Easily running subsets of tests is exactly what prompted me to start this 
discussion.  With my test_dirs hack to my subclassed builders, I accomplish 
this by making stubs off of a directory tree.  For example, if I have the following 
class heirarchy in my package:

    Foo::Bar
    Foo::Bar::One
    Foo::Bar::One::A
    Foo::Bar::One::B

Then tests for Foo::Bar::One::A live in t/Foo/Bar/One/A/t, 
tests for private methods of Foo::Bar::One live in t/Foo/Bar/One/t, 
and high-level tests for the entire distribution live in t/Foo/Bar.

If I want to test only the methods in the parent class Foo::Bar::One, 
I run "Build test test_dirs=t/Foo/Bar/One/t".   If I want to run 
the tests for that class and all it's children, I run 
"Build test test_dirs=t/Foo/Bar/One".  If I'm fixing a bug in Foo::Bar::One::B, 
I run "Build test test_dirs=t/Foo/Bar/One/B/t" over and over, and then when I'm 
satisfied I run a full regression test with "Build test".
