Building a product involves determining the product behaviors due to the following unstated requirements:

• Inter-operability with other products in the ecosystem and their respective configurations
• Operational environments (specific configuration, networks, specific hardware models, etc) in which the products are deployed.
• Sequences of operations between the above

Assessing product behavior for these unstated requirements is often a big challenge as this result in test matrix explosion resulting in expanded test cycle. It is important for QA teams to quickly identify these requirements, add them to the test suite and automate them. While traditional black box approaches like equivalence partition and boundary value techniques help to cover a spectrum of problems, it has been a challenge to improve test coverage and help assess the unstated, implicit requirements mentioned above.

This paper presents the Test Architecture based solution to solve these problems. Test Architecture is a formal approach to arrive at Test Requirements and Test Design based on the stated and unstated product requirements and helps to evaluate the product behavior in a dynamically changing ecosystem.
