A comprehensive review for test case prioritization in Software Engineering

In the past years, test case prioritization has been improved in the regression testing by the use of effective test cases. The continuous improvement and attention have increased in terms of prioritization algorithm, coverage criteria, measurement, application scenario and the practice concerned. It has focused mainly on Prioritizing and scheduling the test cases. The main purpose of this paper is to study the different prioritization techniques used by various authors in previous years. Regression testing, a type of testing in which is being used as a tool for checking, testing, and up-gradation of software. The test cases of all scheduling and prioritizing are set in the ordered and proper method and as result, this case shows the detection and a maximum number of faults in the software in which the technical faults are traced and detected as the detected faults. Through the fault detection of the test case, it reduces the test case and minimizes the execution cost. As a result, this method shows the running of the test case at a higher priority in order to reduce and minimize the cost, time and effort of software testing.
