def open(self,url):
self.do_command("<STR_LIT>", [url,])<EOL>
Opens an URL in the test frame. This accepts both relative and absolute
URLs.

The "open" command waits for the page to load before proceeding,
ie. the "AndWait" suffix is implicit.

\ *Note*: The URL must be on the same domain as the runner HTML
due to security restrictions in the browser (Same Origin Policy). If you
need to open an URL on another domain, use the Selenium Server to start a
new browser session on that domain.

'url' is the URL to open; may be relative or absolute
