functional test bases on funtional requirements. Funtional tests are different than integration tests. A functional integration test will focus on the functionality of a collection of interfacing modules, usually in terms of the partial or complete user workflows, use cases, operations, or features these modules provide.A functional system test will focus on the functionality of the application as a whole, complete user workflows, use cases, operations, and features. A functional system integration test will focus on end-to-end functionality that spans the entire set of integrated systems.
