Cloud computing has emerged as a new computing paradigm that impacts several different research fields, including software testing. In cloud computing, the user can use high end services in form of software that resides on different server and can be accessed from all over the world. It not only changes the way of obtaining computing resources but also alters the way of managing and delivering computing services, technologies and solutions. Software testing reduces the need for hardware and software resources and offers a flexible and efficient cloud platform. Testing in the cloud platform is effectively supported by engineers based on new test models and criteria.
