selenium remote driver

If you're running your tests against a Selenium-WebDriver grid instance or using a service like Saucelabs, then you need to include the selenium-remote-driver JAR file in your project's dependencies in addition to the default selenium-java. As of this writing, the selenium-chrome-driver JAR has a dependency on selenium-remote-driver so in theory you shouldn't need to add it explicitly for these use-cases, but it's a good idea to mark your direct dependencies explicitly.
