如何在水豚和硒中打开浏览器

Question

describe 'Downloads', js: true do

context ' compress zip and download file' do
  before do
    Capybara.current_driver = :selenium
    session = Capybara::Session.new(:selenium)
    session.visit '/users/sign_in'
    find('#tab_signin').click
    within("#new_user") do
      fill_in 'user_login', :with => '[e-mail]'
      fill_in 'user_password', :with => 'password'
    end
    click_button 'Sign in'
end

it 'downloads the project and navigates to downloads page' do
  visit 'some/path'
  within '.create-download' do
    find(:select).find("option[value='zip']").select_option
  end
  sleep 3
  page.should have_css('#download-modal.in')
end

Capybara.javascript_driver = :selenium
Capybara.register_driver :selenium do |app|
  profile = Selenium::WebDriver::Firefox::Profile.new
  Capybara::Selenium::Driver.new(app, :browser => :firefox, :profile => profile)
end

不仅浏览器没有打开，而且测试失败，输出如下：

Failure/Error: visit '/users/sign_in'
 ArgumentError:
   unknown option: {:resynchronize=>true}

所以经过大量的工作，我终于想通了。感谢@Raj关于将配置信息放在哪里的建议。特性/support/env.rb是针对cucumber的，我使用的是RSpec。

我读到的大多数关于selenium和capybara的文章都告诉我在块的开头使用js:true选项，但这不起作用。一旦我将其更改为feature:true，它就起作用了。我的最终解决方案如下所示：

describe 'Downloads', feature: true do

context 'compress zip and download file' do
before do

  visit '/users/sign_in'
  find("a[href$='signin']").click
  within("#new_user") do
    fill_in 'user_login', :with => '[e-mail]'
    fill_in 'user_password', :with => 'password'
  end
  click_button 'Sign in'
end

it 'downloads the project and navigates to downloads page' do
  visit 'some/path'
  within '.create-download' do
    find(:select).find("option[value='zip']").select_option
  end
  sleep 3
  page.should have_css('#download-modal.in')
end
end
end

然后我的spec_helper.rb看起来像：

Capybara.register_driver :selenium do |app|
  profile = Selenium::WebDriver::Firefox::Profile.new
  Capybara::Selenium::Driver.new( app, :profile => profile)
end
Capybara.default_wait_time = 10
Capybara.current_driver = :selenium
Capybara.app_host = 'http://localhost:3000'
