我遇到了使用selenium进行测试的问题，我的测试无法连接到服务器“Connection refused”。我用circle.yml手动安装了Selenium及其chromedriver。我正在Symfony应用程序上运行Behat测试。
这是我的配置：
dependencies:
pre:
# Install Chrome driver
- curl http://chromedriver.storage.googleapis.com/2.23/chromedriver_linux64.zip | gzip -dc > chromedriver
- chmod +x chromedriver
# Install Selenium

我的测试是在带有Mink扩展（v2.2）和Mink Selenium驱动程序（v1.3）的Behat（v3）上运行。
此外，测试正在我自己的机器上传递。我在Windows上，所以我们无法比较，但至少我认为这不是我自己的测试代码失败。
我已经没想完了。它应该工作非常简单，但我不能使它工作。到目前为止，互联网对此毫无帮助。
感谢您的任何见解！

好的，我发现了这些问题：
java -jar selenium-server-standalone.jar -Dwebdriver.chrome.driver=chromedriver必须变为java -Dwebdriver.chrome.driver=chromedriver -jar selenium-server-standalone.jar
