Hi everyone,
I have a very simple page that contains a checkbox. On this, I put an
Event observer to catch all click events. When a simulate a click
with HtmlUnit, an exception is raised (the stack trace is at the end
of this message). I think it's a bug of prototype because this problem
only occurs when i create my webclient with the
BrowserVersion.FIREFOX_3, not with BrowserVersion.IE.
Any idea ???
Thanks in advance ;)
Here is my JSP :
----------------------------------------------- BEGINNING OF THE JSP
------------------------------------------------
<html>
<head>
<script type="text/javascript" src="/tutu/js/prototype.js"></
script>
<script type="text/javascript" language="javascript">
<!--
Event.observe(window, "load", function() {
Event.observe("chkAll", "click",
function(event) {
var element = event.element();
$$("input.chk").each(function(aCheck) {
aCheck.checked =
element.checked;
});
});
});
//-->
</script>
</head>
<body>
<input type="checkbox" id="chkAll"/> Select All
<input type="checkbox" id="chk1" class="chk"/> Value 1
<input type="checkbox" id="chk2" class="chk"/> Value 2
<input type="checkbox" id="chk3" class="chk"/> Value 3
</body>
</html>
---------------------------------------------------- END OF THE JSP
------------------------------------------------------
And the Junit test :
----------------------------------------------- BEGINNING OF THE TEST
------------------------------------------------
public class IndexTest extends TestCase {
public void testValidateFailure() throws Exception {
WebClient wc = new WebClient(BrowserVersion.FIREFOX_3);
HtmlPage page = (HtmlPage) wc.getPage("http://localhost:8080/tutu/
index.jsp");
HtmlCheckBoxInput selectAll = (HtmlCheckBoxInput)
page.getHtmlElementById("chkAll");
HtmlCheckBoxInput chk1 = (HtmlCheckBoxInput)
page.getHtmlElementById("chk1");
HtmlCheckBoxInput chk2 = (HtmlCheckBoxInput)
page.getHtmlElementById("chk2");
HtmlCheckBoxInput chk3 = (HtmlCheckBoxInput)
page.getHtmlElementById("chk3");
selectAll.click();
assertFalse(selectAll.isChecked());
assertFalse(chk1.isChecked());
assertFalse(chk2.isChecked());
assertFalse(chk3.isChecked());
}
}
---------------------------------------------------- END OF THE TEST
------------------------------------------------------
And, to finish, the stack trace :
