python - CircleCi 上的 WebDriverException selenium-python 测试

Question

我正在使用 selenium 和 pytest 设置 python 自动化测试，我的目标是在 Circleci 2.0 上运行它。

本地测试正常运行，但是CircleCi服务器出现这个错误，不知道为什么
我试图更新项目模块(但事实并非如此)

    def test_setup(self):
        options = webdriver.ChromeOptions()
        options.add_argument('-headless')
        self.driver = webdriver.Chrome(executable_path=ChromeDriverManager().install(), options=options)
        self.driver.maximize_window()
        self.driver.get(self.url)
        yield
        self.driver.quit()

我遇到以下错误:

venv/lib/python3.6/site-packages/selenium/webdriver/chrome/webdriver.py:73: in __init__
    self.service.start()
venv/lib/python3.6/site-packages/selenium/webdriver/common/service.py:98: in start
    self.assert_process_still_running()

self = <selenium.webdriver.chrome.service.Service object at 0x7f52e8a66a90>

    def assert_process_still_running(self):
        return_code = self.process.poll()
        if return_code is not None:
            raise WebDriverException(
                'Service %s unexpectedly exited. Status code was: %s'
>               % (self.path, return_code)
            )

Answer 1

案例结束，结果是 CircleCi 配置文件存在问题。为了运行这些测试，我被迫在 docker img 上安装 Chrome，方法是向 config.yml 文件添加适当的依赖项。
