org.openqa.selenium.NoSuchSessionException:无法在Docker容器中找到使用Behat/Mink和Selenium2Driver进行ID错误测试的会话 [英] org.openqa.selenium.NoSuchSessionException: Unable to find session with ID error testing with Behat/Mink and Selenium2Driver in docker container
问题描述
我正在尝试使用 Behat/Mink 和 Selenium2Driver ，这样我也可以测试Javascript功能.>
