I\'m trying to do some testing with castle windsor involved, in one of my tests I want to check the windsor installers, so I check that the container can resolve my componen
In your test you could subscribe to the ComponentModelCreated event and change the lifestyle of your per-web-request components to something else. (example).
If you're writing an integration test with the scope of a single request, singleton should do.
If you're writing an integration test that spans multiple requests, you could use a contextual lifestyle to simulate the scope of requests.
Edit: including code from example (which is no longer available):
container.Kernel.ComponentModelCreated += Kernel_ComponentModelCreated;
…
void Kernel_ComponentModelCreated(Castle.Core.ComponentModel model)
{
if (model.LifestyleType == LifestyleType.Undefined)
model.LifestyleType = LifestyleType.Transient;
}
