运行 rspec 请求规范未找到存在的记录

Question

我正在为我的一个项目使用 Rails 5 (Ruby 2.3.3)。我已经使用 Capybara (capybara-wekbit) 和 RSpec.

编写了一个测试

我正在使用请求规范测试控制器操作。这是控制器

class TimelineController < ApplicationController
  before_action :set_child
  before_action :authenticate_user!

  def index    
  end

  private
  def set_child
    @child = Child.find(params[:child_id])
  end
end

这是测试

RSpec.describe "Timeline", type: :request do
  it 'can visit the child timeline path', js: true do
    child = FactoryGirl.create(:valid_child)
    sign_in child.caregiver.user
    p child
    visit child_timeline_path(child)
  end
end

p child 行打印以下内容

#<Child id: 1, first_name: nil, last_name: nil, dob: "2018-06-21 00:00:00", caregiver_id: 1, doctor_id: 1, preferred_name: nil, gender: nil, street: nil, city: nil, province: nil, postal: nil, country: nil, email: nil, caregiver_relationship: nil, phone: nil, created_at: "2018-06-21 20:21:16", updated_at: "2018-06-21 20:21:16", avatar: nil, time_zone: "Pacific Time (US & Canada)", other_relationship: nil>

但是，当 RSpec 调用 visit child_timeline_path(child) 时，测试失败并出现以下错误：

  1) Timeline can visit the child timeline path
     Failure/Error: @child = Child.find(params[:child_id])

     ActiveRecord::RecordNotFound:
       Couldn't find Child with 'id'=1

我看到打印了id的子记录。但是，rspec 无法找到该记录。

这里是子工厂（FactoryGirl）

FactoryGirl.define do
  factory :valid_child, class: "Child" do |f|
    f.association :doctor
    f.association :caregiver
    f.dob Date.today
  end
end

此外，如果有帮助，这里是 spec_helper.rb

require 'capybara/rspec'

Dir["./spec/support/**/*.rb"].sort.each {|f| require f}

RSpec.configure do |config|
  config.include FactoryGirl::Syntax::Methods
  config.include Capybara::DSL
  config.include Devise::Test::IntegrationHelpers, type: :request

  Capybara.javascript_driver = :webkit

  # rspec-expectations config goes here. You can use an alternate
  # assertion/expectation library such as wrong or the stdlib/minitest
  # assertions if you prefer.
  config.expect_with :rspec do |expectations|
      expectations.include_chain_clauses_in_custom_matcher_descriptions = true
  end

  # rspec-mocks config goes here. You can use an alternate test double
  # library (such as bogus or mocha) by changing the `mock_with` option here.
  config.mock_with :rspec do |mocks|
    mocks.verify_partial_doubles = true
  end

  # This option will default to `:apply_to_host_groups` in RSpec 4 (and will
  # have no way to turn it off -- the option exists only for backwards
  # compatibility in RSpec 3). It causes shared context metadata to be
  # inherited by the metadata hash of host groups and examples, rather than
  # triggering implicit auto-inclusion in groups with matching metadata.
  config.shared_context_metadata_behavior = :apply_to_host_groups

  config.before(:suite) do
    DatabaseCleaner.strategy = :transaction
    DatabaseCleaner.clean_with(:truncation)
  end

  config.around(:each) do |example|
    DatabaseCleaner.cleaning do
      example.run
    end
  end
end

Answer 1

DatabaseCleaner.strategy = :transaction 表示被测应用和测试需要共享相同的数据库连接才能查看创建的记录。不幸的是，Rails 5（在 Rails 5.1+ 中修复，根本不需要 database_cleaner）在线程之间并不真正支持。这意味着当运行ning js: true 功能测试（运行应用程序在单独的线程中）时，您需要将策略更改为 :t运行cation 或 :deletion .建议的 DatabaseCleaner 配置准确显示了所需内容 - https://github.com/DatabaseCleaner/database_cleaner#rspec-with-capybara-example

Running rspec request spec does not find the record which exists
