无法运行Firefox Selenium IDE导出的pytest脚本，是否缺依赖包？

我使用最新版本（3.17.4）的Firefox Selenium IDE录制测试步骤后，将其导出为Python（pytest）格式脚本，但无法运行且无任何响应。当前环境配置为：pytest 7.2.1、Python 3.9、Spyder 5.4.1（基于Anaconda Navigator 2.3.2）。请问是否缺少相关依赖包？

导出的原始脚本代码：

    actions.move_to_element(element).perform()

一、依赖包与驱动检查 #

1. 确认selenium库安装
   在Anaconda终端执行以下命令安装或更新selenium（推荐4.x版本，与Selenium IDE 3.17.4兼容）：

   conda install selenium
   # 或用pip安装
   pip install selenium
   

2. 安装并配置GeckoDriver
   Firefox需要GeckoDriver驱动才能被selenium调用：
   • 下载与你的Firefox版本匹配的GeckoDriver
   • 把GeckoDriver所在路径添加到系统环境变量PATH；或在代码中指定路径（selenium 4.x推荐用Service类）：

     from selenium.webdriver.firefox.service import Service
     def setup_method(self, method):
         self.driver = webdriver.Firefox(service=Service("你的GeckoDriver绝对路径"))
         self.wait = WebDriverWait(self.driver, 10)
         self.vars = {}
     

二、脚本优化（无响应核心原因） #

录制的脚本存在冗余操作和缺少元素等待的问题，会导致程序因元素未加载完成而卡住：

1. 添加显式等待：所有元素操作前，用WebDriverWait等待元素可见或可点击，避免页面未加载完成就执行操作。
2. 移除冗余操作：删除重复点击、无效鼠标操作等无意义步骤。
3. 修正输入错误：原脚本中第9行密码输入secret_aurce是错误的，直接输入正确密码secret_sauce。

优化后的可运行脚本：

# Generated by Selenium IDE（优化版）
import pytest
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions
from selenium.webdriver.support.wait import WebDriverWait
from selenium.webdriver.firefox.service import Service

class TestSauceTest1():
  def setup_method(self, method):
    # 替换为你的GeckoDriver路径
    self.driver = webdriver.Firefox(service=Service("C:/geckodriver.exe"))
    # 初始化显式等待，超时10秒
    self.wait = WebDriverWait(self.driver, 10)
    self.vars = {}
  
  def teardown_method(self, method):
    self.driver.quit()
  
  def test_sauceTest1(self):
    # 打开目标网站
    self.driver.get("https://www.saucedemo.com/")
    self.driver.set_window_size(550, 680)
    
    # 等待用户名输入框并输入内容
    username_input = self.wait.until(expected_conditions.visibility_of_element_located((By.CSS_SELECTOR, "*[data-test=\"username\"]")))
    username_input.send_keys("standard_user")
    
    # 等待密码输入框并输入正确密码
    password_input = self.wait.until(expected_conditions.visibility_of_element_located((By.CSS_SELECTOR, "*[data-test=\"password\"]")))
    password_input.send_keys("secret_sauce")
    
    # 等待登录按钮可点击并点击
    login_btn = self.wait.until(expected_conditions.element_to_be_clickable((By.CSS_SELECTOR, "*[data-test=\"login-button\"]")))
    login_btn.click()
    
    # 等待添加购物车按钮并点击
    add_cart_btn = self.wait.until(expected_conditions.element_to_be_clickable((By.CSS_SELECTOR, "*[data-test=\"add-to-cart-sauce-labs-backpack\"]")))
    add_cart_btn.click()
    
    # 等待购物车链接并点击
    cart_link = self.wait.until(expected_conditions.element_to_be_clickable((By.LINK_TEXT, "1")))
    cart_link.click()
