Rails Rspec IntegrationTest Capybara
Rails Rspec IntegrationTest Capybara
提问于 2016-11-29 19:42:32
我已经开始通过Rspec (Capybara)测试我的应用程序。我是这样做的：
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“，我必须首先创建一个employee。问题是，如果我运行'rake spec:request‘，我会得到这个错误：
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)

我不确定，但我认为如果type = feature会更好
示例
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请通过检查元素来获取输入名称，以确保您的输入名称正确
我认为
fill_in "loginname", with: "username"也许是吧
fill_in "user[loginname]", with: "username"Stack Overflow用户

正如其他人所说，Capybara测试的类型应该是'feature‘而不是'request'，然而这并不是导致错误的主要原因。你的应用程序代码在模板渲染过程中会引发异常，然后你会在当前版本的Capybara中遇到一个处理异常的错误，这些异常的初始化器会接受多个参数。只要你没有使用jRuby，你就可以将你的Capybara版本锁定到2.10.0，你应该会看到你的应用程序引发的正确错误。如果您使用的是jRuby，或者您不想锁定到旧版本，则可以指定使用Capybara的主分支
gem 'capybara', github: 'teamcapybara/capybara'它已经修复了错误。
作为附注，当您实际上没有使用capybara-webkit驱动程序时，您已经用capybara-webkit标记了这个问题(因为它目前只支持capybara 2.7.1 )，所以您可能想要将标记更改为仅仅是Capybara。
