Stubbing Chained Methods with Rspec

Question

I want to call a named_scope that will only return one record, but the named_scope returns an array, that\'s not a big deal as I can just chain it with .first:

M         


        

Answer 1

The question is quite old and hence there are few enhancements in how stubbing can be done. Now you can use stub_chain method to stub a chain of method calls. For example:

@client = Client.named_scope(param).first

can be stubbed with:

Client.stub_chain(:named_scope,:first).and_return(@client = mock(Client))

More examples of stub_chaining:

describe "stubbing a chain of methods" do
  subject { Object.new }

  context "given symbols representing methods" do
    it "returns the correct value" do
      subject.stub_chain(:one, :two, :three).and_return(:four)
      subject.one.two.three.should eq(:four)
    end
  end

  context "given a string of methods separated by dots" do
    it "returns the correct value" do
      subject.stub_chain("one.two.three").and_return(:four)
      subject.one.two.three.should eq(:four)
    end
  end
end

Long live the rspecs!!! :)
