Command line server for the IE driver has stopped working (upgrading to 3.6 from 3.4) using Open Browser. it works using Create Webdriver

[andreabisello]

Initially i opened the bug report on SeleniumHQ because i thought the crash was related to the driver, but now i moved here becase i think the crash is related to seleniumlibrary.

You can take a look at this bug report https://github.com/SeleniumHQ/selenium/issues/4901 for the screenshot and all software version, anyway with this test case

*** Settings ***
Library                  SeleniumLibrary     15    15

*** Test Cases ***
CrashTest
    Open Browser            https://www.google.com              ie

you obtain a crash, but splitting Open Browser in Create Webdriver and then Go To, it works

CrashTest
        Create Webdriver                Ie
    Go To                           https://www.google.com

Could you provide more details?

• What did you actually upgraded?
• What was the used IE, IEDriver, Selenium and SeleniumLibrary versions?
• What Windows version you are using?
• Would you have an stack trace from the log file available?

[andreabisello]

system :

OS: Microsoft Windows 10 Pro 10.0.15063 build 15063 Selenium Version: robotframework (3.0.2) robotframework-ftplibrary (1.4) robotframework-requests (0.4.7) robotframework-selenium2library (1.8.0) robotframework-seleniumlibrary (3.0.0b1) robotframework-SikuliLibrary (0.1.5)

i'm using this

instead of this

i changed Open Browser with Create Webdriver to obtain Ie log like descripted here and making this i understand that with Create Webdriver it works.

how i can take logs using Open Browser?

[aaltat]

I was interested to see the stack trace on the log.html. One can see it when using --loglevel trace option from command line. Also what is the Selenium version you are using?

[andreabisello]

@aaltat sure. Selenium (3.6.0) I attached the log in the zip file with the test.robot file log.zip .

I cannot open that zip on mobile. Could you copy the error and traceback here? Could you also translate errors to English?

[andreabisello]

@pekkaklarck sure.

i put here https://codepen.io/anon/pen/QqYJgz/ log.html to be readable

This error message "error: [Errno 10054] Connessione in corso interrotta forzatamente dall'host remoto" means " Running Connection closed by the remote host".

i tried to

• run as administrator
• shutdown windows firewall

[aaltat]

Thank you from the input. I can reproduce the problem, but I think it is a Selenium problem. I will write pure selenium implementation and attach it to the Selenium issue.

[aaltat]

It is a Selenium or an IEDriverServer.exe problem, with IEDriverServer.exe 3.5.0 and 3.6.0 this does not work:

from selenium import webdriver

driver = webdriver.Ie()
driver.set_script_timeout(5.0)
driver.get('https://www.google.fi')
driver.quit()

But same code works with IEDriverServer.exe 3.4.0 it works fine. I will raise an issue the Selenium issue tracker and close this one.

[aaltat]

Commented to the https://github.com/SeleniumHQ/selenium/issues/4901 issue that this looks like a Selenium or IEDriverServer.exe problem. Asked them to reopen the issue and lets follow what happens. But in any case, it is for Selenium maintainers to fix the problem.

[pekkaklarck]

This is clearly an issue in the IEDriverServer.exe. Does it have its own issue tracker?

[aaltat]

The difference, which causes the issue that Open Browser keyword calls the set_script_timeout() method by default. And calling this method causes the problem. The Create Webdriver does not call set_script_timeout() method and therefore the error does not happen.

@pekkaklarck as far I recall Selenium also makes the IE driver (Edge driver is made by Microsoft) and I do not know where that source code lives. But I guess they will point me to the right issue tracker, if it is the wrong one.

[pekkaklarck]

Isn't it kind of a bug that Create Webdriver doesn't call set_scriot_timeout?

[aaltat]

Well, good question. I do not have good opinion on the matter because the I do not use the keyword.

[kamlesh-c]

I am facing same issue My IE version : 11.371.16299.0 Robot Framework 3.0.2 (Python 2.7.13 on win32) IE Driver version : 3.9.0.0 is any workaround for this issue

[aaltat]

Because this is quite old issue and your version are different, then most likely you don't have a same issue.

Could you open a new issue and provide the following details?

• What was the used IE, IEDriver, Selenium and SeleniumLibrary versions?
• What Windows version you are using?
• Would you have an stack trace from the log file available?
