Answer 1

正如错误日志所示

failed to change window state to normal, current state is maximized

我建议在iNotesTestCase.testSetUp中，在调用setSize方法之前删除调用最大化。

另一方面，我还建议升级到最新的chromedriver分期付款v2.31（https://sites.google.com/a/chromium.org/chromedriver/downloads）。

Answer 2

由于您在无头模式下运行测试，因此没有可用的活动浏览器窗口。就这样你的

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

在这种情况下，

总是会失败，因为驱动程序并不知道哪个窗口要最大化，因为没有任何可用的窗口。

尝试这样的事情

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

Answer 3

错误堆栈跟踪将其全部表示为：

org.openqa.selenium.WebDriverException: unknown error: failed to change window state to normal, current state is maximized

当您尝试通过以下方式最大化Chrome浏览器时会出现此错误：

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

您可以浏览GitHub discussion和chromedriver issue了解详情。

IMO，没有最佳做法，但您始终可以考虑使用Options类来最大化Chrome浏览器窗口，如下所示：

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

options = Options()
options.add_argument("start-maximized")
options.add_argument("disable-infobars")
options.add_argument("--disable-extensions")
driver = webdriver.Chrome(chrome_options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
driver.get('https://www.google.co.in')
print("Page Title is : %s" %driver.title)
driver.quit()

使用Chrome60启动selenium chromedriver失败
