This chapter provides an overview of techniques for prioritization of requirements for software products. Prioritization is a crucial step towards making good decisions regarding product planning for single and multiple releases. Various aspects of functionality are considered, such as importance, risk, cost, etc. Prioritization decisions are made by stakeholders, including users, managers, dev...

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 ...

There exist a large number of approaches for prioritization of software requirements. Despite of several empirical studies, there is still a lack of evidence of which approaches that are to prefer, since different studies have resulted in different conclusions. Reasons may be due to differences in contexts, variables measured, and data sets used. This paper presents a research framework for stu...

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...

Abstract— The most appropriate prioritization method is still one of the unsettled issues of the Analytic Hierarchy Process, although many studies have been made and applied. Interestingly, many transportation evaluation and selection models using AHP apply only Saaty’s Eigenvector method. Many theoretical studies have found that this method may produce rank reversals and have proposed various ...

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...

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...

BACKGROUND Pakistan is one of only three countries where poliovirus circulation remains endemic. For the Pakistan Polio Eradication Program, identifying high risk districts is essential to target interventions and allocate limited resources. METHODS Using a hierarchical Bayesian framework we developed a spatial Poisson hurdle model to jointly model the probability of one or more paralytic pol...

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...
