Abstract

Middleware is currently used in all the customized software systems in order to felicitate the applications to majorly work on their functionality not on to much of process, memory management, load Analysis, counter, Timers, Database [DB], fault detection & correction and other such constraints which are very important in building the network machine software’s like what we use in 3G and 4G networks. (i.e. in IMS, IP Multimedia Subsystems). The Middleware of IMS will provide API’s [Application Program Interfaces] which will be used by the applications to perform their set of functionality. The middleware also provides platform for running 3rd party application software that support the functionality of the other applications on the upper layer of the stack. So this middleware APIs have to be checked for their functionality in the maintenance mode after every new feature addition, deletion or modification of the existing ones. So Regression Testing has to be done to validate the working of the APIs. Since these APIs are very important for application to work fine without any malfunctioning. This paper presents the variant of the testing technique which was followed previously in manual terms by replacing it with automated software tool set which reduces the time, error factor prior to every software release, making the network software application error free and work in a much effective manner.
