Test Prioritization or Test Case Prioritization

Testing a software or application is the most important phase of Software Development Life Cycle (SDLC). It plays a very essential role in deciding the quality and functionality of the software and ensures that the end product is as per client’s demand. The Testing of the software is done to detect faults and errors in its functionality, on the basis of which the performance and quality of the software is further improved. Test Prioritization is an extension of software testing, which is implemented to decide the priority of the test cases.

This priority of the test cases is decided through various factors that depend upon the need of the software, which are then assigned to the test cases for further processes. By prioritizing test cases, testers and developers are able to minimize the time and cost of software testing phase and make sure that the delivered product is of exceptional quality.
What is Test Prioritization?

The term “test prioritization” refers to the subjective and difficult part of testing that allows testers to manage risks, plan tests, consider cost value, and be analytical about which test to run in the context of the specific project. This process, is well known as Test Case Prioritization, which is a method of prioritizing and scheduling test cases. This techniques is used in order to run test cases of higher priority in order to minimize time, cost and efforts during software testing phase.

Furthermore, test case prioritization provides assistance with regression testing and improves its performance. Through this method, testers can easily run test cases, which have the highest priority and provide earlier defect faults. Also, an improved rate of fault detection during the testing phase, allows faster feedback of the system that is under test. With test case prioritization software engineers can get assistance in correcting faults earlier than might otherwise be possible. Moreover, to decide the priority of test cases, various factors depending upon the need of the software are decided.
