Question

I am using HtmlUnitDriver to open a link.
Here is my code:

HtmlUnitDriver webDriver = new HtmlUnitDriver();
webDriver.get("some url here");

But I am getting following exception.

Caused by: com.gargoylesoftware.htmlunit.ScriptException: Wrapped com.gargoylesoftware.htmlunit.ScriptException: Wrapped com.gargoylesoftware.htmlunit.ScriptException: TypeError: Cannot find function aa in object [object Object].

Answer 1

Exception says driver is facing problem with Javascript function while loading the page, By default HTMLUNITDriver disables Javascript.

You need to explicitly enable it and then try to navigate the URL
Try this and it should work.

HtmlUnitDriver driver = new HtmlUnitDriver(true);

True –> Here it mentions to enable Java script.

Moreover javascript engine used by HtmlUnitDriver is different from other browsers.Check this link for more details.
