Research Issues and Software Testing Methodologies and Mechanisms for Better Performance using Cloud Testing

Cloud Computing is an on-demand internet based virtualized system which is one of the most fast-growing information technology based mechanism that is adopted by software industry all over the world. Software Testing is the process of checkingfunctionality or activity that performed on cloud computing, it introduces features or capabilities of verification of software and reconstructed software for bug fix, Some-times new changes may impact on the existing functionality, this is also managed or identified by the testing methodologies. The main purpose is to give quality assurance about existing or recently introduced functionality or activity, so that it does not affect the existing functionality. The main objective of designing a new approach in software testing is to improve the quality of software after testing and after modifications that are done in the software, it also focuses on the side effects that are designed or progressed after modifications. We also discussed different testing methodologies that can be implemented on cloud computing for better performance along with the optimal Approximation Algorithm. The test bed simulation is done for experimental analysis, final results are given along with the graphical analysis. we also discussed on the future work and research issues that can be adopted for better performance of cloud computing and all the possibilities of mechanisms and methods that can be adopted or implemented using the software testing for bug fix.
