Hi All,
I've started a new simple project using stripes and stripersist/hibernate.
As the basic development is finished I wanted to add some testing.
Folowing the example given in
http://www.stripesframework.org/display/stripes/Unit+Testing I've used
MockServletContext.
I want to test my UserActionBean. This class has simple handler method such as
list(), view(), cancel(), create(), edit(), save(), delete() and update();
I also have a getter and setter for the User entity.
The update() method handler is as simple as:
public Resolution update() {
getDao().save(getUser());
getDao().commit();
return new RedirectResolution(this.getClass(), "view").addParameter("user",
getUser());
}
The delete() method handler:
public Resolution delete() {
getDao().delete(getUser ());
getDao().commit();
return new RedirectResolution(this.getClass());
}
I've writen a test class UserActionBeanTest and all test run correctly (list,
view, create, save ...) but the update and delete one.
@Test
public void testDelete() throws Exception {
User user = createUser();
MockRoundtrip mockRoundtrip = new MockRoundtrip(getServletContext(),
UserActionBean.class);
mockRoundtrip.addParameter("user", String.valueOf(user.getId()));
mockRoundtrip.execute("delete");
String redirectUrl = (new
RedirectResolution(UserActionBean.class)).getUrl(Locale.getDefault());
verifyDestination(mockRoundtrip, redirectUrl);
}
@Test
public void testUpdate() throws Exception {
User user = createUser();
MockRoundtrip mockRoundtrip = new MockRoundtrip(getServletContext(),
UserActionBean.class);
mockRoundtrip.addParameter("user", String.valueOf(user.getId()));
mockRoundtrip.addParameter("user.name", "newName");
mockRoundtrip.execute("update");
RedirectResolution redirectResolution = new
RedirectResolution(UserActionBean.class, "view").addParameter("user", user);
String redirectUrl = redirectResolution.getUrl(Locale.getDefault());
verifyDestination(mockRoundtrip, redirectUrl);
assertUserUpdated(user);
}
When I run them I received some error message saying that the object user is
detached.

I really can't work out what's wrong and why the object is detached when using
MockServletContext.
If any one could help it would be much appreciated.
Don't hesitate to ask if you need more info.
Thanks.
Seb
