I read it this example in the documentation

If I understood wheel the documentation that will run 3 different tests with T1, T2 and T3 as the T of the test.

Maybe my previous problem is easier to explain if I break it in 2 different questions:

1. How can I pass more than one T to the test, in my case I need 3 Ts in the test which each has different values. 

A simpler scenario in this case would be trying to test this:
TEST{
T1 a;
T2 b;
BOOST_CHECK(a+b == b+a);
}
And suppose I want to run the test with 4 combinations of parameters:
T1=int, T2=float
T1=float, T2=int
T1=int, T2=int
T1=float, T2=float

2. The other problem is that one of the Ts in my example is  a "template<class, class> class” and I can’t find the way to make it even compile using that kind of type in the example from the documentation.
