During the development stage of a large integration project we tend to focus more on the reusability factor which will extend our services to be used by the entire enterprise. The generic document handling/routing/mapping logic we write will will be used by various integrations implemented for various partners/applications belonging to different business segments.
This comes at a cost of having to do extensive regression testing(all the integrations) whenever we make any changes to the code.
We are trying to figure out a strategy/plan on how to do effective regression testing with limited effort.
Appreciate anyone’s help in this.
