  • Publication number: 20150067648
    Abstract: Embodiments herein provide a method and system to create an optimized test suite for software testing. This system fetches required input parameters such as risk parameters, release type of the application, requirement details, test case details, requirement to test case relation and so on automatically using any suitable tool. Then, first level optimized test suite is formed by removing redundant and obsolete test cases from test case set. Further, probability of failure is calculated for each test case either manually or through automation and risk index value for each test case is defined. Further, test cases are classified based on value of risk index obtained. Further, second level optimized test suite is formed by using orthogonal array methodology. Furthermore, final optimized test suite with greater precision is prepared by considering execution time of iteration of all test cases along with their risk index values.

  • Publication number: 20140156654
    Abstract: The embodiments herein relate to web searches and, more particularly, to a gaze controlled approach to automate web search. The system identifies coordinates of the display unit the user is gazing at, at each instance of time and forms corresponding gaze vectors. Further, data displayed on the display unit is grouped into different semantic zones; with each semantic zone having different coordinates. By comparing coordinate information in the gaze vector and each of the semantic zones, the system identifies semantic zone the user is gazing at. Further, from the identified semantic zones, the system identifies a subject of interest for that user. A search is performed in the associated databases with the subject of interest as the key and the results are displayed to the user.
