Re: Unit testing Tapestry 4.1 components with TestNG and Easymock
Thanks for you advice. I think I'm a bit further forward.
viewProductDetail is actually a Tapestry component and is instantiated
using the com.javaforge.tapestry.testng.TestBase; library.
I have removed the expect call from my testGetSaving method and moved
the replay/verify to my setUp method.
My main problem now relates to the following calls:
webRequest.getSession(true)
viewProductDetail.setRequest(webRequest)
The Mock WebRequest object gets passed ok with the second call, however
the as far as the viewProductDetail object is concerned the Session
doesn't exist and I'm not sure how to get access to it.
Any help will be much appreciated

Hmm .I can't pinpoint the exact problem but if it were up to me I
would
start out by changing things to look more like:
public void setUp() {
...
webRequest = createMock(WebRequest.class);
expect(webRequest.getSession(true)).andReturn(webSession);
...
}
public void testGetSaving(Product product) throws Exception{
viewProductDetail.setProduct(product); // this looks suspicious - if
it's a mock then what you are
// telling easymock is that it should expect someone to call
setProduct(product) when you invoke getSaving() ?
expect(viewProductDetail.getSaving()).andReturn(saving);
replay();
saving = viewProductDetail.getSaving();
verify();
assertEquals(saving, 0.02);
}

Hi,
Thanks for you quick reply.
Sorry, my fault, I must have deleted these while removing my sysouts for
this post.
I have tried using these but unfortunately receive the same exception. I
have also done several searches on google, which seems to suggest the
exception is caused by the omission of the replay() method. However
their inclusion doesn't seem to change anything.
My updated methods are:
public void setUp() {
...
webRequest = createMock(WebRequest.class);
expect(webRequest.getSession(true)).andReturn(webSession);
replay();
webSession = webRequest.getSession(true);
verify();
...
}
public void testGetSaving(Product product) {
try
{
viewProductDetail.setProduct(product);
expect(viewProductDetail.getSaving()).andReturn(saving);
replay();
saving = viewProductDetail.getSaving();
verify();
assertEquals(saving, 0.02);
}
catch(RuntimeException e){
System.out.println(e.toString());
}
Thanks for any help

I think getSession(boolean) also returns a value - so you'd have to
define
what that return value is with a statement like:
expect(webRequest.getSession(true)).andReturn(session); (or
andReturn(null)
) .

Hi All,
We have recently upgrading one of our apps to Tapestry 4.1 and I have
been asked to write some unit tests for the existing components.
I am new to Tapestry, TestNG and Easymock, so please bear with me.
I am trying to get the test to run through an if statement, but I
keep
getting the following runtime exception:
java.lang.IllegalStateException: missing behavior definition for the
preceeding method call getSession(true)
The class for the component is as follows:
public abstract class ViewProductDetail extends BaseComponent
{
@InjectObject(infrastructure:request)
public abstract WebRequest getRequest();
public abstract void setRequest(WebRequest webRequest);
@InjectState(visit)
public abstract Visit getSession();
public Double getSaving()
{
...
if(getRequest().getSession(false) != null)
{
Visit visit = getSession();
String discountcode = visit.getDiscountCode();
Double saving = new Double(rrp.getValue().doubleValue() -
price.getValue(discountcode).doubleValue());
return saving;
}
else
{
...
}
}
My Test class is as follows:
public class ViewProductDetailTest extends TestBase
{
...
@BeforeClass
public void setUp() {
viewProductDetail = newInstance(ViewProductDetail.class);
webRequest = createMock(WebRequest.class);
webRequest.getSession(true);
viewProductDetail.setRequest(webRequest);
}
@Test (dataProvider = CreateProduct)
public void testGetSaving(Product product) {
try
{
viewProductDetail.setProduct(product);
Double saving = viewProductDetail.getSaving();
assertEquals(saving, 0.02);
}
catch(RuntimeException e){
System.out.println(e.toString());
}
}
I'm not sure to the best way to create a session so that my if
statement
will be true. I'm trying to use webRequest.getSession(true), but it
doesnt seem to work and I don't know if there is a better way or if I
have missed
