EMPIRICAL STUDY OF GUI TO REUSE UNUSABLE TEST CASES - Vol 75 - Issue 2 - Regression Testing Approach

Sep 11, 2026

Upgrade of web applications due to evolving user requirements often renders portions of the existing test suite unfeasible after modification of the application behavior. This study focuses on the impact of modified versions on prior test cases and addresses unfeasible outcomes by adjusting input constraint values. A regression testing strategy is applied to reuse unusable test cases, increasing the number of feasible tests in modified versions while improving efficiency and reducing regression testing cost.

In developing web applications the graphical user interface (GUI) plays vital role. Due to frequent changes in application it varies from old version and modified version. Finally, it makes some of the test cases as unfeasible in modified version. We mainly, focus in areas where modified version is affecting the old test suite to make some of the test cases as unfeasible. To rectify this problem, we used to make changes in input constraint values. Here, we consider regression testing to make testing more flexible whenever changes occurred. Testing can be done manually and also by using tools. By this technique we can make maximum number of unfeasible test cases to feasible in modified versions. By reusing the unusable test cases it requires less time to make modified version as more efficient and also reduces cost of regression testing. Keywords: Regression Testing, Feasible And Unfeasible Test Cases, Constraint Values, Web Applications. 1. INTRODUCTION To develop any software for desktop application the common approach is graphical user interface (GUI) . On web applications wide numbers of companies arerelayed due to more interactive to the users. Requirement of users changes frequently so it makes differences between versions. When varies occur it also make changes in source code. Due to this when testing occurs it forms some unfeasible test cases which cannot give expected output. In this regression testing for web applications developed a technique as making changes in input values. When the modification occurs it cannot reach the expected output. So, to make them useful in modified version we make changes in the constrain values. When the implementation has done, work of the testing will become complicated because of changes in source code testing has to be done frequently. So, we use regression testing which can repair and make unfeasible test cases as feasible test cases. Here, we mainly concentrate on parts where it affected due to modification. Then it can form test cases and verifies whether it can give actual output or not. This technique is used to reduce cost of regression testing by making to reuse maximum number of test cases. 2. PROBLEM FORMULATION It demonstrates a technique for testcases where code was affected and result faultsin test cases. The complete code is taken in PHP form. Their main goal is to concentrate on affected part and they select such paths by dividing whole program into sub parts. Finally, they will test these test cases with different input values [1] . They proposed steps to assure modifications done according to user requirements or not. It derived LQN models for software’s by designing UML diagrams. It is a step by step approach for converting software models as specifying UML diagrams. Finally, this is more useful for our approach to make defects to be corrected [2, 3] . It demonstrates a programming language works on server side to create web application dynamically with PHP. At the runtime many of errors are detected and these errors are declared as dangling references. I

FAQs

Why do test cases become unfeasible in modified web application versions?

Frequent changes in user requirements lead to differences between versions, including changes in source code, which can prevent test cases from reaching expected outputs in the modified version.

How does the proposed approach make unfeasible test cases feasible?

By changing input constraint values and applying regression testing so that test cases can be adapted to satisfy conditions in the modified version.

What are the benefits of reusing unusable test cases in regression testing?

Reusing adapted test cases reduces the time needed for modification, improves efficiency, and lowers the overall cost of regression testing.
