The software integration testing process of airborne TCAS Traffic Alertt and Collision Avoidance System) is designed.
The phases used and analyzed based on Waterfall model are the Requirements specification, Design, Construction (implementation or coding), Integration, Testing and debugging (validation), Installation and Maintenance (Table 2).
We augmented the integration of units considering deeper interaction chains (up to the deepest level), without making the integration testing activity too expensive, since we integrate units in a configurable level of integration depth.
Neves et al. [46] developed an approach for integration testing of OO and AO programs in which a unit is integrated with all the units that interact with it in a single level of integration depth.
The cost is in integration testing of the components.
Additionally, integration testing is needed as components are assembled to make business application systems.
The increasing complexity and tight coupling of real-time subsystems make integration testing unmanageable.
System integration testing is carried out wherein functional and performance requirements of the system are monitored.
An automatic integration testing environment is still being prepared and not yet in standard use.
Following the successful first year, this $2.55 million award will focus on system integration, testing and evaluation.
We exemplify its use in the formalisation of a selection criterion based on coverage of process communications for integration testing.
