如何从Selenium IDE创建可用的Selenium WebDriver python脚本？

Question

我是selenium的新手，我正尝试使用Selenium IDE（2.9.0）创建第一个单击记录脚本作为基本脚本，然后使用Selenium WebDriver（2.48.0）对其进行完善。

我记录了一个工作脚本（请参阅本问题末尾的附件），并将其导出为“ python 2 / unittest / WebDriver”。但是，源代码清楚地表明它存在一些问题（带有令人不适的“ ERROR”语句的注释行）：

# -*- coding: utf-8 -*-
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import Select
from selenium.common.exceptions import NoSuchElementException
from selenium.common.exceptions import NoAlertPresentException
import unittest, time, re

class Test1(unittest.TestCase):
    def setUp(self):
        self.driver = webdriver.Firefox()
        self.driver.implicitly_wait(30)
        self.base_url = "http://ironspider.ca/"
        self.verificationErrors = []
        self.accept_next_alert = True

    def test_1(self):
        driver = self.driver
        driver.get(self.base_url + "/frames/frames_example1/advanced.htm")
        # ERROR: Caught exception [ERROR: Unsupported command [selectFrame | content | ]]
        self.assertEqual("The Eve of the War", driver.find_element_by_css_selector("h2").text)
        # ERROR: Caught exception [ERROR: Unsupported command [selectWindow | name=menu | ]]
        driver.find_element_by_link_text("Chapter 2").click()
        # ERROR: Caught exception [ERROR: Unsupported command [selectWindow | name=content | ]]
        self.assertEqual("The Falling Star", driver.find_element_by_css_selector("h2").text)

    def is_element_present(self, how, what):
        try: self.driver.find_element(by=how, value=what)
        except NoSuchElementException: return False
        return True

    def is_alert_present(self):
        try: self.driver.switch_to_alert()
        except NoAlertPresentException: return False
        return True

    def close_alert_and_get_its_text(self):
        try:
            alert = self.driver.switch_to_alert()
            alert_text = alert.text
            if self.accept_next_alert:
                alert.accept()
            else:
                alert.dismiss()
            return alert_text
        finally: self.accept_next_alert = True

    def tearDown(self):
        self.driver.quit()
        self.assertEqual([], self.verificationErrors)

if __name__ == "__main__":
    unittest.main()

运行此代码也不起作用。错误是：

ERROR: test_1 (__main__.Test1)

我是否必须手动修复所有错误（如果是，如何解决？）？“ Selenium IDE”不能为WebDriver 导出脚本的有效版本吗？我需要安装其他东西吗？我的一般方法完全错误吗？也许我应该使用硒以外的其他东西？

原来这里是工作的硒IDE测试用例脚本。

不幸的是，Selenium IDE 并不是一个完美的自动化测试工具，只能作为初学者的开始，这就是为什么它生成的大部分代码可能包含过时的或错误的代码（在您的情况下是错误的命令）。您需要手动处理每个异常。

我知道它看起来很蹩脚，但是请看一下Selenium Python 文档

它将帮助您以正确的形式重写这些方法。希望这对你有帮助
