[JW Lua] Unit-testing with jwlua scripts?

[dgr at leng.de]

Hi guys,

I am new to JWLua and Lua in general. (However I am not new to software development, 
see below.) I want to implement new features into Finale needed for classical guitar notation. 
I begged make music years ago to implement them. They told me liking my ideas but never 
implemented any of it. So I probably will have to go for myself because I am sick of the 
cumbersome and time-consuming editing due to lack of proper tools.

I have been educated with C (mostly embedded), have little experience in C++ and am 
coding in C# currently. I read the programming in lua book but still have trouble to understand 
some of the concepts. Therefore I assume I will have to ask a lot of questions on this channel 
and will appreciate anyone who answers. 

Today my first question: Is there any kind of unit testing framework or alike to use inside 
JWLua? I am getting used to test-driven-development and would like to do this here as well, 
if possible.

And second question: What is the best way to code object-oriented in JWLua?

Thank for your kind help in advance.
