Question

我正在使用Behat，Mink和Selenium2进行测试我正在运行示例search-with-autocompletion测试，该测试在场景中使用@javascript标记这是我得到的例外：

我使用docker-selenium和geckodriver v0.18运行Selenium2独立服务器v3.5.3。

我对Behat的配置：

default:
  context:
    class:  'FeatureContext'
  extensions:
    Behat\MinkExtension\Extension:
      base_url:  '<skipped>'
      goutte:
        guzzle_parameters:
               curl.options:
                  CURLOPT_SSL_VERIFYPEER: false
                  CURLOPT_CERTINFO: false
                  CURLOPT_TIMEOUT: 120
               ssl.certificate_authority: false
      selenium2:
        wd_host: "http://127.0.0.1:4444/wd/hub"
        capabilities:
            browser: firefox
#            acceptSslCerts: true
#            marionette: true

# No context:
no_context:
  paths:
    bootstrap: 'NON_EXISTING_FOLDER'
  filters:
    tags:      '~@javascript'

# Context based on inheritance:
inheritance:
  context:
    class:      'InheritedFeatureContext'

# Context based on traits:
traits:
  paths:
    bootstrap:  'features/php54_bootstrap'
  context:
    class:      'TraitedFeatureContext'

# Context based on subcontexting:
subcontexts:
  context:
    class:      'SubcontextedFeatureContext'

如果连接到localhost:4444，我可以手动创建会话如果使用python-selenium，我可以运行此代码：

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

driver = webdriver.Remote(
           command_executor='http://127.0.0.1:4444/wd/hub',
              desired_capabilities=DesiredCapabilities.FIREFOX
        )

#driver = webdriver.Firefox()
driver.get("http://www.python.org")
assert "Python" in driver.title
elem = driver.find_element_by_name("q")
elem.clear()
elem.send_keys("pycon")
elem.send_keys(Keys.RETURN)
assert "No results found." not in driver.page_source
driver.close()

先谢谢大家。

硒2和硒3不相同。它们不是100％兼容。硒3是朝向硒的W3C标准迈出的一步。

从例外情况来看，Mink似乎与Selenium 3不兼容。所以要么将你的Python selenium版本降级为2（这也可能不起作用，因为最新的浏览器可能只支持3个）
