Testing methods that make http requests

Question

I have some methods in my app that make http requests. Is there a good way to simulate network failures and bad responses for the unit tests?

Answer 1

Suitable Mock Objects should let you perform such simulations easily; if you're unfamiliar with the concept, there's a good tutorial here.

Answer 2

For network failures nothing beats first unplugging your computers ethernet cable (or d/c it's wireless) and then unplugging whatever cable gives you access to the cloud.

If by bad responses you mean HTTP errors you can write ASP scripts that will always throw specific errors. If you want to test malformed HTTP packets you'll have to write a simple socket app to do that.
