Framework 2 : Test Library Architecture

               The test library architecture framework is very similar to the test script modularity framework and offers the same advantages, but it divides the application-under-test into procedures and functions (or objects and methods depending on the implementation language) instead of scripts.
             This framework requires the creation of library files (SQABasic libraries, APIs, DLLs, and such) that represent modules, sections, and functions of the application-under-test. These library files are then called directly from the test case script. 

            Much like script modularization this framework also yields a high degree of modularization and adds to the overall maintainability of the tests.
