I'm not aware of any official examples with that combo. What does the introduction of test containers change?

Automation and an isolated testing environment

I understand what they are, sorry, but I'm wondering what additional information you'd need in our examples to make it work that you couldn't extrapolate on your own? Or put another way, we can't create examples with all combinations of frameworks and tools so we try and highlight the relevant points for users to integrate as needed into their tools. If we could improve that of course we would like to help

Well, I've not pretended any of the above. I just simply asked if there is an example? There is not.... That's it. Obviously the question was not restricted to pact Devs but also to everyone that works with it and may have implemented it in this way. I feel like every time I ask about pact features there is a kind of self defense answer.

#534 RFC: Throw explicit timeout errors on verification Issue created by isaac-r ## Issue When running the verifier if the verify method times out there is nothing in the logs to explain the issue is timeout rather than a failing pact verification. ## Solution Add explicit timeout messaging in the

Execute

method of

pact-net\src\PactNet\Verifier\InteropVerifierProvider.cs

by passing down the

timeout

Timespan from

pact-net\src\PactNet\Verifier\PactVerifierSource.cs

. Wrapping the result in a try-catch, the explicit timeout exception can be caught and thrown back up. ## Further work I have encountered further issues with no explanations in the errors dure to the limited feedback from the pact-core errors. It would be useful to log config/set up errors with the pact server and return status codes when running the mock server if requests fail or if the application stop unexpectedly. ## Alternatives This could be done in pact-core and updated with additional errors for connection issues to the mock server pact-foundation/pact-net

Hi, I'm trying to run my app using minimal api in .NET 9 but I'm running into an issue when using a process to run the app. I am following on advice given in this answer: https://stackoverflow.com/a/77231959/18482058 but I am unable to get my application to keep running within the process (see the discussion under the answer)

Hi all, We’re looking to implement message-based contract tests for Azure Service Bus messages. The consumer expects certain headers to be included with the messages. Is there a way to specify headers when to be included in the pact? I’ve come across the .WithMetadata method, but I’m not sure if that’s the appropriate approach for setting headers. Thanks!

#535 Test Host Process Crashes After 5.0.1 Upgrade Issue created by adamrodger Version information: • OS: Linux x64 • PactNet Version: 5.0.1 • .Net Version: 9.0 Describe the bug After the upgrade from PactNet 5.0.0 to 5.0.1, I get an error when running provider tests inside a .Net Docker container:

The active test run was aborted. Reason: Test host process crashed

Test Run Aborted.
       _VSTestConsole:
         MSB4181: The "VSTestTask" task returned false but did not log an error.
     1>Done Building Project "/app/tests/MyProject.Pacts/MyProject.Pacts.csproj" (VSTest target(s)) -- FAILED.

Build FAILED.

    0 Error(s)

Time Elapsed 00:00:03.52
Process exited with code 1
Test ignored: MyProject.ProviderTests.VerifyPacts, ignore reason: Interrupted by build execution timeout

Consumer tests work absolutely fine, it's only provider tests that crash. Steps To Reproduce Unsure currently - it was working fine before the upgrade Additional context The diff between 5.0.0 and 5.0.1 only really has an FFI upgrade in it, so I'm assuming the issue is there and that it's crashing the provider tests. pact-foundation/pact-net

Hi! We are working on the implementation of PACT in some API projects. We have the following case: One of the endpoints returns an array, and the problem we encountered during provider validation was that the order defined in the contract was different from the one returned by the API. For now, we have resolved it by sorting the array in the contract to match what the provider returns. However, our question is if there is any other way to do this and what best practices we can apply in this case. Thanks!

#538 Messaging pacts - guidelines to provide real message to verifier Issue created by scrocquesel-ml150 I'm working on implementing the messaging verifier. In my case, the provider sends messages to an Azure Service Bus in response to certain interactions. I want to verify that these messages conform to the consumer pact. Looking at the examples, it seems that messages are manually constructed in the tests. #459 call them canned message. IMHO, this introduces a risk of divergence between the actual messages sent by the application and the ones defined in the test. What I’ve done instead is configure the provider to send messages to a Service Bus Testcontainer during integration tests. A MessageProcessor dequeues the messages and transforms them into Pact scenarios. Once all integration tests have passed, I use the collected scenarios with the message pact verifier. What do you think of this approach? pact-foundation/pact-net

#539 Request/Response and messaging in same service; how do we filter? Issue created by robbiewareham I am using PactNet 5.0.1 and I have a service that provides the following: • POST request is made to my service which results in a message being written to a 3rd party queue. I now have two pact files hosted in PactBroker; one generated by the consumer of the POST endpoint, the other generated by the process that reads the messages from the queue. I've implemented the verification by having 2 classes, each with one Xunit test. One class uses

MessagingProvider

and is configured to download from a pact broker:

using var verifier = new PactVerifier(config);
   
 verifier.MessagingProvider("personal-details-api", CreateJsonSettings())
         .WithProviderMessages(scenarios =>
         {
             scenarios.Add("An event is created", _event);
         })
         .WithPactBrokerSource(_pactBrokerUri)
         .Verify();
 }

I was hoping/assuming that this would only download the messaging pact from pact broker but it is also downloading the request/response pact too so fails as it only expects messages. The "provider" name in Pact Broker is the same (which makes sense to me as the provider is the same), but do I have to have unique provider names? pact-foundation/pact-net

#540 How to authenticate to the Provider target endpoint ? Issue created by rpbs Version information: • PactNet Version: 5.0.1 • .Net Version: 8 Describe the bug Not a bug but I'm not being able to pass Authorization with a Bearer to the header of the Pact Uri Steps To Reproduce I have a pact verifier, I need to be able to authenticate to the Provider Uri.

httpVerifier.WithHttpEndpoint(providerUri)

Then I'm calling

Verify()

method Log Output I'm getting 401 Could you guys help me to understand what I'm missing ? pact-foundation/pact-net

#541 feat(verifier): Added support of set_no_pacts_is_error feature Pull request opened by levanoz Added support for the set_no_pacts_is_error feature, implemented similarly to how it's done in pact-js and other Pact libraries. pact-foundation/pact-net

Hi, We have a provider test of an AMQP interaction in Pact. The interaction has a "description" and "providerStates". We added in the test:

.WithMessages(scenarios =>  {
                    scenarios.Add(
                        "scenario description",
                        builder => SetupDescriptionA(builder));
                }, _serializerOptions) ...

and the state handler "prepare data" in the middleware. I would expect the state handler to execute FIRST to prepare the data for the content of the message, and THEN the description handler to execute SECOND so that it uses a messageProducer function to generate the message based on the prepared data, But it is the opposite! This forces us to abandon providerStates and only use descriptions for both setting the environment and producing the message. In case, I misunderstand something please let me know. Thank you in advance!

#542 Sequence of "description" and "providerStates" in messaging provider verification. Issue created by dranidis Version information: • OS: Arch Linux • PactNet Version: 5.0.1 • .Net Version: 8.0.100 • Pact Broker Version (if applicable): NA Describe the bug Description handler is executed before the state handler. Steps To Reproduce The current behaviour can be reproduced with the code in this repo:

<https://github.com/dranidis/pact-dotnet-message-provider>

Expected behavior We have a provider test of an AMQP interaction in Pact. The interaction has a "description" and "providerStates". We added in the test:

.WithMessages(scenarios =>  {
                    scenarios.Add(
                        "scenario description",

#543 RFC: Configure a custom port for the mock server Issue created by scrocquesel-ml150 Is your feature request related to a problem? Please describe. I'm running Pact on the host and the client is in a testcontainer. Having a container call the host is a bit difficult and testcontainer has some helpers but it requires to know the server port in advance. Describe the solution you'd like I want to configure the pact listening port in the Options instead of relying on the FindUnusedPort. Breaking Changes No, if the port is not configured, it use the FindUnusedPort. Potential Downsides/Caveats The user is responsible to pass port that is not currently used. Describe alternatives you've considered Start pact first but not very convenient in how the test fixture are writtent Additional context The Js version has such a config https://github.com/pact-foundation/pact-js/blob/8c8348b5188b8819f90b10d26834c222e4e7b744/src/v4/http/types.ts#L34-L37 pact-foundation/pact-net

#514 Improve target frameworks and their package references: Pull request opened by SymbioticKilla Hi @adamrodger, sorry for PR before creating an issue to discuss. I think it is easier to discuss it within PR, if you are interested in this change. 1.) Add net8.0 as a target framework to support latest LTS version and to use latest compile improvements with less package references 2.) Add conditions for package references => net8.0 doesn't need them 3.) Remove net462 => netstandard2.0 is already a compatibility mode framework to support all .NET versions. There is no need to specify old .NET frameworks. 4.) All projects except nuget projects can reference only net8.0. There is no need for multiple target frameworks pact-foundation/pact-net

Hey everyone, is there a way to specify the URL to use for pact messages? It seems to grab the base URL from the "WithHttpEndpoint" method and slaps on a port + "/pact-messages". The issue is that the URL we pass in when running this in a pipeline is an APIM URL, so it gets a 404. We need it to use localhost when calling for the pact messages

#544 MessageProvider listening on localhost returns 404 Issue created by scrocquesel-ml150 Version information: • OS: WSL with Windows x64 • PactNet Version: 5.0.1 • .Net Version: 8.0 Describe the bug I'm trying to verify message interaction for a producer. The sample project in this repo works fine, but with my project, when pact tries to request

<http://localhost:41952/pact-messages/>

, it receive a 404 response without going through the

HandleRequest

method of

MessageProvider

. If I modify the prefix uri with

127.0.0.1

, then it works in all cases. What is important is that the Uri added to the HttpListener must be

127.0.0.1

. Then, the returned uri can be the

ip

or

localhost

it works in both cases. I know it is connecting to the listener somehow because if I comment out the start of the HttpListener, then it cannot connect. There is definetely something going in the middle with

localhost

but I can't figure it out. Steps To Reproduce I didn't succeed yet identifying what's going on. Expected behavior The listener should be able to receive pact_verifier request Log Output

hello people! First time doing contract testing, and would appreciate some help. Im creating a consumer test with: pactBuilder .ExpectsToReceive("response") .Given("Received x") On the producer side I can do: verifier .WithMessages(scenarios => { scenarios.Add("response", builder => { builder. WithContent(() => ""); }); But how do I consume the ".Given("Received x")"? I've tried reading the docs but I could not find anything related to this (Im using Messages not HttpRequests)

Hi, We wanted to write consumer tests for a swagger with oneof, anyOf key words. It seems that Pactflow supports these keywords using

discriminator

, but the Pact.NET library doesn't seems to support this. Could you please let us know, how we should proceed further to test this? Thank you. https://docs.pactflow.io/docs/bi-directional-contract-testing/contracts/oas/keyword-support#general-advice
