【问题描述】：

我有一个 Selenium Python 测试套件。它开始运行，但几分钟后抛出以下错误：

Exception AttributeError: "'Service' object has no attribute 'process'" in <bound method Service.__del__ of <selenium.webdriver.ie.service.Service object at 0x0000000002610DD8>> ignored

我的测试套件实现是：

import unittest
from htmlTestRunner2 import HTMLTestRunner
import os
import Regression_TestCase.RegressionProject_TestCase2


# get the directory path to output report file
#result_dir = os.getcwd()
result_dir = r"E:\test_runners\selenium_regression_test_5_1_1\ClearCore - Regression Test\TestReport"

# get all tests from SearchProductTest and HomePageTest class
search_tests = unittest.TestLoader().loadTestsFromTestCase(Regression_TestCase.RegressionProject_TestCase2.RegressionProject_TestCase2)

# create a test suite combining search_test
re_tests = unittest.TestSuite([search_tests])

# open the report file
outfile = open(result_dir + "\TestReport.html", "w")

# configure HTMLTestRunner options
runner = HTMLTestRunner.HTMLTestRunner(stream=outfile,
                                       title='Test Report',
                                       description='Smoke Tests')

# run the suite using HTMLTestRunner
runner.run(re_tests)

谁能帮忙解释为什么这个错误会阻止我的测试套件运行？我该如何解决？

【参考方案1】：

如果您已经安装了 selenium，并且假设在控制台的回溯日志中早些时候您的脚本中也有类似“'chromedriver' 可执行文件需要在 PATH 中”之类的内容，那么您应该能够做到：

from selenium import webdriver
driver = webdriver.Chrome("/path/to/chromedriver")

这应该告诉您的脚本在哪里可以找到 chromedriver。在 Mac 上，您通常可以使用：/usr/local/bin/chromedriver

【参考方案2】：

从https://sites.google.com/a/chromium.org/chromedriver/downloads下载chromium驱动

解压缩文件，然后从您的代码中编写如下内容：

     from selenium import webdriver 
     driver = webdriver.Chrome("/path/to/chromedriver")

其中 /path/to/chromedriver 是您的 chromedriver 的位置。

这是 Chrome Webdriver 的类声明：selenium.webdriver.chrome.webdriver.WebDriver(executable_path='chromedriver', ...

取自https://seleniumhq.github.io/selenium/docs/api/py/webdriver_chrome/selenium.webdriver.chrome.webdriver.html#module-selenium.webdriver.chrome.webdriver

【讨论】：

是的，但仍然使用该代码，出现相同的错误：webdriver/chrome/webdriver.py", line 62, in __init__ self.service.start() Exception AttributeError: "'Service' object has no attribute 'process'" in <bound method Service.__del__ of <selenium.webdriver.chrome.service.Service object at 0x7f05180ff5d0>> ignored
