Summary: Javascript and its navigator is null
Initial Comment:
Hello together,
I had a problem concerning a very small testapp written by me. It was derived
from a larger testframework developed by a colleague of mine. The Exception was
the same...
The simple HTML source with the javascript snipplet:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html;
charset=windows-1252"/>
<meta http-equiv="Content-Language" content="de"/>
<title> test </title>
</head>
<body>
<script type="text/javascript">
var nv = navigator;
var n = nv.userAgent.toLowerCase ();
alert(n);
</script>
</body>
</html>
The java source:
package test;
import net.sourceforge.jwebunit.junit.WebTestCase;
import net.sourceforge.jwebunit.junit.WebTester ;
public class Test_JavaScript extends WebTestCase {
private WebTester webTester;
private static String baseUrl = "url"; //replaced by me
private static String beginAt = "/startAt"; //replaced by me
public void setUp() throws Exception{
this.webTester = getTester();
}
public void testJavaScript() {
getTestContext().setBaseUrl(baseUrl);
getTestContext().addRequestHeader("Accept-Language", "de,de;q=0.7");
getTestContext().addRequestHeader("User-Agent", "Mozilla/5.0 (Windows;
U; Windows NT 5.1; de; rv: 1.8.1.3) Gecko/20070309 Firefox/2.0.0.3");
beginAt(beginAt);
}
public void tearDown() {
closeBrowser();
}
}
and here the Exception by the eclipse junit testrunner:
.log4j:WARN No appenders could be found for logger
(com.gargoylesoftware.htmlunit.WebClient).
log4j:WARN Please initialize the log4j system properly.

I thought that this is a htmlunit issue
(https://sourceforge.net/tracker/?func=detail&atid=448266&aid=2371881&group_id=47038)
but I'm happy to see that this already has been fixed.

A quick fix is to use getTestContext().setUserAgent()
