将Chrome设置为RSpec/Capybara的默认浏览器

Question

我在使用Chrome在Ubuntu 13.10 64位上使用RSpec/Capybara时遇到了一些麻烦.默认情况下它启动Firefox - 我们试图通过多种方式改变它,包括:

/home/.../xxx_spec.rb:8:in `<top (required)>': undefined local variable or method `“chromedriver”' for main:Object (NameError)

我们还尝试过:

require 'capybara/rspec'
require 'rspec'
require 'selenium-webdriver'

Capybara.register_driver :selenium do |app|
  Capybara::Selenium::Driver.new(app, :browser => :chrome)
end

/home/ubuntu/.rbenv/versions/2.0.0-p247/lib/ruby/gems/2.0.0/gems/selenium-webdriver-2.39.0/lib/selenium/webdriver/chrome/service.rb:50:in `start': unable to connect to chromedriver http://127.0.0.1:9515 (Selenium::WebDriver::Error::WebDriverError)

使用Chrome需要另外一步吗？我是Selenium的新手.

Answer 1

如果我没记错的话:

我chromedriver从此资源https://code.google.com/p/selenium/wiki/ChromeDriver下载了最新版本

然后插入 spec_helper.rb

Capybara.register_driver :chrome do |app|
  Capybara::Selenium::Driver.new(app, :browser => :chrome)
end

Capybara.javascript_driver = :chrome

它对我有用

Answer 2

添加此gem以Gemfile安装和更新chromedriver.

gem "chromedriver-helper", "1.0.0"

请参阅https://github.com/flavorjones/chromedriver-helper.以前答案的评论中列出的错误已得到修复.

然后将其添加到spec_helper.rb:

Capybara.register_driver :selenium do |app|
  Capybara::Selenium::Driver.new(app, browser: :chrome)
end

而已.

Answer 3

添加gem "chromedriver-helper"到Gemfile并运行bundle

在下面的块spec_helper.rb外面还包括下面这行代码Rspec.configure.

Capybara.register_driver :selenium do |app|
  Capybara::Selenium::Driver.new(app, browser: :chrome)
end

最重要的是,不要忘记require 'capybara'在spec_helper.rb

这将解决问题.:)
