[Se2] [HtmlUnit] How to use WaitingRefreshHandler or ThreadedRefreshHandler?

[Felipe Knorr Kuhn]

Hello all,

I'm trying to use HtmlUnitDriver to open http://www.terra.com.br and got the following exception:

Exception in thread "main" org.openqa.selenium.WebDriverException: java.lang.RuntimeException: Refresh to http://www.terra.com.br/portal/ (180s) aborted by HtmlUnit: Attempted to refresh a page using an ImmediateRefreshHandler which could have caused an OutOfMemoryError Please use WaitingRefreshHandler or ThreadedRefreshHandler instead.

System info: os.name: 'Mac OS X', os.arch: 'x86_64', os.version: '10.6.4', java.version: '1.6.0_20'

After Googling up a bit, I noticed this is a common HtmlUnit behavior, but I couldn't find any pointers to change the refresh handler, especially when using WebDriver.

Thanks,

One way to make this change is to subclass the HtmlUnitDriver and
override the "modifyWebClient" method. The other way is to wait for
the (soon to be released) a6, which has this change already made.

Thank you, Simon.

I guess I'll just wait for a6 :)

I know that this is an old thread but I  want to post this as it might help others as I had the same problem.

Simon's advice worked for me. I got it to work by creating an annonymous class and overriding the modifyWebClient method.

This was my code:

HtmlUnitDriver driver = new HtmlUnitDriver() {

@Override

            protected WebClient modifyWebClient(WebClient client) { 

                client.setRefreshHandler(new ThreadedRefreshHandler());

return client; 

            } 

        };
