I came up with a solution, for anyone that may stumble upon this in the
future.
Basically, I fire up a true instance of the web service when the
Integration Tests startup. Then I create a Channel and set CUT to that.
None of my tests had to change, just changed the base.
It's also nice, b/c NUnit is firing many concurrent requests at the service
at once, so it's inherently testing concurrency against a true instance of
the service.
private void Initialize()
{
if (_isInitialized)
return;
lock (SyncLock)
{
if (_isInitialized)
return;
// Register everything with IoC, PerWCFOperation
Application.Startup();
// localhost:8733 is a post left open for debugging
(http://stackoverflow.com/questions/885744/wcf-servicehost-access-rights)
var baseAddress = new
Uri("http://localhost:8733/Design_Time_Addresses/"; + typeof(T).Name);
var serviceHost = new
DefaultServiceHostFactory(IocContainer.Instance.Kernel).CreateServiceHost(typeof(T).AssemblyQualifiedName,
new Uri[] { baseAddress });
var serviceEndPoint =
serviceHost.AddServiceEndpoint(typeof(T).FullName, new BasicHttpBinding(),
baseAddress);
serviceHost.Open();
CUT = new
ChannelFactory<T>(serviceEndPoint).CreateChannel();
_isInitialized = true;
}
}
