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maximize

---

另一方面，我还建议升级到最新的chromedriver分期付款v2.31（）。

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。因此，你的

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

在这种情况下总是会失败，因为驾驶员不知道最大化哪个窗口，因为没有可用的窗口

试试这样的

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

---

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，会发现此错误：

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

有关更多详细信息，请参阅和

IMO，没有最佳实践，但您可以始终考虑使用<代码>选项类来最大化Chrome浏览器窗口如下：

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()

我们能看看你试过的代码吗？我试过chromedriver 2.31和2.30，同样的错误encountered@xiaona2016cao尝试执行其他用户建议的操作，并编辑出maximize调用。谢谢，我使用setSize方法替换maximize（）
