rspec test that a request makes certain changes to a model. How can I do something like this?
describe "my request" do
it "should update the model" do
Model.any_instance.should_receive(:save) do
self.changes.should include(:attribute)
self.attribute.should == 'value'
end
xhr :put, model_path(model), {attribute: 'value'}
end
