Service Virtualization

While running DevTest 9.0 Selenium step for launching a Chrome browser, user who do not have Admin access on the machine will get a pop error message saying "Failed to load extension from {{location}}".

I found that its a Chrome issue for which it's advised to set a below property options.setExperimentalOption("useAutomationExtension", false);

But we are not sure how to set the same in DevTest 9.0. Can some one help on this is you have faced this issue.

Hi Raghu,

The chrome options which are defined as the command line arguments can be defined at the
             {
               "name": "chromeOptions",
               "value": "{'args': [],
                          'detach': false}",
               "type": "map"
            },
part of the selenium-config.json file which should be located in LISA_HOME.

If the '("useAutomationExtension", false);' for options.setExperimentalOption is equal to the argument "--disable-extensions", then this part may be
           {
               "name": "chromeOptions",
               "value": "{'args': ['--disable-extensions'],
                          'detach': false}",
               "type": "map"
            },
.

The '("useAutomationExtension", false);' for options.setExperimentalOption seems to work same as the argument "--disable-extensions".

However, if the '("useAutomationExtension", false);' for options.setExperimentalOption is not equal to the argument "--disable-extensions" or to set the argument "--disable-extensions" in selenium-config.json file does not have any changes, then please create a support case to ask the question like "The options.setExperimentalOption for chrome can be set or not to the Selenium integration in DevTest".

Thank you,

Thanks a lot for your suggestion Yusuke, instead of "--disable-extensions" i have used "-disable-extensions" in the selenium config file. And the script is working now.

Thanks again.

Hi Yusuke,

Thanks for this information. We had the same problem of a popup and it was resolved by adding above information. 

Is it possible for you to provide JSON structure for selenium-config to add Proxy information. 

I tried with below, but it is not working for some reason. 

{
"Version": 1,

"Description": "This file is used to define Selenium web driver info.",

"Web_Drivers": {

"Chrome": {
"Class_Name": "org.openqa.selenium.chrome.ChromeDriver",

"Capabilities": [
{
"name": "chromeOptions",
"value": "{'args': ['-disable-extensions'],
'detach': false}",
"type": "map"
},
{
"name": "proxy",
"value": "{'proxyType':'SYSTEM'}",
"type": "map"
},
{
"name": "acceptSslCerts",
"value": "true",
"type": "boolean"
}
]

}

}
}

Thanks,

Prakhar

Hi PRAKHAR,

By default, selenium-config,json does not include the definitions like:
{
 "name": "proxy",
 "value": "<default>",
 "type": "map"
 },
inside chrome definition.
Then I do not think your modification will reflect to the DevTest environment.

I did not check the chrome options which related proxy but if there is a argument related proxy for chrome, then maybe you can use this style:
{
 "Version": 1,

"Description": "This file is used to define Selenium web driver info.",

"Web_Drivers": {

"Chrome": {
 "Class_Name": "org.openqa.selenium.chrome.ChromeDriver",

"Capabilities": [
 {
 "name": "chromeOptions",
 "value": "{'args': ['-disable-extensions','-<proxy related argument>=<value>'],
 'detach': false}",
 "type": "map"
 },
 {
 "name": "acceptSslCerts",
 "value": "true",
 "type": "boolean"
}
 ]

}

}
}

If you find a argument which related proxy for chrome, then please try.

Thank you,
