2. Questions about Software Regression Testing (30\%) Figure 2 shows the class relation structure among the classes of a program, where "I" indicates an Inheritance relation between two classes. "AG" represents an aggregation relation between two class objects, "AS" indicates an association relation between two classes. - (10%) Please identify the class test order for the class diagram in Figure 2. - (10%) What is the firewall(s) for Class 7 and Class 6 when change both of them. Please mark them in Figure 2 respectively. - (10%) Identify the class re-test order based on your identified firewall and class re-test order for class C6 when you change it only. Figure 2.
