Question

我有一个Rails应用程序，已通过RSpec和Capybara进行了测试

我有以下测试：

<a class="btn btn-primary" href="{{route('payments.viewpayment',$vehicles->id)}}" role="button">Go Premium</a>
<form method="post" action="{{route('payments.payment', ['id' => $vehicles->id])}}">
{{csrf_field()}}

我在浏览器中具有以下链接：

context 'destroy user' do
    scenario "should be successful" do
      user = User.create(first_name: 'John', last_name: 'Doe', email: 'john.doe@example.com')
      visit users_path

      click_link 'Destroy'
      # expect { click_link 'Destroy' }.to change(User, :count).by(-1)

      expect(page).to have_content 'User was successfully destroyed'
    end
  end

我运行测试，测试通过。它不应该过去，因为在调用该操作之前我有警报窗口。

我已安装

<%= link_to "Destroy", user_path(user), method: :delete, data: { confirm: "Are you sure?" } %>

因为我想测试JS，但不幸的是测试没有失败。

rails_helper.rb

brew cask install chromedriver

一旦测试失败，我将通过以下方式改进测试：

# This file is copied to spec/ when you run 'rails generate rspec:install'
require 'spec_helper'
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?

# Add additional requires below this line. Rails is not loaded until this point!
require 'rspec/rails'
require 'capybara/rails'

# Capybara.default_driver = :selenium_chrome ### not working

# require "support/factory_bot"
Dir[Rails.root.join('spec/support/**/*.rb')].each { |f| require f }

begin
  ActiveRecord::Migration.maintain_test_schema!
rescue ActiveRecord::PendingMigrationError => e
  puts e.to_s.strip
  exit 1
end
RSpec.configure do |config|
  # Remove this line if you're not using ActiveRecord or ActiveRecord fixtures
  config.fixture_path = "#{::Rails.root}/spec/fixtures"

  config.use_transactional_fixtures = true

  config.infer_spec_type_from_file_location!

  # Filter lines from Rails gems in backtraces.
  config.filter_rails_from_backtrace!
end

我认为我的问题是，我不知道将线放在何处：

Capybara.default_driver =：selenium_chrome ###不起作用

在哪里为水豚的配置创建文件？在官方文档中，他们在lib / capybara.rb

中说

我在那里尝试过，但出现错误：

accept_confirm do
    click_link 'Destroy'
end

您没有显示Capybara配置（default_driver / javascript_driver），并且测试中也没有js元数据，这暗示您可能正在使用rack_test驱动程序以运行您的测试。 rack_test驱动程序不支持JS，因此将完全忽略JS确认。如果要测试JS行为，则需要确保使用的是实际支持JS的驱动程序-请参见https://github.com/teamcapybara/capybara#drivers和https://github.com/teamcapybara/capybara#using-capybara-with-rspec

销毁方法测试不会失败，尽管使用了JavaScript警报窗口
