1 2 During regression testing, a modified system is often retested using an existing test suite. Since the size of the test suite 3 may be very large, testers are interested in detecting faults in the modified system as early as possible during this retesting 4 process. Test prioritization attempts to order tests for execution so that the chances of early detection of faults during retest5 ing ...

Regression testing is a time consuming, costly process of re-running existing test cases. As software evolves, the regression test suite grows in size. Test case prioritization techniques help by ordering test cases such that at least the test cases which cover the changes made in the software are executed amidst resource and time constraints. Genetic Algorithm (GA) has been widely used for tes...

A requirement may be defined as a demand or need. In software engineering, a requirement is a description of what a system should do. Requirements prioritization plays an important role in the requirement engineering process, particularly, with respect to critical tasks like requirements negotiation and software release planning. Selecting the right set of requirements for a product release lar...

This Software testing is “Performing Verification and Validation of the Software Product” for its correctness and accuracy of working. Every time it is not possible to perform each and every test case. Hence it is important to decide test cases prioritization. The aim of Test case prioritization is to prioritize the test case sequences and finding the faults as early as possible to improve prof...

Regression test case prioritization optimizes the ordering of test cases to be executed to meet some criteria like maximum code coverage or high rate of fault detection. In prior work we prioritized test cases according to a hybrid technique using variable based method that combined both selection and prioritization. We inferred in our approach that variables are vital source of changes in the ...

Test Case Prioritization (TCP) is setting priority to each and every test case from test case suit and executes those test cases in descending order. The proposed generic tool will first generate test cases from UML diagram sequence diagram and prioritize them on basis of following criteria's: prioritization on depending upon depth, prioritization on dependency of number of parameters, pri...

The testing of event driven software has significant role to improve overall quality of software. Due to event driven nature of GUI based software many test cases are generated and it is difficult to identify test cases whose fault revealing capability is high. To identify those test cases test suite prioritization is done. Various test suite prioritization methods exists for GUI based software...

When establishing lightpaths in an all-optical DWDM network, it is possible that concurrent lightpath requests will block one another if the lightpaths attempt to reserve the same wavelength on the same link. In this paper, we propose a novel signaling mechanism, referred to as label prioritization, which attempts to reduce the backward-link blocking in GMPLS-centric all-optical networks by ass...

Test case prioritization aims to schedule test cases in a certain order such that the effectiveness of regression testing can be improved. Prioritization using random sequence is a basic and simple technique, and normally acts as a benchmark to evaluate other prioritization techniques. Adaptive Random Sequence (ARS) makes use of extra information to improve the diversity of random sequence. Som...
