System and method are provided for facilitating performance testing. The method includes mapping application code for an application under test to at least one performance test script to generate a functionality mapping, the test script for executing functions in the application under test, receiving build release notes, determining at least one source code change from the build release notes, and receiving volume data from a production environment for the application under test. The method also includes using the build release notes and the functionality mapping to identify the source code changes for at least one functionality to be tested and for each functionality to be tested, analyzing corresponding volume data for a period of time, and using the volume data from the production environment to generate or update a workload model for the at least one functionality to provide a framework for subsequent performance testing of the application under test.
