java - Why doesn't HtmlUnitDriver execute JavaScript?

Question

I got the following problem: I am running a JUnit testCase with Selenium 2.9 using HtmlUnitDriver with Browserversion Firefox_3_6. JavaScript is enabled. Now when it should call and execute the following javaScript function it does nothing:

function openIdsDocument()
{
    var windowBounds = getWindowBounds();
    var XMLHTTP = getAjaxRequestObject("XYZ.do?availableWidth="+windowBounds.width+"&availableHeight="+windowBounds.height, "", true);
    if (XMLHTTP != null)
    {
            XMLHTTP.onreadystatechange = function alertAJAXResponse()
            {
                    if (XMLHTTP.readyState == 4)
                    {
                            window.location.href = getContextPath() + "ABC.do";
                    }
            };
            XMLHTTP.send("timestamp=" + <%=System.currentTimeMillis()%>);
    }
    getLoadingState();
}

I want to get to ABC.do

If I execute my test with the FirefoxDriver it works.

Is there a way to get this working with HtmlUnitDriver? My test works if I manually call driver.get("http://host/ABC.do") but that cannot be the right way to do this.

Answer 1

You can enable JavaScript by doing either

• new HtmlUnitDriver(true);
• driver.setJavascriptEnabled(true);

What you need to do is to wait until the JavaScript is executed after get(url).

You can use Thread.sleep() method for adding some delay.

HtmlUnitDriver driver = new HtmlUnitDriver(BrowserVersion.FIREFOX_3_6);
driver.setJavascriptEnabled(true);
driver.get(url);

Thread.sleep(100);

runTest();

Update

As @Corey indicated in the comments, it could be nicer to use Explicit and Implicit Waits instead of Thread.sleep(). As I don't use them these days, I cannot confirm, though. It would be great if someone test them and update this answer.
