Defining software test architectures with the UML testing profile

The concept of software test architecture (STA) has been discussed within industry meetings with little universal agreement on its usage. This paper proposes the use of Test Architecture (TA) as defined in the OMG UTP in place of STA and refines some earlier paper definitions and usage of STA to align with UTP and ISO concepts. Further, the paper considers TA styles of test environments and how they can use UTP modeling, which can lead to test automation as well as to better testing outcomes.
