Hybrid regression testing technique: A multi layered approach
Varun Gupta, Durg Singh Chauhan · 2011
Software needs to be delivered well in time and within budgets. One way of doing this is performing incremental delivery of the software with each increment being adding new features along with changes requests. This incremental delivery is supported with requirement prioritization and needs to be tested for checking the reliability and quality. Testing of this increment calls for testing of not only of old newly added functionality but also of existing features so as to make sure that old parts that works perfectly well do not malfunctions after new code is added. Thus a new hybrid technique is proposed in this paper that clusters the test cases and prioritizes the clusters on basis of priorities of requirements represented by the clusters and series of selections and prioritizations at levels of test cases reduces the number of test cases to manageable level and execution of these test cases guarantees the testing of highest priority requirements associated with statements that are often associated with failures or has highest number of parents or sibling's statements dependent on it and is likely to be influenced by changes or failures in this statement.
