Beginner Problems with WebMock and Rspec

[John]

This is my controller code

controller code :-

  def test

   image= Image.new(params)

   image.save

    image.rest_service

  end

Model

  def rest_service

   RestClient.post('i am here')

   end

it 'should return json with response code 200' do

     post '/orders/test', { order: {agreement_id: '101}}.to_json, get_headers(:private)

    expect(last_response.status).to eq(200)

  end

Problem

I have to stub rest_service request ,through webmock . but not sure where and how to add code

There are two options:

You can "spy" on requests or "mock" them. Or you can assert (expect) them to happen. In your case, it looks like you need just mock, which is pretty simple:

it 'should return json with response code 200' do

  stub_request(:post, 'i am here').to_return(:body => 'mocked response')
  post('/orders/test', { order: {agreement_id: '101}}.to_json, get_headers(:private))
  expect(last_response.status).to eq(200)
end
