1. A regression testing selection method for a framework-based application having programming applications with both language program files and configuration files, said method comprising: abstracting a frame configuration model instance by analyzing configuration files prior to any modifications made to the program; said frame configuration model instance denoting individual configuration nodes in said framework model and further defining relationship between one or more code units in said configuration nodes and program code units in said application; constructing one or more control flow test cases by profiling select test cases of said application, wherein said control flow consists of code units traversed during test case execution and control flow of said code units; and obtaining an extended control flow by correlating configuration nodes in said framework configuration model instance with said code units in said control flow.
