Issue with Firefox driver when starting the webdriver

[Adrian Vraciu]

Hi guys,

I have the following issue. I have a suite of 22 tests. I start the suite, but after 8 tests ran, the rest of them are failing with the following error:

======================================================================

ERROR: testSecurity01 (CreateIPSEC.Create_IPSEC_GW_Term_Monthly.IpsecTest)

----------------------------------------------------------------------

Traceback (most recent call last):

    if _WaitForSingleObject(self._handle, 0) == _WAIT_OBJECT_0:

OSError: [WinError 6] The handle is invalid

Hi Adrian,

Can you please confirm what config u r using.

I will recommend that please use below setup that works for me.

1- Firefox version 37 or below

2- Selenium Webdriver jar 2.46

Never heared of the issue, so i can only guess:

Do you close (driver.quit) the driver after each Test-Method? 

[Adrian Vraciu]

At every test, at finish I use this method:

    def tearDown(self):

            self.driver.close()

I don't use driver.quit().

I would prefer driver.quit because if you ever want to run your tests on a grid-setup you will need to end the session to free the node for further test-execution.

You could try quit real quick and see if it makes a difference. I guess not, but it's worth a try.

This thread:
http://stackoverflow.com/questions/3028786/how-can-i-fix-error-6-the-handle-is-invalid-with-pyserial

Mentions a problem with 64bit python version.

Consider that. 

[Adrian Vraciu]

Yes, thanks for the hint. But I use python 3.4.
