Rails Rspec IntegrationTest Capybara

Question

我已经开始通过Rspec（水豚）测试我的应用程序。我是这么做的：

require 'rails_helper' 
RSpec.describe "Homepages", type: :request do 
    describe "GET/without login" , js: true do 
    before(:all) do 
     Employee.create(username: "username", password: "12345", password_confirmation: "12345") 
    end 
    it "works!" do 
     visit root_path 
     fill_in "loginname", with: "username" 
     fill_in "password", with: "12345" 
     click_button('sign_in') 
    end 
    end 
end 

由于env即“TEST-ENV”，我必须先创建一个员工。 的问题是，如果我运行“耙规范：要求”，我得到这个错误：

1) Homepages GET/without login works! 
Got 0 failures and 2 other errors: 

1.1) Failure/Error: 
     def initialize(template, original_exception) 
      super(original_exception.message) 
      @template, @original_exception = template, original_exception 
      @sub_templates = nil 
      set_backtrace(original_exception.backtrace) 
     end 

     ArgumentError: 
     wrong number of arguments (1 for 2)

Answer 1

我不知道，但我觉得更好，如果类型=拥有

样品

require "rails_helper" 

RSpec.feature "Homepages", type: :feature do 
    before do 
    Employee.create(username: "username", password: "12345", password_confirmation: "12345") 
    end 

    context "GET/without login" do 
    scenario "works!", js: true do 
     visit root_path 
     fill_in "loginname", with: "username" 
     fill_in "password", with: "12345" 
     click_button('sign_in') 
    end  
    end 
end 

请确认您输入的名字是正确的检查元素来获得输入名称

我觉得

fill_in "loginname", with: "username" 

也许是

fill_in "user[loginname]", with: "username"

正如其他人所指出的，水豚测试应该是类型“功能”而不是“要求”的，但是这不是你的错误的主要原因。您的应用程序代码在模板呈现期间引发异常，然后遇到当前版本的Capybara中的一个错误，它处理的初始化程序需要多个参数。只要你不使用jRuby，你可以将你的Capybara版本锁定到2.10.0，你应该看到你的应用程序正在提升的错误。如果您正在使用JRuby，或者如果你喜欢不锁定的旧版本，您可以指定要使用水豚

gem 'capybara', github: 'teamcapybara/capybara' 

已经错误固定的主分支。

作为一个侧面说明，当你没有真正使用capybara-webkit驱动程序时（因为它目前只支持Capybara 2.7.1），所以你用capybara-webkit标记了这个问题，所以你可能想要将标签更改为水豚。
