I like your boss ... :-)

You must the first one I hear saying that JSP are easy to develop! ;-)

ok. What is your test client (i.e. the part that will read the header
and decide whether the test was successful or not)?

It looks like you are using the same kind of approach as Cactus is
using.

ok. I understand what you want to do. Note: you don't need HttpUnit
integration for just testing the header.

It will work but it means you're actually only using the client side
part of Cactus (i.e. only a small portion of it). Thus Cactus is only
providing you the bridge with the JUnit Test Runner. The Cactus
Redirector is actually more a handicap than a help for what you want to
do. The problem is that for each jsp test you'll have to write a
Cactus/JUnit testXXX() test, which is a pain I think. Of course, you
could write a generic testXXX() that will generically call each of your
JSPs but your tests will appear as only a single test for JUnit and it
will be a bit awkward.

It looks complex to me... :-) If you want to use Cactus I would drop
your JSPs and instead use Cactus ServletTestCase. Java classes can also
be reloaded by most containers so that shouldn't be an issue.

Not sure what you mean here by browser interaction.

This is Servlet/JSP API, not Cactus! Even though, it is documented in
Cactus... (see below).

Hum.. You said you read all the doc... Have you read this one:
http://jakarta.apache.org//cactus/howto_jsp.html which explains what you
can do with Cactus for testing JSPs!
