在rspec测试中加载模块

Question

I have the following test...

spec/features/users/sign_in_spec.rb

require "rails_helper"
feature "User sign in" do
    extend SubdomainHelpers
    let!(:account) { FactoryGirl.create(:account) }
    let(:sign_in_url) { "http://#{account.subdomain}.example.com/sign_in" }
    let(:root_url) { "http://#{account.subdomain}.example.com/" }
    within_account_subdomain do
        scenario "signs in as an account owner successfully" do
            visit root_url
            expect(page.current_url).to eq(sign_in_url)
            fill_in "Email", :with => account.owner.email
            fill_in "Password", :with => "password"
            click_button "Sign in"
            expect(page).to have_content("You are now signed in.")
            expect(page.current_url).to eq(root_url)
        end
    end
end

Note the 3rd line extend SubdomainHelpers which I am trying to load from...

spec/support/subdomain_helpers.rb

module SubdomainHelpers
    def within_account_subdomain
        let(:subdomain_url) { "http://#{account.subdomain}.example.com" }
        before { Capybara.default_host = subdomain_url }
        after { Capybara.default_host = "http://www.example.com" }
        yield
    end
end

When I run the text I get the error uninitialized constant SubdomainHelpers (NameError) How do I call the SubdomainHelpers module from the test?

Answer 1

You need to require 'support/subdomain_helpers' in your rails_helper or the sign_in_spec file.

Files in the spec/support subdirectory are automagically loaded into LOAD_PATH by rspec, but they're not required.
