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.

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