摘要：Summary Cloud computing has actually been invented to be the latest computing standard that will work several distinctive research areas, such as software testing. Testing cloud applications will keep its unique characteristics that involve more recent testing techniques. Software testing helps to reduce the need for hardware and software services and also provide adaptable and valuable cloud platform. Testing within the cloud platform is easily manageable based on new test models and criteria. Prioritization approach is made responsive to build much better relationship between test cases. These test cases are clustered dependent on priority level. The resources can be used properly by applying load balancing algorithm. Cloud guarantees maximum usage of existing resources. But, security defined as a primary problem in cloud. At the present time, organizations are progressively moving excited about deploying and making use of ready-prepared business applications, with particular short-term to the marketplace. The possible lack of capital budgets for software planning and on principle deployments, along with the swift progression of cloud these are the reasons why one should make the interest on business application. However, these are the interests that help make the SaaS based business application on-demand. In this paper different approaches has been discussed that will help to extend the cloud environment. Also, the study of several well-known software testing approaches.
