rspec 3 - stub a class method

Question

I am upgrading from rspec 2.99 to rspec 3.0.3 and have converted instance methods to use allow_any_instance_of, but haven't figured out how to stub a class method. I have code like this:

module MyMod   class Utils     def self.find_x(myarg)       # Stuff     end   end end 

and my rspec 2 test does this:

MyMod::Utils.stub(:find_x).and_return({something: 'testing'}) 

What is the Rspec 3 way of doing this?

Answer 1

You should do

allow(MyMod::Utils).to receive(:find_x).and_return({something: 'testing'})
