[stringtemplate-interest] Unit test framework for StringTemplate

[Jose San Leandro]

Hi,

I'm making heavy use of StringTemplate in several projects, using a non-TDD 
developing methodology: change template, check template filling logic, build 
project, execute project, check template output.

It should be much better if I could, from a template
1) Generate a "TemplateFiller" interface, with all the getters that the 
template is expecting.
2) Generate a junit test that uses a "<TemplateFiller>UnitTestImpl" instance 
(which is the test itself) and compares the output of the template with the 
contents of a provided file.

Basically, I need a StringTemplate parser. I guess StringTemplate itself 
defines an ANTLR-based one I could use.

Do you think it would be possible to use it to extract all input parameters 
from a template? It would have to be recursive itself, and probably indicate 
at the end that the template input is an object graph, so I guess it will have 
to traverse the AST for a template.

I think a unit test framework for StringTemplate is highly desirable.

What do you think?
