    Hi All, I have generated the openapi-generator-cli author default mustache templates, I need to implement pact in mustache templates and generate the client, is there any direct way convert and add pact in mustache templates ? 
    npx openapi-generator-cli author template -g go -o templates-go
    npx openapi-generator-cli generate \
    -i /path/to/openapi-spec.yaml \
    -g go \

    I am encountering an issue while running my provider tests in a Gradle Kotlin Spring Boot project. I have a contract with 10 test cases, and my provider tests are split across two files—one file covers 2 states, while the other handles 8 states. However, when I run my provider tests, the contract checks for all 10 states in each file instead of only the relevant ones. As a result, I get 10 passing tests but also 10 failing tests because each file is validating all the states, leading to incorrect failures. things i have already tried: 1. moving SpringBootTest to base call 2. https://stackoverflow.com/a/79264442 please help ASAP Slack Conversation

    Hello everyone, i was tasked after defining contract testing with messaging pacts in our company to try adding contract testing to on of our C++ projects. But if i look at the repo it seems that there is no support? anymore. Is the current state even able to do provider tests especially with messaging pacts? And what would be a good alternative to go at this problem? Thank you in advance for your time :)

    Thank you to @Yousaf Nabi (pactflow.io), @Tien Vo and the PACT team for sending me a Tee for the participation with Tien on PHP I was helping because I like to explore cool tech and it seemed there was a gap in PACT PHP, which in 2022 I was using for work. It's amazing to see all the improvements made and the group going from success to success!

    Heya, I hope I have the right channel for this. I am trying to introduce (consumer driven) contract testing in our company, and picked a frontend and backend service as a pilot, but I seem to run into a chicken-egg problem, because they are already sharing an openapi spec file between them. And the frontend uses this file to generate the backend calling code. For the sake of example and to test my knowledge, lets forget the existance of the openapi file for a sec, and look at a scenario where the frontend is building a new feature that requires a new endpoint of the backend. If I understand the concept of consumer driven correctly, then it should look something like: 1: Frontend creates a new feature, and add some point during development reaches the point where they require the new backend call to get some data. 2: Frontend creates a new consumer test, in which they stub the backend in a way that they would like to receive the data. 3: When the test passes, a new contract is created containing the new endpoint, and data they expect to receive (the interaction) 4: Frontend pushes the contract to the broker 5: Backend pulls the contract from the broker, provider test fails, and implements the endpoint according to the expected result. 6: Once the provider test passes, both consumer and provider proceed to merging and deploying their changes. First of all, is my understanding so far correct? Now back to the usage of an openapi spec. Where I struggle in this specific case, is that the consumer uses the openapi spec to generate their backend calling code. If it is up to the consumer to write a consumer test first, how can they do that when they depend on the spec file to generate the calling code? The frontend cant write a test without the openapi file, but the backend cant provide the new openapi file without a new contract first. How do you transition from a 'provider first' to a 'consumer first' way of working when they were already sharing openapi file? The only thing I can think of is that the frontend first manually writes some temporary backend calling code, and uses that in the test. New contract is generated and pushed, backend pulls, implements, and sends the new openapi spec back to the frontend, where they then generate the new backend code, and replaces the temporary code with the generated one. But that seems very cumbersome and a very tough sell. When theyre already using openapi, perhaps the most logical answer would be to use bidirectional testing? But we are specifically looking into consumer driven, because we want to do value specific asserts. And bidirectional only does structural asserts right?

    probably a silly question but my team is really struggle with which jobs we need to be running in which context for a provider. 1. we have a webhook trigger job to verify our consumers. this seems to make sense 2. we should have can-i-deploy running in our main pipeline before deployment to make sure that we have an acceptable pact agreement. makes sense 3. branch pipelines with changes going into the main branch (MR/PR) this is where we are stuck a. we had roughly the same trigger pipeline running verifyPacts but this was aparently cause consumers to verify against the wrong version and fail (the branch instead of mainline) b. it seems like we should be able to run can-i-merge but this would require publishing the verification which was causing us issues. would be great to get some clarity on this so we can figure out what exactly it is that we need to fix. i feel i have scoured the documentation quite a bit and everything seems to be in the context of the consumer thinking2

    I’m a bit confused about the way consumer tests work when it comes to multiple interactions. For context, I’m working on a C++ wrapper that uses a pact plugin for a custom transport, in case that matters. When I create a pact and define the interactions in each test case, each time my 
    runTest
    method is called which calls 
    pactffi_create_mock_server_for_transport
    I see the 
    StartMockServer
    method being called on the plugin with the JSON pact only containing the interactions defined up to that point. Now the part I don’t understand is what the mock server is supposed to do here, is it supposed to listen for all of the defined requests? If so, how are you supposed to distinguish between interactions with the same request but with different provider states? Or is the idea that the mock server only responds to the last defined interaction?

    We’re working on using matchers using the 
    pactffi_matches_json_value
    function, and are seeing some unexpected behavior for some more advanced rules where the check passes even though it shouldn’t… For example, with an 
    arrayContains
    matching rule, no error is returned even though an array with one element that doesn’t satisfy the matching rules is passed to it. Here’s the line in the pactffi log for the check:
    Copy code
    2025-03-31T15:16:12.632536Z DEBUG ThreadId(01) pact_matching::json: JSON -> JSON: Comparing '[{"baz":42,"foo":"bar"}]' to '["bla"]' using ArrayContains([(0, MatchingRuleCategory { name: BODY, rules: {DocPath { path_tokens: [Root, Field("baz")], expr: "$.baz" }: RuleList { rules: [Type], rule_logic: And, cascaded: false }} }, {})]) -> Ok(())
    We’re using pactffi release 0.4.26 btw, am I missing something here?

    Hi I would like to know if it is possible to configure Pactflow to automatically assign users to teams upon authentication via SSO, for example, using Azure Active Directory (Azure AD). The goal is for Pactflow to map the groups a user belongs to in the Active Directory (AD) during the login process, and based on that information, automatically assign them to one or more specific teams within the platform. This would allow the appropriate permissions and roles to be applied from the first login, without requiring manual assignments. Is it possible to enable this functionality to map SSO groups to Pactflow teams?

    Hi team, I’m looking for some advice on our current Provider's CI/CD setup with Pact Broker. We have two separate branches: 
    staging
    and 
    production
    , which may contain different code as features are tested in staging before being rolled out to production. 1. Would it make sense to maintain separate sets of Pact stages for each branch? 2. I've observed that when a webhook is triggered, the verification always runs against the main branch (staging), regardless of which branch initiated the process. This could potentially cause issues when the branches diverge. Any suggestions on how we can improve this setup or handle branch-specific verification more effectively? Thanks! Slack Conversation

    Hi. I have a json structure like this:
    Copy code
    {
  "data": [
    {
      "id": "123456789"
    },
    {
      "id": "111111111",
      "optional_stuff": {
        "data_map": {
          "blah_1": true,
          "blah_2": 123456
        }
      }
    }
  ]
}
    So my question is how to write the pact contract such that 
    "id"
    is mandatory but 
    "optional_stuff"
    is optional? At the moment I have to only specify the 
    "id"
    part as it's unclear if pact supports optional data.

    Hi, I'm currently using Pact Python v3, and I'm trying to implement consumer version selectors with a version for a specific consumer. However, I couldn't find any documentation or guides specifically for version 3. Is it possible to add a consumer version selector in this version of Pact Python? Below is the code I’m currently working with:
    Copy code
    verifier = Verifier().set_info(name=PROVIDER_NAME, url=PROVIDER_URL)
verifier.broker_source(url=URL(settings.pact_flow_url), token=settings.pact_broker_token)
verifier.set_state(url=PROVIDER_URL / "_pact" / "callback", teardown=True)
verifier.filter_consumers(consumer_name)
verifier.set_publish_options(version=str(version))
verifier.verify()
    Thanks for your help!

    Hi This is pavanraj from atlassian, we have use-case of asynchronous api, 1. The api accepts the order and responds with 202. 2. Consumer polls on get order, based on the type of order placed, there will be fields set in the response. What is the recommendation for writing contract tests ? How do i get the confidence that any modification in order processing flow would ensure fields are populated as expected for the use-case ?

    👋 Hi everyone!
  • p
    Hi has anyone here ever renamed existing providers ? or has anyone ever provided providers that have no consumers ? So we have a microservice and therefore pacts were moved there. To know which contract belongs to whom we have changed the names. Unfortunately, I can no longer deploy or I can't do a can-i-deploy because there are no consumers or they simply still listen to the old providers. I wanted to ask how you deal with this?
  • p
    I should mention that the consumers are in other teams so I can't change them so easily

    Hello everyone, is there a recommended way to deal with Branches in Tag Pipelines? The GitLab Tag Pipelines have no branch name set. From what I have come up with I have two options: 1. Use the default branch name (which the tags are always made on). Then in validation pipelines that are triggered by webhooks I can check that out and reset to the tag. 2. Use no branch name. In webhook pipelines I would then checkout the tag detached. Are there any more consequences in using one or the other?

    Hope you're doing well. We are currently working on improving how we visualize our contract test results. Specifically, we would like to build a dashboard that can display these results, broken down by the different teams involved. We are exploring options for tools or platforms that could help us achieve this. Do you have any recommendations or experience with tools that are well-suited for creating dashboards of contract test results, particularly those that can show results per team? Any suggestions or insights you could provide would be greatly appreciated. Thank you for your time and assistance.

    Hi everyone 👋 Our team is considering using Pact for contract testing of message flows over Kafka and Apache Pulsar, while also leveraging the Schema Registry in both systems for schema validation ( with 
    BACKWARD
    compatibility type). Could you help clarify the main business cases for using both Pact and Schema Registry together? Specifically: • If we are already using the Schema Registry to enforce message structure and compatibility, does Pact contract testing become redundant? • Or does Pact provide additional value beyond schema validation? • If we decided to write contract tests for a Apache Pulsar messaging system, does Pact have any sort of integration - is it ready for that? (I wasn't able to find the necessary materials on this topic - everything is kafka centered 😅). Thank you very much for your insights!
