Comparative Study of Test Prioritization Testing Technique

Testing of software is an important means of assessing the software to determine its quality. Testing activities support quality assurance by gathering information about the nature of the software being studied. Software testing has been proven that testing, analysis, and debugging costs usually consume over 50% of the costs associated with the development of large software systems. These activities consist of designing test cases, executing the software with those test cases, and examining the results pro 40~50% of development efforts, and consumes more effort for systems that require higher levels of reliability. So it is a significant part of the software engineering. studying these techniques a comparison will be made which shows the various their benefits and non-benefits in reducing the cost of the testing. case prioritization techniques. Earlier some studies have classified and organized existing test case prioritization techniques researched into four categories: (a) customer requirement techniques (c) cost effective-based techniques and (d) chronographic histor
