Although we already covered this page in listing 15.7, let's review it briefly. In our
JSP
,
we use the RichFaces and Ajax4jsf tag libraries to implement the desired Ajax behavior.
We start by defining two
rich:panel
components
B
and
E
to hold the rest of our
components. In the first panel, we put a
commandButton
to submit the form to the bean
specified in the
action
parameter
C
. The command button also submits a
status
parameter to the bean
D
. Notice the
reRender
parameter of the
commandButton
. This
attribute specifies an
ID
of another component that needs to be rerendered. In our
case, we specify an
outputText
F
. You can see the screen for this
JSP
in figure 15.2.
Now let's implement some tests for this Ajax scenario.
JSFU
nit relies heavily on the
HtmlUnit headless browser. You can use the
JSFClientSession
and click anything,
regardless of the fact that the request to the bean will be submitted via JavaScript. The
code for these tests is shown in listing 15.12.

Testing the Ajax components from the album_details.jsp
[...]
public class
TestPurchaseAlbum
extends
ServletTestCase {
public static
Test suite() {
return new
TestSuite( TestPurchaseAlbum.class );
}
public void
testCommandButton()
throws
IOException, SAXException {
JSFSession jsfSession =
new
JSFSession( "/album_details.jsp" );
B
C
D
JSFServerSession server = jsfSession.getJSFServerSession();
JSFClientSession client = jsfSession.getJSFClientSession();
E
client.click( "PurchaseButton" );
Object userBeanValue = server.getManagedBeanValue(
"#{albumDetailsBean.status}");
F

H
assertEquals( "Successfully purchased: ", userBeanValue );
String spanContent =((HtmlPage) client.getContentPage())
.getElementsByTagName( "span" ).item( 0 ).getTextContent();
assertEquals(spanContent, "Successfully purchased:");
}
}
As usual, we start the implementation by declaring a test case by extending the
Servlet-
TestCase
B
. In the test method
C
we obtain a
JSFServerSession
object and extract
the
JSFServerSession/JSFClientSession
D
. Then we click the
"PurchaseButton"
