code Prioritization for testing promises to achieve the maximum testing coverage with the least cost. This paper presents an innovative method to provide hints on which part of code should be tested first to achieve best code coverage. This method claims two major contributions. First it takes into account a "global view" of the execution of a program being tested, by considering the impact of calling relationship among method/functions of complex software. It then relaxes the "guaranteed" condition of traditional dominator analysis to be "at least" relationship among dominating nodes, which makes dominator calculation much simpler without losing its accuracy. It also then expands this modified dominator analysis to include global impact of code coverage, i.e. the coverage of the entire software other than just the current function. We implemented two versions of code prioritization methods, one based on original dominator analysis and the other on relaxed dominator analysis with global view. Our comparison study shows that the latter is consistently better in terms of identifying code for testing to increase code coverage.

code coverage information is widely used to address problems in software development and maintenance phase. Researchers have developed different approaches and tools using code coverage concept to accomplish regression testing tasks. These tools did not provide runtime enhancement techniques. In this research, an implementation of a proposed tool is conducted to measure the code coverage percentage which will be known as phase 1. Phase 2 focuses on enhancing the code coverage keeping the performance degradation as minimum as possible. A suite of selective case studies was tested to calculate the percentage of statement coverage, the number of executed statements and the overall runtime. The design of the proposed tool in this research is based on computing the overall runtime as a single thread approach. When it was tested on multiple threads a race condition problem was discovered as all the threads where trying to access the files in the same time which might lead to a deadlock. This implies resources wasting and delaying overall runtime. So the calculation of the overall runtime is assigned to a single highly configured processor to avoid transition time between multiple processors. This enhances the regression testing performance while decreasing the overall cost of the regression testing process. The proposed tool enhancement results are compared to its relative results in case of no enhancement process to judge the robustness of the proposed approach for this research. The comparison shows a range of enhancement fluctuation between 49%-67% for different sized test cases.

The limitation of traditional testing tools makes it difficult to test the software of embedded system-the resource insufficiency of the embedded system as well as the strict requirement of real-time all contribute to the unavailability of the normal method for software testing. This document introduced a method about testing of embedded software, which based on code coverage and variable watching by using the software of Testbed and RTInsight. By using this method, it's effective to validate the software testing of embedded system.

Unit testing is a part of the process of developing software. In unit testing, developers verify that programs properly work as developers intend. Creating a test suite for a unit test is very time-consuming. For this reason, research is being conducted to generate a test suite for unit testing automatically, and before now, some test generation tools have been released. However, test generation tools may not be able to generate a test suite that fully covers a test target. In our research, we investigate the causes of this problem by focusing on structures of test targets to improve test generation tools. As a result, we found four patterns as the causes of this problem and proposed subsequent research directions for each pattern to solve this problem.

A novel approach for code coverage testing using hybrid metaheuristic algorithm

Testing is essential for the software’s success, but despite this, it is a time and resource-consuming activity. Therefore, researchers and practitioners continuously try to improve software testing automation to maximize test coverage and make it fast and reliable. Meta-heuristics are high-level frameworks that many researchers have used to generate test data for software testing. Maximizing test coverage would also indirectly help to find vulnerabilities in the code. In this paper, we have implemented an improved hybrid metaheuristic algorithm to generate test cases, utilizing particle swarm optimization (PSO) and genetic algorithm (GA) for path coverage testing criterion. The used fitness function is the combination of branch distance, approximation level and path distance. The proposed approach is a hybrid Particle Swarm Optimization and Genetic Algorithm (PSO-GA). We compared the meta-heuristics GA, PSO and Hybrid PSO-GA algorithm with different fitness functions. Moreover, the experimental result shows that the hybrid algorithm improves outcomes compared to GA and PSO for the combined fitness functions. This approach demonstrates noteworthy efficacy in addressing security vulnerabilities during testing, particularly due to its emphasis on comprehensive path testing. This methodology has yielded significant outcomes in the realm of security testing, highlighting its potential for practical application and exploration in research. Furthermore, more meta-heuristics can be incorporated into the hybrid approach. © Bharati Vidyapeeth's Institute of Computer Applications and Management 2024.

Traditionally, at the end of functional testing, testers resort to the numbers of problems reported and the test cases executed to evaluate the adequacy of the testing. This method generally results in that testers have no confidence in the test results. Therefore, we introduce coverage to settle this problem. EMMA is an open source testing tool which detects and reports Java code coverage. In this paper, two actual functional testing as examples to explain the processes of using EMMA command line and EMMA with Ant to obtain code coverage, further to explain how to increase test cases to accumulate code coverage based on EMMA. The final code coverage analysis reports testify that using EMMA can greatly ensure the integrity of the functional testing.

CP2K is a widely used application for atomistic simulation that can execute on a range of architectures. Consisting of more than one million lines of Fortran 95 code, the application is tested for correctness with a set of about 2,500 inputs using a dedicated regression testing environment. CP2K can be built with many compilers and executed on different serial and parallel platforms, thus making comprehensive testing even more challenging. This paper presents an effort to improve the existing testing process of CP2K in order to better support its continuing development. Enhancements have been made to the regression testing environment to support multi-platform testing and a new automated multi-platform testing system has been developed to check the code on a regular basis. Also, tools have been used to gain code coverage information for different test configurations. All the information is aggregated and displayed on the dedicated web page.

code coverage is successfully used to guide white box test design and evaluate the respective test completeness. However, simple overall coverage ratios are often not precise enough to effectively help when a (regression) test suite needs to be reassessed and evolved after software change. We present an approach for test suite assessment and improvement that utilizes code coverage information, but on a more detailed level and adds further evaluation aspects derived from the coverage. The main use of the method is to aid various test suite evolution situations such as removal, refactoring and extension of test cases as a result of code change or test suite efficiency enhancement. We define various metrics to express different properties of test suites beyond simple code coverage ratios, and present the assessment and improvement process as an iterative application of different improvement goals and more specific sub-activities. The method is demonstrated by applying it to improve the tests of one of our experimental systems. © 2015 IEEE.

code coverage is an important metric that is used by automated Android testing and security analysis tools to guide the exploration of applications and to assess efficacy. Yet, there are many different variants of this metric and there is no agreement within the Android community on which are the best to work with. In this paper, we report on our preliminary study using the state-of-the-art automated test design tool Sapienz. Our results suggest a viable hypothesis that combining different granularities of code coverage metrics can be beneficial for achieving better results in automated testing of Android applications.
