Here you go:
It's not easy to test for the following named_scopes:
--
Thing.method1(@current_user).method2.method3 :page =>
params[:page]
--
I tried:
--
Thing.should_receive(:method1)..
Thing.should_receive(:method2)..
Thing.should_receive(:method3)
--
But testing for these three method calls didn't work. I have an error as
"could not evaluate nil.method2". That's because of the way Rails treats
chained named_scopes, each method only exists in the context of its
surrounding scopes. method1 doesn't anything when followed by method2,
it's because rails dynamically creates a method that would be called
something like method1_and_method2 if you know what I'm sayin'.
Therefore a workaround is to define an instance method:
--
class Thing
def self.method1_and_method2(arg)
method1(arg).method2
end
end
--
Then in the controller, you would call: Thing.method1_and_method2
Now you can spec that easily with:
--
Thing.should_receive(:method1_and_method2).with(...)
--
And it works.
