Rspec: how can I check if a call to a method of another class is called?

Question

I can I check if FeedItem::populate_from_friend_to_user is called inside the user class?

    it "should auto populate feed after user.add_friend" do
      @user.add_friend(@friend1)
      @user.should_receive('FeedItem::populate_from_friend_to_user').with(@friend1, @user)
    end

With the above code I get:

undefined method `populate_from_friend_to_user' for :FeedItem:Symbol

You should not know where the method is called, just if the method is called.. You just know if the method is call:

Before RSpec 3

 it "should auto populate feed after user.add_friend" do
    FeedItem.should_receive(:populate_from_friend_to_user).with(@friend1, @user)
    @user.add_friend(@friend1)
 end

In RSpec 3 the syntax is

expect(Object).to receive(:method).with(params)

This is `Object.should receive(:method).with(params)` now – Chris Nicola Mar 21 '12 at 00:04

@ChrisNicola: my experience doesn't bear this out? – Asherah Sep 06 '12 at 01:04

Remember that is works only in rspec2 . For rspec3 u call

expect(@user).to receive(:your_method)

what if `:your_method` is a class method? – j will Aug 17 '15 at 17:55
Then you don't expect to run it on object i suppose? I am not sure if i got your question ;] – Adam Piotrowski Aug 19 '15 at 14:02

If you want to test if a class method is called, do this. `expect(User).to receive(:your_method)` – Arun Kumar Mohan Jul 14 '16 at 02:38
You can also specify how many times you expect class to receive method, e.g.: `expect(User).to receive(:your_method).thrice` – dinjas Jul 11 '17 at 19:20
