当我使用 gem 'selenium-webdriver' 运行测试时（带有“ describe "with valid information", :js => true do”）

规范/请求/post_pages_spec.rb

require 'spec_helper'

describe "Post pages" do
  subject { page }  
  category = Category.create(name: "Food")
  let(:post) { FactoryGirl.create(:post) }
     describe "with valid information", :js => true do
      it "should create a post" do
        fill_in "Title", with: post.title
        fill_in "Content", with: post.content
        fill_in "Publish", with: Date.today
        check "Food"  
        expect { click_button "Create Post" }.to change(Post, :count).by(1)
      end
    end
  end

我在规范中遇到错误：

Failures:

  1) Post pages post creation with valid information should create a post
     Failure/Error: expect { click_button "Create Post" }.to change(Post, :count).by(1)
       count should have been changed by 1, but was changed by 0
     # ./spec/requests/post_pages_spec.rb:35:in `block (4 levels) in <top (required)>'

但是当我在没有 Selenium ( describe "with valid information" do)的情况下运行测试时，
测试是绿色的。

为什么 Selenium 不创建 Post 并使测试变为红色？
如何解决？

解决方案是 Capibara 与 Rspec 的特定工作。
我将以下文件添加到spec/support/database_cleaner.rb

RSpec.configure do |config|
  config.use_transactional_fixtures = false

  config.before :each do
    if Capybara.current_driver == :rack_test
      DatabaseCleaner.strategy = :transaction
    else
      DatabaseCleaner.strategy = :truncation
    end
    DatabaseCleaner.start
  end

  config.after do
    DatabaseCleaner.clean
  end
end

在中添加了宝石Gemfile:

group :development, :test do
  gem 'database_cleaner'
end

$> 捆绑安装

我在下面的行中添加了评论spec/spec_helper.rb

RSpec.configure do |config|
  #config.use_transactional_fixtures = true
end

测试变为绿色。
