Hi Ahmed,
The test case provided is JWebUnit code:
public void setUp() {
getTestContext().setBaseUrl("http://www.google.com";);
}
public void testSearch() throws Exception {
beginAt("/");
setTextField("q", "htmlunit");
submit("btnG");
clickLinkWithText("HtmlUnit");
assertTitleEquals("htmlunit - Welcome to HtmlUnit");
assertLinkPresentWithText("Get started");
}
but the HtmlUnit equivalent should be something like:
WebClient webClient = new WebClient();
HtmlPage page = webClient.getPage("http://www.google.com";);
page.<HtmlInput>getElementByName("q").setValueAttribute("htmlunit");
HtmlPage page2 = page.<HtmlInput>getElementByName("btnG").click();
List<HtmlAnchor> lnks = page2.getAnchors();
for (HtmlAnchor lnk : lnks) {
if (lnk.asText().indexOf("HtmlUnit") >= 0) {
lnk.click();
}
}
webClient.closeAllWindows();
Please note this is the latest stable release of HtmlUnit that is used.
Best regards,
Julien

Hello Julien,
Can we have a test case please? As the below gives 'StackOverflowError' with
SVN version (to be tackled soon).
WebClient webClient = new WebClient();
HtmlPage page = webClient.getPage("http://www.google.com";);
page.<HtmlInput>getElementByName("q").setValueAttribute("htmlunit");
HtmlPage page2 = page.<HtmlInput>getElementByName("btnG").click();;
webClient.closeAllWindows();
Yours,
Ahmed ----

Subject: [Htmlunit-user] NPE in HtmlUnit
Hi HtmlUnit team,
We have one user having this error using JWebUnit + HtmlUnit.
[junit] Testcase: testSearch(xyz.ExampleWebTestCase): Caused an ERROR
[junit] null
[junit] java.lang.NullPointerException

[junit] at
net.sourceforge.jwebunit.junit.WebTestCase.runBare(WebTestCase.java:79)
The test case simply consists in opening http://www.google.com and doing a
simple search. Then JWebUnit will automatically close the browser during the
tearDown. According to the stack, the NPE occurs when calling
WebTester.closeAllWindows().
Any idea of the cause of the issue? Is it possible that
SgmlPage.getDocumentElement() returns null?
Thanks,
Julien
