Mock out Curl::Easy.perform? (in Curb)

Question

Is there a way to mock out Curb's Easy.perform method for unit testing? I use this to hit Facebook's graph API, and none of the http mock libs seem to support Curb.

What's the best approach here?

Answer 1

WebMock has recently added Curb support. :)

Answer 2

I really think fakeWeb is a great way to fake out network calls; Whatever HTTP library you use, you'll just specify what response text and code you want to receive.

Described as:

FakeWeb is a helper for faking web requests in Ruby. It works at a global level, without modifying code or writing extensive stubs

Example from the github repository:

FakeWeb.register_uri(:get, "http://example.com/test1", :string => "Hello World!")

Net::HTTP.get(URI.parse("http://example.com/test1"))
=> "Hello World!"

Net::HTTP.get(URI.parse("http://example.com/test2"))
=> FakeWeb is bypassed and the response from a real request is returned
