Hi 🙂 I'm trying to use

consumerVersionSelectors

from the

PactBroker

annotation on my provider application, and I have a doubt. Looking into the VersionSelector code, it only allows you to select tags, not branches or environments. I think what I would need is to get the latest from the main branch (

master

) and the latest from production. My question is, even if I'm using

branches

and

environments

, should I also add tags from my consumer for both branches and environments?

What is Pact Publish mvn command for Maven Pact library 4.1.33/4.2.19/4.3.4? Looks like it needs this https://github.com/pact-foundation/pact_broker/blob/master/lib/pact_broker/doc/views/index/publish-contracts.markdown. Pact Maven Plugin configuration is <plugin> <groupId>au.com.dius.pact.provider</groupId> <artifactId>maven</artifactId> <version>4.2.19</version> <configuration> <pactBrokerUrl>${pact.broker.url}</pactBrokerUrl> <pactBrokerToken>${pact.pactbroker.token}</pactBrokerToken> <latest>true</latest> <projectVersion>${pact.consumer.version}</projectVersion> <tags>${pact.tag}</tags> </configuration> </plugin> Currently mvn command I am using is "mvn pact:publish -Dpact.consumer.version=<Git Commit> -Dpact.tags=feature-XXX _Dpact.broker.url=<pactbrokerurl> -Dpact.broker.token=${token}. But i am getting error such as [Error] Response from Pact Broker was not in JSON format: au.com.dius.pact.core.json.JsonException: Invalid JSON (1:2), found unexpected character 'U' Failed - Request to path 'https://pactbrokerurl/contracts/publish' failed with response 'HTTP/1.1 401 Unauthorized' But the same mvn command works fine with plugin version au.com.dius.pact.providermaven4.2.9. Currently I am not enabling branches. Could you please share what is the mvn command for publish pacts when using version au.com.dius.pact.providermaven4.2.19 ?

Hi all, thanks in advance for the help! I am trying to debug a test that is failing and don't manage to print the request that the mock is receiving, I really feel like the issue is related to this. What I have tried is to set this property to true but no suceed: pact.showFullDiff .. any ideas? Thanks!

Hi all, I have a couple of questions regarding the verification stage using Java and JUnit5. 1. I am having trouble with setting @IgnoreNoPactsToVerify in the test file (or -DfailIfNoPactsFound=false in the mvn command). With no consumer the test is still failing (context is being set to null). 2. I want to run the verify step against a given environment using the specified 'tag' (we still haven't moved across to environments / deployments). This tag though depends on which CI job is running (ie which environment is being deployed to). Thus I want to pass in the consumer version at run time - and cannot thus set it up in the PACTBroker consumerVersionSelectors annotation. Is there a way this can be passed in maven similar to setting -Dpact.verifier.publishResults=true ? So I can run as part of the mvn command from gitlab CI? Thanks

Hi, do we have any samples for java contracts using graphql apis? The samples I’ve found so far are all Javascript.

Hi Guys, I am trying to do a POC, writing pact test for services consuming and publishing AVRO messages to kafka, I have searched similar discussion that have already happened on this channel, I found this page created for json/json schema registry messages, does pact support AVRO or its still a work in process at this point? cc @Matt (pactflow.io / pact-js / pact-go) @Yousaf Nabi (pactflow.io) @Andy Muir

Hi team, is there any document which introduces how message level contract work in pact? For example, I saw a blog mentioned that "Pact will pretend to be a message queue and get the message provider to send it a message." How does pact pretend to be a message queue?

Hello, I hope this message finds you well. I observing a weird behaviour and I am not sure what I doing wrong. I am using

Copy code

testImplementation('au.com.dius.pact:consumer:4.3.9')
testImplementation('au.com.dius.pact.consumer:junit:4.3.9'

And creating two interactions for the same consumer and provider (one POST and other PUT). I am setting the same response header for both of the interactions but the second interaction, the

response.headers

are being generated different from what I am setting it. I am setting

responseHeaders.put("Content-Type", "application/json; charset=utf-8");

. The first interaction, the header is

"Content-Type": "application/json; charset=utf-8",

but in the second it is

"Content-Type": "application/json;charset=utf-8"

the difference being that the second there is no space after the

. I added another header just for testing and in the second interaction it added an

at the end. Basically, I want that the space in

"application/json; charset=utf-8"

is not removed in second interaction. Do you what can I do to achieve this? I am not sure if I am doing something wrong or is some kind of bug. (code and image in the thread)

Hey, I hope I didn't over read it somewhere, but is there a possibility to annotate one provider test with 2 or multiple consumers? The use case is I have a provider with several consumers, two of them have the exactly same contract, because they are using the endpoints in the exact same way. Currently I have to create 2 identically provider tests classes with the only difference that in one class I have `@Conumser("consumer1")`` and in the other

@Consumer("consumer2")

. Is there another way?

Hi I am working with a java service team, that wants to know if they can run the verify step with mvn test, instead of bringing up the entire service in localhost

bstyle killa

is it mandatory to bring up the real service localhost for the provider verify step

Hi team, how to perform an exact match for message pact, like: now it seems like pact will only verify the type of the field rather than the exact value.

Copy code

PactDslJsonBody body = new PactDslJsonBody();
 body.stringType("name", "almost-anything");

Good morning (evening, afternoon) 👋 We're on pact v3. I've got an issue with NumberTypeMatcher where the matcher does not recognise a negative number as Integer. The part of generated contract file (from MessageBuilder) that fails:

Copy code

$.event_details.net_amount=MatchingRuleGroup(rules=[NumberTypeMatcher(numberType=INTEGER)]

The error I get:

BodyMismatch(expected=-8000, actual=-8000, mismatch=Expected -8000 (JsonPrimitive) to be an integer

Hello, is there a flag or variable we can pass into the jvm build in order to completely avoid the pact tests for the providers?

Robert

Hey, I have a question about verifying contracts on branches. I have a consumer branch A and a provider branch X. I would like to verify now that provider branch X works with the new contract on consumer branch A. I already checked the options: • Have the same branch name for provider and consumer --> That's not a possible option for me • Use the consumerVersionSelectors --> I'm using already "branches" and would need to implement this workaround. https://pact-foundation.slack.com/archives/C9UN99H24/p1654611672907539 OR stepping back and use tags again. My question now, is there any other option?

Hi, My application calls a.o. a few file download endpoints that should be covered by consumer driven contract tests. I don't care about the downloaded content but want to verify that the body is not empty by checking that the Content-Length header is set to a value > 0. Used version: au.com.dius.pact.consumerjunit4.3.10 Consumer code:

Copy code

@Override
protected RequestResponsePact createPact(final PactDslWithProvider aBuilder)
{
  final Map<String, String> requestHeaders = ChatTestUtil.createRequestHeaderMap();

  return aBuilder//
    .given("A text prod finished successfully")//
    .uponReceiving("A request to download text")//
    .pathFromProviderState("/textresult/${jobId}", "/textresult/" + ChatTestUtil.DUMMY_JOB_ID)//
    .method("GET")//
    .headers(requestHeaders)
    .willRespondWith()//
    .status(200)//
    .headers(Map.of("Content-Type", "text/plain"))//
    .matchHeader("Content-Length", "[1-9][0-9]+")//
    .body(PactDslRootValue.stringType())
  //.body(PactDslRootValue.stringMatcher(".*", "whatever"))
  //.withBinaryData("FooBar".getBytes(), "text/plain")
    .toPact();
  }

The variant with "*.body(PactDslRootValue.stringType())*" fails with following exception on provider side:

Copy code

java.lang.AssertionError: 
	Failures:

	1) Verifying a pact between Core_Chat_Client and Chat_Service - A request to download text

		1.1) BodyMismatch: / BodyMismatch: Expected body 'string' to match 'Participants:

The variant with "*.body(PactDslRootValue.stringMatcher(".*", "whatever")*" fails with also on provider side:

	' using regex '.*' but did not match

And the last variant "*.withBinaryData("FooBar".getBytes(), "text/plain")*" fails also:

Copy code

	Failures:

	' using equality but did not match

How can I verify that the body of a response is not empty?

Can we use can-i-deploy without the tags in java?

bstyle killa

07/06/2022, 5:55 PM

https://docs.pactflow.io/docs/workshops/ci-cd/workshop/prerequisite-concepts INFO As of July 2021, recording deployments using the

record-deployment

command has just been released, and support for the corresponding selector

{ deployed: true }

has not yet been added to all the Pact client libraries. The previous method of recording releases was to use tags. If you are not using one of the libraries that currently supports the

{ deployed: true}

selector (currently Javscript and Ruby support it), you will need to use tags in the meantime as per the documentation in the Tags page.

How can you run the @AllowOverridePactUrl for pact-jvm in localhost. We are doing this and its not working

Copy code
