TL;DR

This paper proposes a strategy for designing and analyzing test cases specifically for recursive modules in program structures, aiming to reduce defect rates and corrective maintenance efforts. By applying structured test case design principles to recursive components, the approach improves test coverage and validation, leading to fewer defects in software systems using recursion.

ABSTRACT

Designing and analysis of test cases is a challenging tasks for tester roles especially those who are related to test the structure of program. Recently, Programmers are showing valuable trend towards the implementation of recursive modules in a program structure. In testing phase of software development life cycle, test cases help the tester to test the structure and flow of program. The implementation of well designed test cases for a program leads to reduce the defect rate and efforts needed for corrective maintenance. In this paper, author proposed a strategy to design and analyze the test cases for a program structure of recursive modules. This strategy will definitely leads to validation of program structure besides reducing the defect rate and corrective maintenance efforts.

Motivation & Objective

• To address the challenge of testing recursive modules in program structures, which are increasingly common in modern software.
• To reduce defect rates and corrective maintenance efforts in software development by improving test case design.
• To provide a systematic approach for designing and analyzing test cases tailored to recursive program components.
• To enhance the validation of program structure through targeted test case strategies for recursive functions.

Proposed method

• The authors propose a structured test case design strategy focused on recursive modules in program structures.
• The method emphasizes analyzing the recursive logic and control flow to derive comprehensive test cases.
• Test cases are designed to cover base cases, recursive cases, and edge conditions in recursive functions.
• The approach integrates static analysis of program structure to identify critical recursive components for testing.
• The strategy ensures that test cases validate both functional correctness and structural integrity of recursive modules.

Experimental results
