我无法让 Capybara 在一个规范中进行超过一页访问的会话。我熟悉 Capybara 的驱动程序可能使用不同的数据库连接的概念，但我所做的任何事情（包括不使用 :js => true）似乎都没有改变任何东西。
我只是想访问一个需要用户身份验证的页面。它在第一次访问时成功。当我第二次访问它时它失败了。（当然，当我在开发中手动测试时，这一切都有效。）代码：
activity_areas_spec.rb
require "rails_helper"
RSpec.feature "Activity areas", :type => :feature do
user = FactoryGirl.create(:user)
before(:each) do
login_as(user, :scope => :user)
end
after(:each) do
Warden.test_reset!
end
...
feature "displays activities shared", :js => true do
scenario "to public" do
visit area_activities_path
expect(page).to have_content I18n.t('pages.activity.areas.title') #passes
visit area_activities_path
expect(page).to have_content I18n.t('pages.activity.areas.title') #fails -- user is redirected to login page.
end
end
end
#rails_helper.rb
ENV['RAILS_ENV'] ||= 'test'
require File.expand_path('../../config/environment', __FILE__)
# Prevent database truncation if the environment is production
abort("The Rails environment is running in production mode!") if Rails.env.production?
require 'rspec/rails'
require 'spec_helper'
require 'capybara/rails'
require 'devise'
require 'support/controller_macros'
include Warden::Test::Helpers
Warden.test_mode!
ActiveRecord::Migration.maintain_test_schema!
RSpec.configure do |config|
# Factory girl
config.include FactoryGirl::Syntax::Methods
# Make routes available in specs
config.include Rails.application.routes.url_helpers
# Capybara
config.include Capybara::DSL
# To get Devise test helpers
config.include Devise::TestHelpers, :type => :controller
config.extend ControllerMacros::DeviseHelper, :type => :controller
config.include ControllerMacros::AttributeHelper, :type => :controller
config.use_transactional_fixtures = false
config.infer_spec_type_from_file_location!
config.filter_rails_from_backtrace!
# Database cleaner gem configurations
config.before(:suite) do
DatabaseCleaner.clean_with(:truncation)
end
config.before(:each) do
DatabaseCleaner.strategy = :transaction
end
config.before(:each, :js => true) do
DatabaseCleaner.strategy = :truncation
end
config.before(:each) do
DatabaseCleaner.start
end
config.after(:each) do
DatabaseCleaner.clean
end
end
由于我对 Capy 可能使用不同的数据库连接这一事实很敏感，因此我尝试按照 DatabaseCleaner 对 tee 的建议代码来代替上述 DatabaseCleaner 命令：
config.before(:suite) do
if config.use_transactional_fixtures?
raise(<<-MSG)
Delete line `config.use_transactional_fixtures = true` from rails_helper.rb
(or set it to false) to prevent uncommitted transactions being used in
JavaScript-dependent specs.
During testing, the app-under-test that the browser driver connects to
uses a different database connection to the database connection used by
the spec. The app's database connection would not be able to access
uncommitted transaction data setup over the spec's database connection.
MSG
end
DatabaseCleaner.clean_with(:truncation)
end
config.before(:each) do
DatabaseCleaner.strategy = :transaction
end
config.before(:each, type: :feature) do
driver_shares_db_connection_with_specs = Capybara.current_driver == :rack_test
if !driver_shares_db_connection_with_specs
DatabaseCleaner.strategy = :truncation
end
end
config.before(:each) do
DatabaseCleaner.start
end
config.append_after(:each) do
DatabaseCleaner.clean
end
#spec_helper.rb
require 'factory_girl_rails'
require "capybara/rspec"
require 'sidekiq/testing'
RSpec.configure do |config|
config.expect_with :rspec do |expectations|
expectations.include_chain_clauses_in_custom_matcher_descriptions = true
end
config.mock_with :rspec do |mocks|
mocks.verify_partial_doubles = true
end
end
我很容易感到困惑，非常感谢以简单的术语提供的任何帮助。如果您需要任何其他文件，请告诉我。
