  • Studying the Feasibility and Importance of Software Testing: an Analysis
    Dr. S.S.Riaz Ahamed / Internatinal Journal of Engineering Science and Technology Vol.1(3), 2009, 119-128 STUDYING THE FEASIBILITY AND IMPORTANCE OF SOFTWARE TESTING: AN ANALYSIS Dr.S.S.Riaz Ahamed Principal, Sathak Institute of Technology, Ramanathapuram,India. Email:[email protected], [email protected] ABSTRACT Software testing is a critical element of software quality assurance and represents the ultimate review of specification, design and coding. Software testing is the process of testing the functionality and correctness of software by running it. Software testing is usually performed for one of two reasons: defect detection, and reliability estimation. The problem of applying software testing to defect detection is that software can only suggest the presence of flaws, not their absence (unless the testing is exhaustive). The problem of applying software testing to reliability estimation is that the input distribution used for selecting test cases may be flawed. The key to software testing is trying to find the modes of failure - something that requires exhaustively testing the code on all possible inputs. Software Testing, depending on the testing method employed, can be implemented at any time in the development process. Keywords: verification and validation (V & V) 1 INTRODUCTION Testing is a set of activities that could be planned ahead and conducted systematically. The main objective of testing is to find an error by executing a program. The objective of testing is to check whether the designed software meets the customer specification. The Testing should fulfill the following criteria: ¾ Test should begin at the module level and work “outward” toward the integration of the entire computer based system.

Additionally, to evaluate the characteristic of a product. The testing process evaluates the quality of the software. You know what testing does. No need to explain further. But, are you aware of types of testing. It’s indeed a sea. But before we get to the types, let’s have a look at the standards that needs to be maintained. Standards of Testing The entire test should meet the user prerequisites. Exhaustive testing isn’t conceivable. As we require the ideal quantity of testing in view of the risk evaluation of the application. The entire test to be directed ought to be arranged before executing it. It follows 80/20 rule which expresses that 80% of defects originates from 20% of program parts. Start testing with little parts and extend it to broad components. Software testers know about the different sorts of Software Testing. In this article, we have incorporated majorly all types of software testing which testers, developers, and QA reams more often use in their everyday testing life. Let’s understand them!!! Black box Testing The black box testing is a category of strategy that disregards the interior component of the framework and spotlights on the output created against any input and performance of the system.

    TESTING GUIDE Automated Testing for SuccessFactors Introduction This guide will give you an overview of the different aspects of testing your SuccessFactors environment. As most employees interact in some way or form with the system, it’s crucial to test your system regularly and around crucial events to make sure you provide an excellent employee experience. The following topics will be explored: • Testing During An Implementation • Testing For Configuration Changes • Testing For Quarterly Releases • Manual vs. Automated Testing © 2019 Page | 2 Automated Testing For SuccessFactors Testing During An Implementation During an implementation, testing is critical to make sure the system is designed and configured according to expectations. One of the most known test is User Acceptance Testing (UAT) in which a client signs off that the system works as expected. Before UAT, there are many different tests you would like to perform. These tests are done during different phases of a project. Some only once, others multiple times. Let’s start with looking at what phases there are during a SuccessFactors implementation. This may differ slightly, but all SuccessFactors implementations basically follow the same path. The reason for this is that the Agile methodology, which is the preferred method defined by SAP, needs to be followed by SAP professional services and all the certified implementation partners. This methodology has been proven to be most successful. The Agile methodology is an iterative approach. Iterative approach is a way of breaking down the system development of a large application into smaller chunks. In iterative development, functionality is designed, configured and tested in repeated cycles.

  • A Systematic Review on Regression Testing for Web-Based Applications
    Journal of Software A Systematic Review on Regression Testing for Web-Based Applications Anis Zarrad* Department of Computer Science and Information Systems, Prince Sultan University, Riyadh, Saudi Arabia. * Corresponding author. Tel.: +966114948531; email: [email protected] Manuscript submitted December 12, 2014; accepted April 16, 2015. doi: 10.17706/jsw.10.8.971-990 Abstract: Web-based applications and their underlying parts are growing rapidly to offer services over the internet around the world. Web applications play critical roles in various areas such as community development, business, academic, sciences etc. Therefore their correctness and reliability become important factors with each succeeding release. Regression testing is an important means to ensure such factors for every new released version. Regression testing is a verification process to discover the impact of changes in other interconnected modules. With the goal of selecting an appropriate regression testing approach to respond adequately to any changes in Web applications, we conduct a complete systematic study of regression testing techniques in Web applications. Out of 64, we identified a total of 22 papers reporting experiments and case studies. We present a qualitative analysis for used tools, an overview of test case section techniques and empirical study evaluation for every selected work. No approaches were found clearly superior to other since results depend on many varying factors and the deployment environments. We identified the need of evidences where approaches are evaluated cost effective rather than technical description. Key words: Regressing testing, web-based application testing, empirical study, test set, software testing. 1. Introduction In today’s scenario, as the world became global and with the advent of internet technologies, Web-based applications become more effective manner for enterprises, and academic entities to produce business strategies and policies.

  • A Brief Essay on Software Testing
    1 A Brief Essay on Software Testing Antonia Bertolino, Eda Marchetti Abstract— Testing is an important and critical part of the software development process, on which the quality and reliability of the delivered product strictly depend. Testing is not limited to the detection of “bugs” in the software, but also increases confidence in its proper functioning and assists with the evaluation of functional and nonfunctional properties. Testing related activities encompass the entire development process and may consume a large part of the effort required for producing software. In this chapter we provide a comprehensive overview of software testing, from its definition to its organization, from test levels to test techniques, from test execution to the analysis of test cases effectiveness. Emphasis is more on breadth than depth: due to the vastness of the topic, in the attempt to be all-embracing, for each covered subject we can only provide a brief description and references useful for further reading.

  • Software Engineering
    SOFTWARE ENGINEERING FUNDAMENTALS OF SOFTWARE TESTING Software testing is the evaluation of a system with the intention of finding an error or fault or a bug. It also checks for the functionalities of the system so that it meets the specified requirements. LEARNING OBJECTIVES • To execute a program with the intent of finding an error. • To check if the system meets the requirements and be executed successfully in the intended environment. • To check if the system is “Fit for purpose”. • To check if the system does what it is expected to do. STAGES OF TESTING Various testing is done during various phases of the development cycle such as: Module or unit testing. Integration testing, Function testing. Performance testing. Acceptance testing. Installation testing. UNIT TESTING Unit testing is the testing and validation at the unit level. Unit testing validates and tests the following: Algorithms and logic Data structures (global and local) Interfaces Independent paths Boundary conditions Error handling Formal verification. Testing the program itself by performing black box and white box testing. INTEGRATION TESTING One module can have an adverse effect on another. Sub-functions, when combined, may not produce the desired major function. Individually acceptable imprecision in calculations may be magnified to unacceptable levels. Interfacing errors not detected in unit testing may appear in this phase. Timing problems (in real-time systems) and resource contention problems are not detectable by unit testing. Top-Down Integration The main control module is used as a driver, and stubs are substituted for all modules directly subordinate to the main module. Depending on the integration approach selected (depth or breadth first), subordinate stubs are replaced by modules one at a time.
