@Jeremy,

In this case, yes, I’m testing the saga end-to-end so I’m creating “proxy” handlers that produce the appropriate response from the stimulus (in this case, the Publish in the saga) so that the saga can achieve completion in this “happy path” test.

I’ll schedule a post on testing sagas as part of this series, thanks for bringing it up.

sorry i wasn’t all that clear… wouldn’t think of calling the web service direct in a test. i was curious if you might be using an automocker or generic test helper class so as to not have to write a proxy for each Publish call in the saga. In the saga_spec the OrderDetailsWebServiceProxy is faked in the GatewayService project. is that faked proxy class normally what you would create in the test project to stub?
btw thanks for this series of posts they’ve been helpful. i’m going back to an app using MT and trying to get some tests around the saga’s after inspiration from this post.

@Jeremy:

Do we create proxies for the actual call to the web service? Yes. We never talk to the external web service directly, it’s always done through a proxy/gateway class.

Thanks Chris…. been struggling with writing unit tests for saga’s. Really wish the samples in masstransit had tests around them… One question do you create proxies like this in when testing production code or is there a better way?

I’m curious how asp.net mvc integration into this sample will go

Thanks for the tutorial – more of this is needed imo (it really helps)

Hi Chris, is there a bug in the Proxy_Specs line 45

You have
var request = new SendOrderDetailsRequest();

But I think it should be:

var request = new SendOrderDetailsRequest { OrderId = orderId, CustomerId = customerId };

Then I get passing tests
