Passing create inside of method rspec

Question

In controller you can pass create by the code below:

expect {
          post :create, params: {question: valid_attributes}, session: valid_session
        }.to change(Question, :count).by(1)

What if the create is inside of a method? I have a method that behaves find or create. And it will return the id.

def my_method(id='')
  if id.blank?
    question = Question.create(content: "The content.")
  else
    question = Question.find(id)
  end

  question.id
end

I do the Rspec like this:

it "should create for non existence of id" do
  expect(my_method).to have(1).record
end

it "should return object base on id" do
  expect(assigns(:question)).to eq(question)
end

But it gives me this error:

 NoMethodError:
       undefined method `have' for #<RSpec::ExampleGroups::ClassNameHere:0x00000008543a50>

Can someone help? Thanks!

Where is this my_method placed? and where do you call it from? — Jagdeep Singh

There is no magic. Instead of:

expect(my_method).to have(1).record

you should explicitly call the method (I assume it’s a class method of Question) and then check Question for having records. Methods do not have records for obvious reason:

Question.my_method
expect(Question).to have(1).record
