Depth first implementation allows a complete function to be implemented, tested and demonstrated. Can do depth first implementation of critical functions early. Bottom Up Integration. Use driver program to test. Driver program developed to test.
Cluster is tested.
Driver programs removed and clusters combined, moving upwards in program structure. Comments on Integration Testing In general, tend to use combination of top down and bottom up testing. Critical modules should be tested and integrated early. 2.3.4 Integration Test Documentation Test specification describes overall plan for integration of the software and the testing. Test case data Expected results for build n Actual test results References Appendices Scope of Testing provides a summary of the specific functional, performance and internal design characteristics which will be tested.
