python selenium 我在我的课上遇到了多个错误？

Question

我是 Python 新手，我正在尝试从 robotsframework 修改 SeleniumLibrary 以满足我自己的需求。不幸的是，我遇到了多个错误，我不知道为什么。

有多种函数可以通过二进制路径和无头选项调用不同的浏览器。

import os

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities



DEFAULT_BROWSR = 'chrome'

DRIVERS_PATH = os.path.join( os.getcwd() , "\drivers\\" )

BROWSER_NAMES = {
    'ff': "_make_ff",
    'firefox': "_make_ff",

这个函数应该打开一个浏览器，它会调用默认的 chrome 驱动：

driver().create()

正如 cmets 中强调的那样，此类问题可以通过使用具有调试功能的正确配置的 Python IDE 轻松解决。有几个不错的，开源的和商业的。

在这种特殊情况下，您的脚本有两个问题：

缺少导入：

from robot.utils import is_falsy

函数需要重写，因为 func_name 需要是不同的值。

""" Return browser driver path """
def _get_driver_path(self,browser_name):
    try:
        #func_name = self._get_driver_creation_function(browser_name)
        driver_path = os.path.join(DRIVERS_PATH , BROWSER_PATHS[BROWSER_NAMES[browser_name]])
    except KeyError:
        raise ValueError(browser_name + " is not a supported browser.")
    return driver_path
