Today I am opensourcing and introducing my Apex Data Generation library, which can be called as a framework or as builder as well.
More than year back, I was considering of introducing my Salesforce unit test framework, however, I didn’t open source that version. I have reconsidered it for usage outside of unit tests and renamed to DataGenerator and later I decided that it is worth to make it extendable so I refactored that class to DataBuilder, AbstractDataBuilder classes and moved auxiliary methods into Helper class. This is a new version, still this might not be perfect but I guess it might useful in many applications.
I am interested to get a feedback from you.
