INTEGRATED SYSTEM TESTING
Integrated system testing is defined as the process by which all the scope in system components and parts are tested into full capacity and capability. The screening includes all the hardware, software, and other kinds of stuff, which include programs and new systems connected to it. The process is crucial to determine all the parts of the whole system up to efficiency, and it can be better to reveal faults of the methods to see capabilities. The first process starts with verifying the system’s components if they are compatible with the systems used, as it is crucial to make everything work well and better (Broy & Pretschner, 2017).
This helps in the validation of the whole parts to make the user’s preference crucial and better, as is what is needed. Then it comes to the role of software that is made through testing of the coexistence of the software with other systems. This is crucial as the software makes the system components run hardware capabilities of the whole hardware. The software and hardware interactions are the vital processes needed to run the systems for better efficiency and capabilities.
The following are the types of testing that are used. The first one is the big bang batch. This is done by taking all the components and the software where they are staked up together and tested, which is better when using the small system components. The second one is the top-down system approach, which is done by examining the system components from the highest level to the low level, which varies from the preferred method. The third one is the bottom-up testing approach. This is done by testing the low-level systems to the high-level systems, which are also preferable (Tahvili, 2018).
