Question

我试图使用capybara＆amp; amp;使用黄瓜的硒webdriver。浏览器已启动，但无法加载网址。以下是我的env.rb文件

begin require 'rspec/expectations'; 
rescue LoadError; 
require 'spec/expectations'; 
end

require 'capybara'
require 'capybara/dsl'
require 'capybara/cucumber'
require 'capybara/session'
require 'selenium-webdriver'


Capybara.register_driver :selenium do |app|

    profile = Selenium::WebDriver::Firefox::Profile.new

    profile["network.proxy.type"] = 1 # manual proxy config
    profile["network.proxy.http"] = "proxybank.icici.net"
    profile["network.proxy.http_port"] = 8080

    profile.native_events = true 

    Capybara::Selenium::Driver.new(app, :browser => :firefox, :profile => profile)

  end



app_host = "https://mobilebanking.icici.com"

Capybara.app_host = app_host

Capybara.run_server = true

Capybara.default_driver = :selenium

我得到的错误低于

Answer 1

编辑： server_boot_timeout已在Capybara 2中删除。

对于Capybara 2
您可以尝试添加wait.until并查看是否有帮助。您需要在文件顶部require 'selenium-webdriver'。

更改以下行：

Capybara::Selenium::Driver.new(app, :browser => :firefox, :profile => profile)

到此：

capybara_driver = Capybara::Selenium::Driver.new(app, :browser => :firefox, :profile => profile)
driver = capybara_driver.browser

wait = Selenium::WebDriver::Wait.new(:timeout => 300)
wait.until { driver.title.downcase.start_with? "my page title" }

如果这不起作用，你也可以尝试使用普通的老红宝石睡眠。

sleep(5.minutes)

对于Capybara＆lt; 2
尝试增加Capybara.server_boot_timeout值。在env.rb文件中使用以下内容（如果该行不存在，请添加该行）。

Capybara.server_boot_timeout = 300 # 5 mins

不要将此错误与运行测试时实际使用的Capybara.default_wait_time相提并论。此外，这两个属性都采用seconds中的值。

在调用实际的Web驱动程序之前更新这些值。可能就在所有require陈述之后。

Answer 2

如果您使用app_host =“https://mobilebanking.icici.com”

Capybara.app_host = app_host

然后您必须将Capybara.run_server设置为false。这是因为如果Capybara.run_server为true，那么它将在您计算机上的默认ROR服务器上托管应用程序，然后从浏览器访问localhost以打开Web应用程序。

因此，在Capybara.run_server = false中设置env.rb可以解决问题。

Selenium webdriver无法在基于capybara的框架中打开网页
