Question

我正在使用Watir-webdriver，Chromedriver（v2.27）和Chrome（v57）进行自动化

我的spec_helper有一行代码为@browser.window.maximize

自从更新到Chrome v57后，由于我收到以下错误，因此不再运行

Asset Section EULA and Intended Use The asset section behaves like eula and intended use EULA and Intended Use clicks Download and sees intended Use
 Failure/Error: @browser.window.maximize

 Selenium::WebDriver::Error::UnknownError:
   unknown error: cannot get automation extension

来自我的#spec_helper：

chrome_prefs = {
'profile' => {
  'default_content_setting_values' => { 'automatic_downloads' => 1 }
  }
}

config.before(:all) do
  @browser = Watir::Browser.new :chrome, :prefs => chrome_prefs, switches: %w(--ignore-certificate-errors --disable-popup-blocking --disable-translate)
  @browser.window.maximize
  @browser.goto site
end

我相当有信心更新到v57造成这种情况。在我更新之前它正在工作，并且 - 现在 - 如果我发表评论@browser.window.maximize它会运行

有什么想法吗？

Answer 1

我遇到了同样的问题，最初通过删除browser.window.maximize并将以下内容添加到交换机来修复它：

client_id

然后在ChromeDriver版本2.28中修复了该问题（最新版本为2.29）。

ChromeDriver 2.28修复说明包括以下内容：

--start-maximized

可以下载here

同时检查测试输出以确保您实际使用的是已下载的新驱动程序，您将看到类似于＆＃34;启动ChromeDriver 2.xx.xxxxxx＆＃34;的内容。您可能有一些指向旧版ChromeDriver的配置。

Watir-webdriver和Chrome57;不能再使用`browser.window`
