Hi all,

As I alluded to here, I have a set of modules that I'm writing, one of which I need to alter the default behavior of one of the modules due to lack of a database in the testing environment. I've tried using Test::MockObject and Test::MockModule, but to no avail. It seems that what I want to do is globaly replace one module with another, so that when something tries to use it and get objects from it, objects from the mocked module are returned instead. Is this at all possible? I'd be a lot happier if it were... Also, let me know if I need to be clearer in what I'm trying to do. If needed, I can come up with some pseudo-code that should demonstrate what I would like to happen.

Be your own disciple, fan the sparks of will
For all of us waiting, your kingdom will come

Update: Per request, here's the pseudo-code 
package Foo;
use DBI;

sub get_db_value
{
   # this sub requires database connectivity
}

Then, in other code: 
package Bar;
use Foo;

sub bar_func
{
   my $value = Foo::get_db_value();
   return $value * 42;
}

What I want to do is essentially replace get_db_value() with a subroutine that returns what I want it to return for testing conditions. That is to say, something like this: 
use Bar;

#something here to mock out Foo::get_db_value so that it returns a val
+ue of "2"
is(Bar::bar_func(), 84, "bar_func works as advertised");
