So I want to run my tests in Chrome instead of Firefox (because Chrome offers mobile emulation capability) when using Selenium driver with Behat's Mink extension.

I'm running Selenium stand alone on a testing server, and running tests on a local machine.

So after running Behat tests, a Chrome session is created but is not used, instead, another parallel Firefox session also get created and gets used to run the test scenarios.

I tried that also in an environment with graphical display abilities, so a new Chrome window opens but only data;; is displayed in the address bar, then afterwards a Firefox window opens and tests are run there.

I'm running the latest version of Chrome (52.0.2743.82), Selenium standalone server (2.53.1 - Java version) and Chromedriver (2.22.397932)

My behat.yml contains the following:

default:
    extensions:
        Behat\MinkExtension:
            browser_name: chrome
            base_url: "<url to website>"
            default_session: selenium_chrome_session
            goutte: ~
            sessions:
                selenium_chrome_session:
                    selenium2:
                        browser: chrome
                        wd_host: "http://<testing server host>:4444/wd/hub"
                        capabilities:
                            extra_capabilities:
                                chromeOptions:
                                    args:
                                        - "--start-maximized"
                                        - "--test_type"

After looking at Selenium standalone server's logfile, I get the following output:

15:44:47.677 INFO [45] org.openqa.selenium.remote.server.DriverServlet - Executing: [new session: Capabilities [{chrome.switches=[--no-sandbox], browser=chrome, name=Behat feature suite, browserName=chrome, chrome.extensions=[], ignoreZoomSetting=false, chromeOptions={args=[--no-sandbox], extensions=[]}, version=, tags=[PHP 5.6.21-1~dotdeb+7.1]}]])

As you can see, Chrome session is successfully created, and then a new Firefox session is created afterwards and is used to conduct tests.

selenium 在firefox50版本上，关闭时提示Firefox已停止工作
