Stub calls to third party services using WireMock - integration-testing

I tried to find a way to stub calls to external services via WireMock. WireMock easily mocks any relative URL, but what if we want to intercept a REST call, which was sent from our node to some 3rd party service and return predefined response? Is there any possibility to do that?

I did a workaround by extracting the host as application configuration.
So if your application sends requests to:
http://thired-party-service.com/someEndPoint
You can extract the host as configuration param:
host=http://thired-party-service.com/
Now when you running in a test context fill the host param with same host as your WireMock server, for example:
host=http://localhost:8080/
Now you can use WireMock stubs as usual.

Yes, check out the proxying section in the docs: http://wiremock.org/docs/proxying

Building URLs in Go including server scheme

I am creating a REST API in Go, and I want to build URLs to other resources in my replies.
Based on the http.Response I can get the Host and URL.
However, how would I go about getting the transport scheme used by the server? http or https?
I attemped to check if server.TLSConfig is nil and then assuming it is using http since it says this in the documentation for http.Server:
TLSConfig *tls.Config // optional TLS config, used by ListenAndServeTLS
But it turns out this exists even when I do not run the server with ListenAndServeTLS.
Or is this way of building my URLs the wrong way of doing things? Is there some other normal way of doing this?
My preferred solution when running http and https is just to run a simple listener on :80 that redirects all traffic to https. Then any real traffic can be assumed to be https.
Alternately I believe you can access a request's URL at req.URL.Scheme to see the protocol.
Or do you mean for the entire application? If you accept configuration to switch between http and https, then can't you look at that and see which they chose? I guess I'm missing some context maybe.
It is also common practice for apps to take a baseURL via flag or config to generate external urls with.

When service through external host name returns wsdl html instead of the expected response envelope

I have an IIS-hosted, WCF web service deployed on a UAT web server. In IIS, I have site bindings on this same web service--one for internal access (Ex: uat-nodotsinternalonly) and one for external access (Ex: mysvc.uat.mydomain.com).
When I use SoapUI to test against the internal host name (http://uat-nodotsinternalonly/MyService.svc), it calls the service and returns the response envelope as expected.
When I use SoapUI to test against the external host name (https://mysvc.uat.mydomain.com/MyService.svc), it calls the service and returns the WSDL HTML as would be seen in the web browser instead of the response envelope as expected.
We need to expose past our firewall for testing with a vendor. Our external client can browse to our web service using the external host name and receive the WSDL back in their web browser, but when they call it, it fails with a 302 error.
I’m far from an expert on security, but I believe our firewall is handling the security then forwarding over http to the UAT server. The redirect and variations seem as though there’s something to change in how DNS is managed or settings in IIS. Does anyone have suggestions as to how to narrow it down so that the call to the external service will work?
We too had a WCF service that in SoapUI was returning the WSDL HTML instead of the expected response when invoking a method. This was an SSL-enabled service, and the solution in our case was to edit the endpoint URL after creating the request so that it used https instead of http. This is because we found that for some reason it defaults to http even when you initially specify https when creating the request. Here's how to edit the endpoint URL in SoapUI:
In the request window, click the drop-down arrow on the URL.
Select [edit current..]
Change http to https, and then try your request again.
The problem with the client getting a 302 error was because the client was not sending a SOAP request envelope to our web service. The client was just sending XML.

Testing the request generated for the backend service

I have an apigee proxy that routes request to backend services - which is a standard usecase. In the dev environment the backend is lenient in terms of headers/query params. However this is not the same in the production environment - the backend server operates in strict mode.
I would like to validate the request sent to the backend - probably using JMeter in dev mode so that the proxy does not fail in production. Any ideas on how to do this?
One of the ways is to copy the request sent to backend on to the response and validate final response in JMeter. This may not work in all cases.
I would like to know vairous ideas that people have tried to test in such a scenario.
Please assume that the dev backend cannot be made strict due to variety of circumstances.
One possibility is to add an HTTP header indicating that you are in testing mode. Then use RouteRules in the ProxyEndpoint to send the request to a testing endpoint instead of your normal backend if that header was supplied. That testing endpoint could receive and validate your request. You could also do this with an optional service callout before the normal call to the backend.

Intercepting the SOAP envelop in an HttpRequest

I want to look at the XML created in my HttpRequest but can't see how. I've tried looking at the request during runtime but no luck.
I'm working in a .NET 4.0 project (just for context here, not that it matters much starting with 2.0)
I'm making a call to a third party API via my project's service reference:
SomeResponseType response = _apiClient.AddUser(userToAdd);
So how do I capture what AddUser is creating in terms of the raw XML being sent to the host without having to go through the pain of creating an Intercept filter which is not the easiest thing to put together?
You should be able to use Fiddler on your machine to capture the underlying HTTP request.
Alternatively, if you're using WCF, you can enable tracing via your config file. To go this route, see Configuring Message Logging. Then you can use the Service Trace Viewer Tool (SvcTraceViewer.exe) to pretty print your logs.
You can use a network sniffing tool such as Fiddler (www.fiddler2.com). Simply fire up Fiddler and then run your app. Fiddler will capture all of the traffic that is going across the wire, and you can look at the XML that is being sent and received from the SOAP service.
