is there any established best practices for QA/Testing process in ACS? looking to test below scenarios:- initial data coming from external file- initial data coming from DB- emails have personalizationany references would be helpful. thanks. 

I am looking for recommendation on how to version control ACS code, looking for what option are available, can we use GIT, if yes then how? any other options?

I want to check if a special character is there in a 'name' string or not, thought of using some regular contain function, but dont see any thing similar to that in ACS. any thoughts?
