Integration test planning

Integration test must be planned. Planning can begin when high-level design is complete so that the system architecture is defined.

Integration test planning

Integration test must be planned. Planning can begin when high-level design is complete so that the system architecture is defined. Other documents relevant to integration test planning are the requirements document, the user manual, and usage scenarios. These documents contain structure charts, state charts, data dictionaries, cross-reference tables, module interface descriptions, data flow descriptions, messages and event descriptions, all necessary to plan integration tests. The strategy for integration should be defined. For procedural-oriented system the order of integration of the units of the units should be defined. This depends on the strategy selected. Consider the fact that the testing objectives are to assemble components into subsystems and to demonstrate that the subsystem functions properly with the integration test cases. For object-oriented systems a working definition of a cluster or similar construct must be described, and relevant test cases must be specified. In addition, testing resources and schedules for integration should be included in the test plan.The plan includes the following items:

 

(i) clusters this cluster is dependent on;

(ii)  a natural language description of the functionality of the cluster to be tested;

 

(iii)list of classes in the cluster;

 

(iv)a set of cluster test cases.

As stated earlier in this section, one of the goals of integration test is to build working subsystems, and then combine these into the system as a whole. When planning for integration test the planner selects subsystems to build based upon the requirements and user needs. Very often subsystems selected for integration are prioritized. Those that represent key features, critical features, and/or user-oriented functions may be given the highest priority. Developers may want to show clients that certain key subsystems have been assembled and are minimally functional.
