[stringtemplate-interest] template testing

[Rafael Chaves]

Thanks, Udo, similar idea. Doesn't that force you to have a group file
per test case? I was hoping to make test cases more lightweight, so a
single template group could define dozens of them
(actual_foo/expected_foo, actual_bar/expected_bar, etc), ie, a
template group would define a test suite instead of a test case.

Cheers,

Rafael
