在rspec测试中加载模块

Question

我有以下测试...

规格/特征/用户/ 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

请注意我尝试加载的第3行extend SubdomainHelpers ...

规格/支持/ 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

当我运行文本时，我收到错误uninitialized constant SubdomainHelpers (NameError)如何从测试中调用SubdomainHelpers模块？

Answer 1

您需要在rails_helper或sign_in_spec文件中require 'support/subdomain_helpers'。

spec/support子目录中的文件由rspec自动加载到LOAD_PATH，但不是必需的。
