Question

我有一个非常凌乱的Rails应用程序，我之前建立的，我目前正在扩展。这涉及Ruby版本（1.9.x到2.3.x），Rails版本（3.2.x到5.0.x）以及许多其他相关更改的一些重大更改。它有很多不妥之处，我不确定目前正在发生的很多事情。

为了理清我为自己创造的这个可怕的混乱，我决定用RSpec和Capybara写一堆功能测试。在我需要测试使用Javascript的东西之前，我取得了很好的进展（最终我的大多数功能测试都将测试Javascript）。

到目前为止，我的Rspec测试看起来像这样（还有很多东西需要完成 - 我刚刚被困在这里）;

feature "User registers a new customer", js: true do
    scenario "Logged in user registers a new customer" do
        user = FactoryGirl.create(:user)
        visit_root_and_login user  
        fill_in 'reg_number', with: '123456'
        click_button 'Look up'
    end
end

在我的应用程序中，这会触发一个AJAX调用，该调用会查找注册号并返回一段Javascript，它会根据客户之前是否已注册而向表单添加其他字段。

虽然这是怎么回事;

我尝试添加driver: :webkit以查看是否发生了任何不同的事情，并且略有不同;

我不明白为什么要调用“/javascripts/sessions.js”。我没有任何此类文件，我自己也没有提出此请求。它看起来来自Rack，但这是Ruby和Rails世界的一个区域，我真的不明白。

是否有人能够对此有所了解，所以我至少知道从哪里开始寻找？

TIA

好的，我把它排除了。

这是一个资产管道问题。

在我的application.html.haml我= javascript_include_tag "application", params[:controller]导致尝试在登录过程中将文件/app/assets/javascripts/sessions.js包含在我的资产中。我没有这样的文件所以创建一个空白的文件。然后我不得不添加

%w( sessions ).each do |controller|
  Rails.application.config.assets.precompile += ["#{controller}.js", "#{controller}.css"]
end

到我的/app/config/initializers/assets.rb，让它全部正常工作。

在我的服务器控制台的开发环境中引发了同样的异常，但我没有注意到它并且它没有停止执行。在Capybara，这个例外正在停止整个节目。

为什么我的rspec测试向javascripts / sessions.js发送get请求？
