I've been trying to stub open, the open-uri version, and I'm not succeeding.
I've tried doing the following but the request keeps going through:
Kernel.should_receive(:open).and_return("Whatever for now")
I've also tried to do
OpenURI::OpenRead.should_receive(:open).and_return("Whatever for now")
Since I tracked down that was where HTTP requests were made in OpenURI.
Thanks in advance for any suggestions!
Here is what I do
class Gateway
def do_something
open('http://example.com').read
end
end
In my spec i do the following:
describe 'communication' do
it 'should receive valid response from example.com' do
gateway = Gateway.new
gateway.stub_chain(:open, :read).and_return('Remote server response')
gateway.do_something.should == "Remote server response"
end
end
I'd recommend using something to stub the network instead. I believe the current favorite for doing so is FakeWeb [docs]. You may also be interested in fakeweb-matcher for rspec.
Alas, I think FakeWeb might not work with open(), actually, it stubs Net::HTTP, so I'm not sure if that will work. Any chance of not using open()? :)
