Hello Kai,
Thanks for this very clear report. It's a nasty bug, and I will fix this ASAP.
For now, if you want a quick fix, just use
getTestContext().addUserAgent("Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:
1.8.1.3) Gecko/20070309 Firefox/2.0.0.3");
instead of a custom header.
Could you please open a bug on sourceforge to track the evolution.
In the futur, I will try to refactor plugins configuration, because it can't be
generic (for example, you can't change user agent with Selenium). Perhaps by
using property files.

Objet : [JWebUnit-users] Javascript and its navigator == null?
Hello together,
I just subscribed to the mailing list, my first one ever.
I've got 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 is 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.
