Rails Rspec集成测试水豚

Question

我已经开始通过Rspec（水豚）测试我的应用程序。 这就是我的做法：

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”，因此我必须首先创建一个雇员。 问题是，如果我运行“ rake spec：requests”，则会收到以下错误消息：

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

我不确定，但我认为类型=功能更好

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

请通过inspect元素确保您输入的名称正确，以获取输入名称

我认为

fill_in "loginname", with: "username"

也许是

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

正如其他人所述，水豚测试应该是“功能”类型而不是“请求”类型，但这不是造成错误的主要原因。 您的应用代码在模板渲染期间引发了异常，然后您遇到了当前版本的Capybara中的一个错误，该错误正在处理其初始化程序采用多个参数的异常。 只要您不使用jRuby，就可以将Capybara版本锁定为2.10.0，并且应该看到应用程序引发的正确错误。 如果您使用的是jRuby，或者您不想锁定到较旧的版本，则可以指定使用Capybara的master分支

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

已修复的错误。

附带说明一下，当您实际上不使用capybara-webkit驱动程序时（因为它目前仅支持Capybara 2.7.1），您已经用capybara-webkit标记了这个问题，因此您可能需要更改标记到水豚。
