how do I quit a web driver session after the code has finished executing?

Question

We're using Selenium's Python bindings at work. Occasionally I forget to put the call to WebDriver.quit() in a finally clause, or the tear down for a test. Something bad happens, an exception is thrown, and the session is abandoned and stuck as "in use" on the grid.

How can I quit those sessions and return them to being available for use without restarting the grid server?

Answer 1

While quitting in an ensure/finally block would be the safest option, configuring the idle timeout for your browser session would be a good safety release. See the section on timeouts in the Grid 2 wiki page:

Answer 2

You can restart the node instead of the server.
