I have a set of Selenium WebDriver test that are failing randomly and I want to rerun only those test that fail immediately say try it for 3 times. I run the tests on grid with multiple browsers which I guess is causing the issue. I followed the solution given here in How to Re-run failed JUnit tests immediately? But whenever it tries to run a failed test we get this exception

Error Message

While my situation was slightly different I encountered the same error message. Are you using the WebDrive close() method in you code? I was able to fix the issue by using the WebDriver quit() method.

from the javadocs:http://selenium.googlecode.com/svn/trunk/docs/api/java/index.html

//Close the current window, quitting the browser if it's the last window currently open.

close()

//Quits this driver, closing every associated window.

quit()
