Table 1

Notation used.

Notation	Description
CD	Class Diagram
𝐶	Set of classes of the original program
𝐶^′	Set of classes in the modified program
CIG	C# Interclass Graph
𝑀1	Set of directly changed methods
𝑀2	Set of deleted methods of the program
𝑀3	Set of methods that explicitly call the changed, and deleted methods
𝑀	={𝑀1+𝑀2+𝑀3}
AC	Class that contain a changed or deleted method
ACD	Affected Class Diagram that contains classes affected by modification in source code.
𝑇	Test cases saved in the initial development of the program
𝐴𝑇	Test-method coverage table for the methods and their corresponding test cases
𝑇𝑖	Test case that covers method 𝑚𝑖
𝑇^′	Set of test cases from the test suite that needs to be retested that cover classes in ACD
𝑇^′′	Set of test cases that traverse the affected or potentially affected edges ED
ED	Set of affected or potentially affected edges that reach modified code
𝑇^′′′	Reduced test cases from 𝑇^′′
TF	Trace file generated by the C#.net program
