Passing command line arguments to phantomjs.exe

[Ron Inbar]

Hi,

I just found out that in Selenium 2.31.0 there is built-in support for PhantomJS/GhostDriver, using the system property phantomjs.binary.path.

Is there a similar property that allows Selenium to pass additional command-line arguments to PhantomJS?

Thanks,

Ron

You can pass it by adding desired capabilities

Example: I don't know whats the exact command line param for disabling loading of images but same name should be used here too

PhantomJSOptions pjsO = new PhantomJSOptions();

                    pjsO.AddAdditionalCapability("phantomjs.page.settings.userAgent", " Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Trident/5.0)");

                    pjsO.AddAdditionalCapability("phantomjs.page.settings.userName", "xyz\\abcd");

                    pjsO.AddAdditionalCapability("phantomjs.page.settings.password", "fdfdsfsf");

                    pjsO.AddAdditionalCapability("ignore-ssl-errors", true);

                    pjsO.AddAdditionalCapability("proxy", "10.19.170.175:8080");

What you're suggesting doesn't seem to work through the wire protocol (which I have to use, since my code is in PHP). As you can see in the following transcript, the Desired Capabilities included "ignore-ssl-errors" but the Negotiated Capabilities don't include such a capability, probably because it's not recognized by GhostDriver.

Next, I'm going to try launching phantomjs independently with the required command line arguments and attaching it to a Selenium Grid hub using --webdriver-selenium-grid-hub.

I set up a Selenium grid hub on port 4444 and then launched phantomjs using this command line:
phantomjs --webdriver --webdriver-selenium-grid-hub=http://localhost:4444 --load-images=false

Although this method is a bit cumbersome, it seems to do the trick.
