Question

我已经开始通过Rspec（Capybara）测试我的应用程序。我就是这样做的：

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”，我必须先创建一名员工。问题是，如果我运行'rake spec：requests'，我会收到这个错误：

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

我不确定，但如果type = feature

，我认为会更好

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元素确保您的输入名称正确，以获取输入名称

我认为

fill_in "loginname", with: "username"

也许是

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

正如其他人所说，Capybara测试的类型应该是＆＃39;特征＆＃39;但请求＆＃39;然而，这不是导致错误的主要原因。您的应用程序代码在模板呈现期间引发异常，然后您在当前版本的Capybara中遇到错误，并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版本锁定到2.10.0，您应该会看到应用程序正在引发的错误。如果您使用的是jRuby，或者您不想锁定旧版本，则可以指定使用Capybara的主分支

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

修复了错误。

作为旁注，当您未实际使用capybara-webkit驱动程序时（因为它目前仅支持Capybara 2.7.1），您已使用capybara-webkit标记了此问题，因此您可能想将标签更改为只是水豚。
