为IE添加代码时获得Webdriver错误

Question

我使用Selenium编写了一系列用Python编写的UI测试，打开Chrome运行。我有个程序来安排司机。效果很好。我们现在有必要选择在IE中运行测试。我使用了同样的程序，添加了ie引用而不是铬。现在工作得很好。但是Chrome停止工作了。我不知道为什么。我确认，铬单独工作，并立即中断后，添加IE。我把这两个功能放在下面。

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

def openchrome(userid):
    window_size = '1920,1080'
    chrome_options = Options()
    chrome_options.add_argument('--headless')
    chrome_options.add_argument('--window-size=%s' % window_size)
    chrome_options.add_argument('--no-sandbox')
    driver = webdriver.Chrome(
            input_path + 'chromedriver.exe', options=chrome_options)
    url = settingsfile('url').strip()
    statusmessage(url)
    driver.get(url)
    driver.maximize_window()
    driver.implicitly_wait(3)
    return driver

def openie(userid):
    window_size = '1920,1080'
    ie_options = Options()
    ie_options.add_argument('--headless')
    ie_options.add_argument('--window-size=%s' % window_size)
    ie_options.add_argument('--no-sandbox')
    driver = webdriver.Ie(input_path + 'IEDriverServer.exe', options=ie_options)
    url = settingsfile('url').strip()
    statusmessage(url)
    driver.get(url)
    driver.maximize_window()
    driver.implicitly_wait(3)
    return driver

错误：

Answer 1

您为两个驱动程序导入了具有相同名称的选项模块，为两个IE导入了铬驱动程序。只需在任何应该正确工作的导入中使用“as”一词即可。
