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 instead of scripts. This framework requires the creation of library files which has reusable code represented in modules, sections and functions of the application-under-test. These library files are then called directly from the test case script.
Advantages:
§ Performance of automation scripts increases due to higher code re-usability
§ Functionality changes can be accommodated easily by updating only the specific "Business Function" script
§ Object recognition changes can be easily accommodated in tools without inbuilt object repository
Disadvantages:
§ Technical expertise is necessary to write Scripts using Test Library Framework
§ More time is needed to plan and prepare test scripts
§ Cannot drive the data from database
