"undefined method `stub_request'" when accessing the method in an RSpec support file

I have the following file struture in my Ruby-on-Rails project, for the specs:

/spec
  /msd
    /service
      service_spec.rb
  /support
    /my_module
      requests_stubs.rb

My request_stubs.rb have:

module MyModule::RequestsStubs

  module_function

  def list_clients
    url = "dummysite.com/clients"
    stub_request(:get, url).to_return(status: 200, body: "clients body")
  end
end

In my service_spec.rb I have:

require 'rails_helper'
require 'support/my_module/requests_stubs'
...

because I only want the method available in this file.

The problem is that when running the tests I call the method MyModule::RequestsStubs.list_clients in the service_spec.rb file, I get the following error:

Failure/Error:
       stub_request(:get, url).to_return(status: 200, body: "clients body")

     NoMethodError:
       undefined method `stub_request' for MyModule::RequestsStubs:Module

when accessing the WebMock method stub_request.

The WebMock gem is installed and is required in the spec_helper.rb file.

Why does the error occurs? It looks like it can't access the WebMock gem, or don't know how to access it. Any ideas on how to solve it?

stub_request is defined in the WebMock namespace, so you have to use WebMock.stub_request. To make it available globally, you need to add include WebMock::API to your rails_helper.

Even better, include webmock/rspec instead of just webmock -- it will take care of including the WebMock::API as well as setting up the webmock RSpec matchers.
