rspec - How to test ActiveRecord::RecordNotFound?

Question

I have a method to update people\'s attribute, and it will rescue ActiveRecord::RecordNotFound if the people cannot be found. The method is:

  def u         


        

Answer 1

you can try :

let!(:error_failed) { { error: 'Failed' } }

context 'when people is not found by params' do
  it 'return 404 and render json failed'
    null_object = double.as_null_object
    allow(People).to receive(:find).with(params[:id]).and_raise(ActiveRecord::RecordNotFound.new(null_object)

    put :update, format: :json, .....
    expect(response.body).to error_dailed.to_json
    expect(response.status).to .....
  end
end
