Hi guys, I have errors when I perform tests on the content type. And I don’t understand why! I have this message:

Copy code

2.1) includes header 'Content-Type' with value 'application/json; charset=utf-8'
           Expected header 'Content-Type' to have value 'application/json; charset=utf-8' but was 'application/json; charset=utf-8'

But for me the 2 strings are equal. How can I fix this?

I have this near the end of a test I’m trying to write:

Copy code

err = mockProvider.ExecuteTest(t, doTestCreateGithubRepo)

With this as definition:

Copy code

var doTestCreateGithubRepo = func() func(config MockServerConfig) error {
	return executeTestCreateGithubRepo("foo")
}()

var executeTestCreateGithubRepo = func(repo string) func(config MockServerConfig) error {
   ...
}

I would like to have access to

t *testing.T

within

executeTestCreateGithubRepo

for the test logging functions. How can I do that?

I don’t think you need the

doTestCreateGithubRepo

function at all. I think you can just do something like this:

Copy code

err = mockProvider.ExecuteTest(t, executeTestCreateGithubRepo("foo", t))

and then

Copy code

var executeTestCreateGithubRepo = func(repo string, t *testing.T) func(config MockServerConfig) error {
   ...
}

How should I write that one property in a

Map

is another composite object (not array)?

Copy code

WithJSONBody(Map{
   "id":        Integer(1296269),
   "node_id":   S("MDEwOlJlcG9zaXRvcnkxMjk2MjY5"),
   "name":      S("foo"),
   "full_name": S("theorg/foo"),
   "owner": Map{
	   "login": S("theorg"),
   },
})

The above gives me an error on the line where I specify another

Map

for

owner

Hello pact-go team, this may have been answered somewhere already and my channel and repo search terms may be off-point, but is there a timeline for the v.2.xx.xx release out of beta? I am doing some proof of concept work for my company, work which is moving rapidly. Stability is obviously a priority as we get more serious with it, so v1.xx.xx seems correct for now, but just getting a sense of a timeline for a stable release of v2.xx.xx, at your convenience. Cheers!

Hi all, In

Pact-jvm

you have the option to define different matching rules for an attribute using the OR condition. I have recently gone through the rust codebase of the

libpact_ffi

library which is used by pact-go and I didn't see any support for

OR

matching rules, at least for Pact V3 and V4. Is there any plan to introduce this feature? This is kind of useful as i have to deal with some cases when an attribute may be null, but if it isn't it must obey a certain regex.

hi pact-go team, apologies for the long question. thanks in advance for your help! 🙏 i've upgraded my

pact-go

v2.0.0-beta.14

and updated my consumer test to use Pact V4 such as replacing

NewV3Pact()

with

NewV4Pact()

. i understand that Pact V4 adds a `key` field to an interaction and its value seems to be some hash when i looked at its value in the pact generated when i ran my test. i'm guessing the hash is calculated using the

description

provider_states

request

response

and

pending

fields in https://github.com/pact-foundation/pact-reference/blob/9d30a4411dfab9f0993070ef34d2ea8bf8d28a6d/rust/pact_models/src/v4/synch_http.rs#L397 i ran my consumer test several times without changing the interactions. when i inspected the value of the

key

field in the pact file generated, i was surprised to see that its value changes between runs. should its value stay the same instead since the pact didn't change? the pact broker thinks my consumer published a new pact, but it shouldn't be the case since i just generated again the same pact and published it without changing anything. i've attached a snippet of my simplified setup of the mock provider with interactions in this thread for reference.

Hey 👋 We are trying to use pact for creating contracts for kinesis events, the consumer listens for proto’s that are sent through. We are creating matchers using similar code as below:

Copy code

WithContent(map[string]interface{}{
			"moneyToMove":           term(),
}).WithType(&myproto.MyProtoName)

The issue we are running into is that the unmarshaller is not able to unmarshal to proto types. Is there some methods that can be overriden to achieve this? The error that we end up getting is:

Copy code

VerifyMessageConsumer failed: unable to narrow type to : json: cannot unmarshal string into Go struct field myproto.created_at of type timestamppb.Timestamp

Hey does anyone know how to set the port for the mock server during the pact setup in golang?

Question about 2.x.x. I'm trying out the latest beta and was wondering how to configure the

PactLogDir

for a provider verification. In the latest 1.7, the field is on

VerifyRequest

Is this still configurable?

Hey I'm using pact v2.x.x to write a contract test between two of my grpc services. Andfor consumer get such error:

is it because the .proto file is not reachable when I do

Copy code

cat /home/robert/go/src/giltab.elona.com/elona/dev/rosi/module/card/pact_tests/consumer_tests/../../../secure/pb/service_modulesecure.proto

it prints the protofile.

binary.

07/28/2022, 10:58 PM

There should also be logginsg at the plugin level that may indicate what is going on.

Matt (pactflow.io / pact-js / pact-go)

07/28/2022, 10:59 PM

In your ~/.pact/plugins directory there should be the installed protobuf plugin. Please double check the permissions there and ensure the binary can run.

Matt (pactflow.io / pact-js / pact-go)

07/28/2022, 10:59 PM

The framework attempts to automatically install protoc if it doesn’t exist, this may have failed also

Robert Henzel

07/29/2022, 6:37 AM

Funny thing happend. When I regenerated the proto file with name

servicemodulesecure.proto

instead of

service_modulesecure.proto

I could reach it and the

protoc

binary was invoked. At first I thought that it cannot parse

from path but after I changed it back to

service_modulesecure.proto

it alswo worked. 😕 Edit: I think the permissions are all right because I was able to run the tests from

pact-go/examples/grpc

directory without problems.

What if a providers grpc handler calls another grpc method (provider is a consumer here e.g crypt service). How can I test provider in that case. Right now I have it mocked but it does not work.
