RhinoMocks Testing callback method
- by joblot
Hi All
I have a service proxy class that makes asyn call to service operation. I use a callback method to pass results back to my view model.
Doing functional testing of view model, I can mock service proxy to ensure methods are called on the proxy, but how can I ensure that callback method is called as well?
With RhinoMocks I can test that events are handled and event raise events on the mocked object, but how can I test callbacks?
ViewModel:
public class MyViewModel
{
public void GetDataAsync()
{
// Use DI framework to get the object
IMyServiceClient myServiceClient = IoC.Resolve<IMyServiceClient>();
myServiceClient.GetData(GetDataAsyncCallback);
}
private void GetDataAsyncCallback(Entity entity, ServiceError error)
{
// do something here...
}
}
ServiceProxy:
public class MyService : ClientBase, IMyServiceClient
{
// Constructor
public NertiAdminServiceClient(string endpointConfigurationName, string remoteAddress)
:
base(endpointConfigurationName, remoteAddress)
{
}
// IMyServiceClient member.
public void GetData(Action<Entity, ServiceError> callback)
{
Channel.BeginGetData(EndGetData, callback);
}
private void EndGetData(IAsyncResult result)
{
Action<Entity, ServiceError> callback =
result.AsyncState as Action<Entity, ServiceError>;
ServiceError error;
Entity results = Channel.EndGetData(out error, result);
if (callback != null)
callback(results, error);
}
}
Thanks
