel, as I was told this is more of a syntax question. I hope someone can help! I have a consumer contract test where I want to reflect that we expect an array with at least one element containing a boolean with value true. From the forums and docs, I understand I can use "*arrayContaining*" to reflect this. I have two questions regarding this: • I actually want to say we want only one element to have this boolean true, all other elements must have it as false. But I believe this is not possible to reflect? • The bigger problem, is that I don't know how to use this "arrayContaining" in the DSL, while it seems to only be possible on arrays contained within an object. The event structure we are consuming is however containing an array on top level, so no parent object. And it is this array which has this requirement.

Hi team, I had an issue with a service that was both a provider and consumer, verification tests would not get called once pact broker triggered them. Once I had removed the consumer dependency it got back to work. Is this something known? Should I exclude anything to avoid this behaviour? Thanks

Hello! I was looking into this page https://docs.pact.io/implementation_guides/jvm/provider/gradle#using-consumer-version-selectors-4310, but couldn't get my configurations to work. Here is a sample of my configurations:

Copy code

plugins {
    java
    id("org.springframework.boot") version "2.7.14"
    id("io.spring.dependency-management") version "1.0.15.RELEASE"
    id("au.com.dius.pact") version "4.6.3"
}

buildscript {
    repositories {
        maven {
            url = uri("<https://plugins.gradle.org/m2/>")
        }
    }
    dependencies {
        classpath("au.com.dius.pact.provider:gradle:4.6.3")
    }
}

pact {
    serviceProviders {
        myProvider {
            fromPactBroker {
                withSelectors {
                    branch("test")
                }
            }
        }
    }
}

However, it is failing to recognize the tokens

myProvider

fromPactBroker

withSelectors

, and

branch

, eventhough it is the exact example from the docs. Can you please help pointing out the issue?

I have a question about grpc/protobuf consumer tests and headers. I tried adding them via the

metadata

key in the map representing the request but that didn’t have any effect. If I don’t specify any headers, then the headers sent by the client don’t get recorded in the pact, and then this one can’t be verified. These are mostly for auth purposes, and I understand we should leave auth out of it, but I’m also curious: with grpc tests, is it possible to set/record headers in the pacts?

Martin Gallauner

Hi there, are there any best practices about how to structure your contract test files? Initially I started by creating one class having all

@Pacts

and

@Test

for the client class but that appears a bit untidy by now. Any second thoughts about having a class for each pact?

Hello! We are trying to implement contract testing with a Java + Springboot + Gradle service as our consumer. While trying to run the tests, I ran into this error:

}

....

I still get the above error. Am I doing it wrong?
