subject : SOFTWARE ARCHITECTURE, DESIGN AND TESTING
2. Components of a software system are most of the time developed independently. These components are brought together to do the integration testing. Integration testing can be done either using a bottom-up approach or a top-down approach. Consider the Figure 1: Component Diagram given below depicting the hierarchy of components in an arbitrary software system. Process 1 Process 2 Process 3 Process 4 Process 5 Process 6 Process 7 Figure 1: Component Diagram (a) If a bottom-up integration testing approach is implemented, list the sequence of tests required. (9 marks) b) What will be the sequence of tests incase the components are integrated following a topdown approach. (9 marks) (c) The creation of drivers and stubs is an overhead. Explain the approach that can be used to remove the need of drivers and stubs thus overcoming the overhead associated with them? (7 marks)Step by Step Solution
