What is the role of CMMI Level in Testing?
Please understand that Testing is just part or subset of CMMI. Testing is addressed on a particular Process Area. If my memory serves me correct, it is the VER or Verification process area and sometimes addressed also in VAL or the Validation process area. It could also be the other way around. Each Process Area has its own level to be driven to the level 5. This is true for the Continuous Representation of CMMI version 1.1. I am not sure about the Staged Representaiton of the same version. Please refer to the website above for more details.
