Error communicating with the remote browser. It may have died - RemoteWebDriver

[confusa]

Using the RemoteWebDriver client to connect to a remote server using
Firefox. Tests all run fine and work as expected. The tests have an
@AfterSuite tear down that runs the .quit() command which spits the
following trace into the TestNG logs:

I want to close out the session so that I don't have a lot of open
browser windows. What am I doing wrong here?

What version of Firefox?  If you were upgraded to 9, you'll need to upgrade your selenium to 2.16.1. Either way, upgrade and see if that resolves your issue.

Only yesterday I stumbled into this error and I was on 2.15.0. I had this. Bypassed by enclosing driver.quit() within a try catch and gobbling up the exception and doing nothing about it (an ugly way of sweeping the dust under carpet). Will try to come up with a short concise test to reproduce this issue in 2.16.1 and if i can get this reproduced will log an issue.

I was on firefox 8.0 if i remember correctly.

Firefox 9.0.1 and upgrading to 2.16.1 sadly did not resolve the
problem.

[Krishnan Mahadevan]

Perhaps you should create a small test against a public site that showcases this issue and log a bug on this.

[Mark Collin]

Can you show us your code, it looks like you are trying to call quite on an
object that has already been cleared.

Yeah, this is perhaps an issue with how the test is configured.
Running the tests using TestNG as a suite from the testng.xml. Each
test has an @AfterSuite that should run the .quit(). For some reason
it looks like that AfterSuite is getting called multiple times, not
sure why. For now I fixed it with this sort of tweak to the tear down:

if (remoteWebDriver().getSessionId() != null) {
remoteWebDriver().quit();

I am getting the same error, I also used driver.quit() method, instead of close. I am using 2.16.1 and FF 3.6.25 version. I used session id not null condition in tear down it did not work, any other works around please

[Mark Collin]

There was nothing to work round from what I can tell it was a coding error in the teardown.

 

Show us your code so we can see what you are doing.

if (!System.getProperty("keepBrowser", "false").equals("true")) {

if (driver != null) {

driver.quit();

}

}

Thanks Mark, I posted my code below. I think I will try the try catch logic as Krishnan mentioned. But that is not a correct way to do it
