I have Integration Tests failing when run at once, but pass if run separately.
The tests are for Service 1 which initializes dependent Service 2. Service 2 receives HttpClientHandler through DI where it sets default behavior (AllowAutoRedirect property).
Due to a test scenario I have to use HttpClientHandler to create the HttpClient in Service 2. (To be specific the call through HttpClientHandler is intercepted in the Integration tests where response content is changed. There is no way to do this through HttpWebRequest and HttpClientFactory. Hence the default behaviour for HttpClientHandler is in Service 2's constructor).
Why am I getting this error when tests are run at once? What is happening twice? The tests work fine separately which is honestly baffling.
System.InvalidOperationException : This instance has already started one or more requests. Properties can only be modified before sending the first request.
Stack Trace:
SocketsHttpHandler.CheckDisposedOrStarted()
HttpClientHandler.set_AllowAutoRedirect(Boolean value)
Have I made a design sin somewhere?

I am exploring Karate API double (mocking) for the integration test. For the below scenarios, I'm not getting the expected mocking response. Your help will be appreciated.
My Setup :
1. Karate Mock Server up with pathMatches rules on port 8001: http://localhost:8001 ( working, validated against "/cat" and some test calls)
2. My own Application is up from docker on port 8080. From Docker exposed 8001 port as well.
Mocking Case:
1. My application REST call exposed to all users http://localhost:8080/service/v1/findUser. This exposed API, underlying calling other REST call http://dev-STG/userservice/v1/findUser which actually giving JSON response. So, I want to mock underlying API call and validate my API behavior accordingly.
Steps tried:
1. Now, in my application config, m replacing actual underlying API call to Karate mock server(http://localhost:8001/userservice/v1/findUser). Then did build & up my application docker.
In Karate, I defined test e.g "testIntgrtn.feature" which calling my application API "http://localhost:8080/service/v1/findUser" and Karate mock server up and set with pathmatch "/userservice/v1/findUser".
After executing "testIntgrtn.feature" karate not mocking for an underlying call(http://localhost:8001/userservice/v1/findUser).
Now, in "testIntgrtn.feature" file I changed my-application URL to underlying REST URL i.e (http://localhost:8001/userservice/v1/findUser) then mocking will work like charm.
I'm not understanding why underlying API call not getting mocked here? Did I miss something here?
Also, in Karate can we monitor all REST calls (like cypress mocking).
Thanks for this wonderful framework. Which is intuitive for writing automation cases.
Karate cannot automatically intercept calls.
The recommended approach is when you boot the application running at localhost:8080 you change the configuration so that instead of calling http://dev-stg/userservice/v1/findUser it calls something like http://localhost:8001/v1/findUser. This is what most teams do, and is easy because you should anyway be defining external URL-s as application.properties (or equivalent) as a best-practice.
It is very easy to over-ride an application property in Spring Boot for example, you can do this via the command-line: https://stackoverflow.com/a/37053004/143475
If you want, you can dynamically provision a port for the mock. So your unit test can first start a mock, get the port, and then start the server. You can find details in the Karate documentation.
All this said, if you are able to change the (system) HTTP proxy before the app at localhost:8080 starts, you may be able to do this without modifying the configuration. (But it is tricky, so I recommend the approach explained above.) So in this case, Karate can actually "intercept" the outgoing HTTP calls that the app at localhost:8080 makes.

so I've created several service tests where I validate the response object, normally using the requests library or http library to send a POST request for example.
This time however I'm doing an end-to-end test. Through the UI progressing through a workflow, one stage involves uploading a document, behind the scenes this will call a separate service, the response of which will contain some information that could be useful to me for further verification.
Is there a way to merge these? After the UI action can I 'listen' for the response object somehow?
I do NOT wish to call the endpoint directly as I want to prove the workflow is as intended, the endpoint is verified directly in service level tests already.
Integrate Selenium tests with BrowserMob Proxy and you will be able to 'listen' for the responses using HAR file:

i'm trying to set up some code that needs access the PerRequest lifestyle. this lifestyle can't be access from within the AppStart of the global.asax.
How can i effectively run initialization code on a wcf service outside of appstart?
this is so that i can configure what documents are versioned in my RavenDb - to do this i have to specify the perrequest ifestyle - doing this in app start throws an exception.
Code that use the PerRequest lifestyle runs by definition per request.
You could split your initialisation code in two parts
What is not dependant on the per request lifecycle runs in Application_start
What is dependant on per request lifecycle runs as the first code in each request
Typically the binding of your ioc containers should be in application_start
here's the setup for the project.
I have a WCF Service that is hosted on a net.tcp binding in buffered mode and ReliableSession enabled.
The binding is configured to use TransportWithMessageCredential security. The certificate is a self signed certificate that I am identifying using the Thumbprint.
The UserNameValidator is a custom validator which for testing, never fails (it wasn't failing before but I removed the uncertainty)
The service and client are on the same machine and they both have access to the certificate.
The problem:
I am receiving a Socket Aborted exception when trying to consume a Method from the service. Here is the code I use to open a connection to the service. MonitorServiceCallbacks only contains empty methods to fulfil the requirements of the Interface.
_instanceContext = new InstanceContext(new MonitorServiceCallbacks());
_serviceInterface = new MonitorCallbackServiceClient(_instanceContext);
_serviceInterface.ClientCredentials.UserName.UserName = Environment.MachineName;
_serviceInterface.ClientCredentials.UserName.Password = "myPassword";
_serviceInterface.Open();
This appears to work fine as the _serviceInterface.State variable is set to State.Opened and the custom validator is called and returns without exception.
However, if I try to call a method using the _serviceInterface proxy, no code that I can break into is run on the service and the tracelog reveals no errors apart from a SocketAborted exception which occurs 1 minute after receiving what appears to be the message for the method.
There is no InnerException.
I have tried to google the issue but the results tend to say "just disable security and it will work fine". Unfortunately, this cannot be done.
I am extremely confused by this issue and any help would be greatly appreciated.
Many thanks,
Ehrys
This was actually a serialisation error.
The object I was trying to send to the service inherited from the data contract. So I was trying to send a cast down to the data contract to the service.
WCF doesn't appear to allow this.
I would like to thank John Saunders for reminding me that not only the service can have tracing enabled. Enabling client side tracing would have saved me a lot of time.
I was attempting to do the following:
_serviceInterface.Register((MyDataContract)MyParentObject, aVariable, anotherOne);
What I needed to do:
MyDataContract tempContract = MyParentObject.CreateMyDataContract();
_serviceInterface.Register(tempContract, aVariable, anotherOne);
/* Note: MyParentObject.CreateMyDataContract() is my own method which creates an instance
of the MyDataContract and copies the relevant information to it */
