I have 3 environments,

1. Dev 

2. Qa 

3. Stage

I created a class and some properties are inside that class and I included those properties in some rules like activity and section and Data transform in the Dev environment. Optimised few properties related the created class.

When I am moving my code from dev environment to QA environment, I forgot to add the class instace in the product. 

Because of this the code is not picking in qa environment. After some time I moved the class instace to qa. 

What will happen now, is my code works properly in qa or not, if my code is not working properly in qa? 

What will be the solution for this?
