New issue 4918 by sand...@gmail.com: WebDriverBackedSelenium is
throwing 'no protocol' error on instantiation with webDriver 2.27.0
http://code.google.com/p/selenium/issues/detail?id=4918

We have automation project for our internal use and that used webDriver
2.25. We were using WebDriverBackedSelenium for some of the events. We
tried updating the selenium version to 2.27 with the firefox version to 16.
The setUp() creates the WebDriver instance and the WebDriverBackedSelenium
instance.

After the upgrade when we tried launching the test the setUp() started to
throw the error. While debugging we saw that creation of instance of
WebDriverBackedSelenium throws the error. We tried creating a small project
outside our framework and got the same error.

"Exception in thread "main" com.thoughtworks.selenium.SeleniumException: no

".

Our project uses a WebDriverBackedSelenium to simulate some of things. So
this error is stopping us to migrate to WebDriver 2.27 or 2.28(same issue).

Kindly look into the same.


Selenium version: 2.27 and/or 2.28
OS: Windows 7
Browser: Firefox
Browser version: 16 and/or 17.

Sample code :

WebDriver driver = new FirefoxDriver();
WebDriverBackedSelenium wdbsDriver = new WebDriverBackedSelenium(driver,"");

The second parameter (baseUrl) must be a valid URL, e.g.:

WebDriverBackedSelenium wdbsDriver = new
WebDriverBackedSelenium(driver,"http://localhost/");

The same code used to work for selenium 2.25. Thanks for your help.

The URL in the constructor can be any valid URL? What happens if that is
not a valid URL or points to a site that is down?

By "valid" I mean "syntactically correct". Versions prior to 2.26 did not
check this parameter, it was a bug, and it's fixed now.

This parameter (baseUrl) is used to open relative URLs. If it points to a
non-existing address, you still can open absolute URLs.

It is failing for me for a local file which I think would be a valid URL...
file:///root/devel/index.html will throw this error as well.
