Problems mocking go-sdk on v1.12 with unexported structs

[Jossec101]

Hello, we do mock some dapr client internally and since v1.12 the conversation structs are unexported and making us harder to mock the dapr client.

Im talking about this specifically:

We are facing this issue as well. We mock the dapr client for unit tests and are unable to upgrade to the latest for this reason.

My temporary workaround for this was to pass an interface only with the methods i used from the dapr client. Then i only had to mock these

type Client interface {
	PublishEvent(ctx context.Context, pubsubName, topicName string, data interface{}, opts ...dapr.PublishEventOption) error
	InvokeMethodWithContent(ctx context.Context, appID, methodName, verb string, content *dapr.DataContent) (out []byte, err error)
}
