问题描述

我最近将chrome版本升级到了60，并将chromedriver升级到了版本2.31.当我尝试最大化浏览器窗口时，便发布了以下异常消息.

I recently upgraded my chrome version to 60 and chromedriver to version 2.31. Post that I have started getting the following exception when I try to do a maximize of the browser window.

driver.driver.manage().window().maximize()

我使用Geb上的ChromeDriver在无头模式下运行测试.

I run my tests in headless mode using ChromeDriver on Geb.

• Chrome版本-60.0.3112.78
• chromedriver版本-2.31.488763
• 操作系统-Ubuntu 14.04.4 LTS
• 硒版本-2.53.1
• WebDriver语言绑定
• Geb-0.13.1

推荐答案

由于您以无头模式运行测试，因此没有可用的active浏览器窗口.因此，您的

Since you're running tests in a headless mode, there is no active browser window available. As such your

   driver.driver.manage().window().maximize()

在这种情况下总是会失败，因为驱动程序不知道要最大化哪个窗口，因为没有可用的窗口.

would always fail in such situations because the driver doesn't know which window to maximize since there aren't any available.

您可以按照@DebanjanB的说明进行操作，也可以使用特定的屏幕尺寸(例如1440x900等)启动无头浏览器，执行类似的操作

You can either follow what @DebanjanB has mentioned or you can start the headless browser with a specific screen size like 1440x900 etc, doing something like this

 driver.manage().window().setSize(new Dimension(1440, 900));
