CxxTest doesn't seem designed specifically to test template functions, 
although of course you could always do something like

        template<int Number>
        void template_test()
        {
            cout << "Testing " << Number << endl;
        }

        void test_template()
        {
            template_test<1>();
            template_test<2>();
        };

(Note that the template name itself cannot start with 'test', or CxxTest will 
try to run it directly - that might work if all the template parameters have 
default values, but that's probably not what you'd want anyways...)

I don't see a built-in way to pass command-line options to the tests, or only 
running one test in a suite.  I don't know if this helps at all, but if you 
use the CTest testing framework bundled with CMake, you can use the -R 
command line option to only run test executables whose name matches a given 
regular expression, so you could (for instance) prefix each of your test 
names with 'linux_' or 'windows_' or whatever and then run 'ctest -R linux' 
or 'ctest -R windows' depending on what platform you're on.
