Capybara +具有数据库清理程序的Poltergeist找不到FactoryGirl记录 [英] Capybara + Poltergeist with Database-cleaner not finding FactoryGirl records

问题描述

我正在编写集成测试并使用 FactoryGirl 创建记录。当测试具有 js：true （使用Poltergeist）时，我的控制器抛出 RecordNotFound ，即使在非-js测试（无Poltergeist）。

I'm writing integration tests and creating records with FactoryGirl. My controllers are throwing RecordNotFound when the test has js: true (with Poltergeist) even though they are found in a non-js test (without Poltergeist).

我确实将 use_transactional_fixtures 设置为 false 和 DatabaseCleaner.strategy 设置为：truncation ，这似乎涵盖了有关此问题的所有现有SO问题。我尝试用Selenium（使用Firefox）代替Poltergeist，但是得到了相同的结果。 ETA 我用RSpec-Rails 3.3.3，Capybara 2.4.4，Poltergeist 1.6.0，PhantomJS 1.9.8，Database Cleaner 1.4.1开始了一个新的Rails 4.2.3项目。在测试新的未经编辑的脚手架时。

I do have use_transactional_fixtures set to false and DatabaseCleaner.strategy set to :truncation, which seemingly covers every existing SO question on this issue. I tried substituting Selenium (with Firefox) for Poltergeist but I get the same result. ETA I started a fresh Rails 4.2.3 project with RSpec-Rails 3.3.3, Capybara 2.4.4, Poltergeist 1.6.0, PhantomJS 1.9.8, Database Cleaner 1.4.1 and get the same results when testing a new, unedited scaffold.

为什么Poltergeist找不到我的记录？由于我已经提出了任何建议，因此会有帮助在这里呆了几个小时。

Why aren't my records found by Poltergeist? Any suggestions would be helpful, since I've been at this for hours.

前两个测试通过，而最后一个失败在第二行使用 RecordNotFound ：

The first two tests pass while the last fails on the second line with RecordNotFound:

require 'spec_helper'

before :each do
  @vehicle = FactoryGirl.create :vehicle
end

it "should work on vehicle path" do
  visit vehicle_path(@vehicle)
  expect(page).to have_content @vehicle.name
end

describe "with js", js: true do
  it "should work on root path" do
    visit root_path
    expect(page).to have_content "My Root"
  end

  it "should work on vehicle path" do
    expect(Vehicle.find(@vehicle.to_param)).to be_present # no error
    visit vehicle_path(@vehicle) # error: ActiveRecord::RecordNotFound in controller from Vehicle.find (same as above line)
    expect(page).to have_content @vehicle.name
  end
end

这是我精简的spec_helper.rb：

Here is my pared-down spec_helper.rb:

require 'rubygems'
ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'factory_girl_rails'
require 'database_cleaner'
require 'capybara/rails'
require 'capybara/rspec'
require 'capybara/poltergeist' 

ActiveRecord::Migration.check_pending! if defined?(ActiveRecord::Migration)

Capybara.register_driver :poltergeist do |app|
  Capybara::Poltergeist::Driver.new app, window_size: [1600, 1200], js_errors: false
end

RSpec.configure do |config|
  config.use_transactional_fixtures = false
  config.order = "random"

  Capybara.javascript_driver = :poltergeist
  config.include Capybara::DSL

  config.before(:suite) do
    DatabaseCleaner.clean_with(:truncation) # moving to before :each doesn't help
    DatabaseCleaner.strategy = :truncation # moving to before :each doesn't help
  end

  config.around :each do |example| # refactoring as before/after with .start/.clean doesn't help
    DatabaseCleaner.cleaning { example.run }
  end
end

推荐答案

我创建了一个新项目，并基本上复制了您的设置，它看起来运行良好-您可以看到在这里- http://github.com/twalpole/demo_truncation -不确定您的设置有什么区别并尝试使用新的应用程序

I created a fresh project and basically copied over your setup, and it appears to work fine -- you can see it here - http://github.com/twalpole/demo_truncation - not sure what the difference with your setup and attempt at a fresh app are
