如何访问我在 Selenium Webdriver 中添加的 Firefox 扩展? [英] How to access Firefox Extension I added in Selenium Webdriver?

问题描述

我知道您可以加载现有的 Firefox 配置文件，或者使用 selenium-webdriver gem 中的 Ruby 绑定创建一个，如下所述:

I know that you can load up either an existing Firefox profile, or create one using Ruby Bindings in the selenium-webdriver gem, as described here:

http://code.google.com/p/selenium/wiki/RubyBindings

然后使用 add_extension 将任意数量的 Firefox 扩展添加到实例中，然后呢?我正在使用的扩展程序的窗口在测试期间没有出现.如何使用扩展程序?

And then use add_extension to add any number of Firefox extensions to the instance, but then what? The window for the extension I'm using does not appear during the test. How do I use the extension?

有没有办法在驱动打开 Firefox 时默认打开扩展?

Is there a way to have the extension be open by default when the driver opens Firefox?

这是我正在使用的代码:

Here is the code I'm using:

#!/usr/bin/env ruby
require "rubygems"
require "selenium-webdriver"

default_profile = Selenium::WebDriver::Firefox::Profile.from_name "default"
default_profile.add_extension("/Users/******/Library/Application Support/Firef
ox/Profiles/wvon3h99.default/extensions/{9c51bd27-6ed8-4000-a2bf-36cb95c0c947}.
xpi")

driver = Selenium::WebDriver.for(:firefox, :profile => default_profile)
driver.navigate.to "http://google.com"

element = driver.find_element(:name, 'q')
element.send_keys "Hello WebDriver!"
element.submit

puts driver.title

driver.quit

推荐答案

这取决于扩展.通常，在创建 FF 配置文件时，可以通过设置适当的属性(您可以在 about:config 中找到的属性)在某种程度上控制扩展程序的行为.例如，在 FF 启动后默认打开 Firebug 窗口，我将在我的代码中包含以下行:

It depends on extension. Usually the extension's behaviour can be to some extent controlled by setting appropriate properties (the ones you can find in about:config) when creating an FF profile. For instance to have Firebug window open by default after FF starts I would include the following line in my code:

default_profile["extensions.firebug.allPagesActivation"] = true

我使用的扩展程序通常具有某种自动导出功能，可以自动将数据发送到服务器或将其保存在磁盘上.恐怕无法使用 WebDriver 控制扩展，因此并非所有扩展都可用于自动化测试.

The extensions I use usually have some kind of auto-export feature that automatically sends data to server or saves it on disk. I am afraid there is no way of controlling an extension with WebDriver so not all extensions will be usable in automated tests.
