Abstract

Objectives: The software security and its proper measurement involve various tools and techniques. To make software secure its foundation stone, the requirement, should also be secure and therefore the integrity control for requirement at the same phase became the objective for delivering secure requirement and so forth the software. Method/Analysis: The past research study entails about less secure software deliver by industries and among the major cause of security lacking, one cause is integrity to requirements. Requirement integrity can be observed as trustworthy, complete and veracity requirement for producing secure software. Only conceptual notion of integrity is not capable to make any component secure but it must be depicted in understandable and quantifiable idiom for assessing the better security solution to requirement and therefore to software. Findings: MQIR (Model to quantify integrity) for requirement at requirement phase of software development process is a new assessment technique that tries to satisfy all major constraints regarding secure requirements and so forth for software. To implement this new technique a relevant set of values in terms of input is captured for proper data management from various live projects under going in some software companies of repute. An appropriate quantification of requirement data is also furnished for sufficient checking of security level and its efficiency. The technique has also been validated through capturing online shopping data so that its implications may also be assessed accurately. Novelty/Improvement: As far as the application of this technique (MQIR) is concern, the article emphasis on complete usability of online functioning at its highest level of integrity that maintains security with the boundary conditions of e-commerce.

Abstract

Measuring testability early in the development life cycle especially at design phase is a criterion of crucial importance to software designers, developers, quality controllers and practitioners. However, most of the mechanism available for testability measurement may be used in the later phases of development life cycle. Early estimation of testability, absolutely at design phase helps designers to improve their designs before the coding starts. Practitioners regularly advocate that testability should be planned early in design phase. Testability measurement early in design phase is greatly emphasized in this study; hence, considered significant for the delivery of quality software. As a result, it extensively reduces rework during and after implementation, as well as facilitate for design effective test plans, better project and resource planning in a practical manner, with a focus on the design phase. An effort has been put forth in this paper to recognize the key factors contributing in testability measurement at design phase. Additionally, testability measurement model is developed to quantify software testability at design phase. Furthermore, the relationship of Testability with these factors has been tested and justified with the help of statistical measures. The developed model has been validated using experimental tryout. Finally, it incorporates the empirical validation of the testability measurement model as the author's most important contribution.

Abstract

This paper presents a review on software quality measurement. An effort has been made to put forth the demand and dependency of quality software in our modern society. The demand has increased the size and complexity of computer software system during the past decades. The software industry is responding to the demand for high quality product by spending resources to improve the quality of software product. A brief discussion on quality and software quality has been given. Further, the discussion on measurement and software quality measurement are presented. Finally, it throws the light on the role of various software quality models and software metrics for software quality measurement.

Abstract

Testability is an important quality factor of object oriented software. Its correct measurement or evaluation always facilitates and improves the test process. A lack of testability contributes to a higher level test cost and changeable effort. However testability has always been an indefinable concept and its absolute estimation (measurement) or evaluation is a tough job. Researchers and practioners have always claimed that testability should be considered as key factors which have positive impact on software development in order to ensure the software quality customer satisfaction especially at design face. [29].

The purpose of this review report is to proposing a conceptual comparative evaluation considering the testability issues, limitation and to investigate the general testability factors and commonly accepted minimal set of testability factors with the help of the systematic literature review. In this paper initially we conduct a literature review to have broad knowledge of testability and its quality factors and associated measurements that are found exhibiting the number of different testability factors that are presented by different researchers in different perspective. Next we do a comparative analysis on software testability proposed by various experts/researchers including their contribution and limitation.

Abstract

To measure testability before the actual development starts will play a crucial role to the developer, designers and end users as well. Early measurement of testability, especially in early requirement stage to assist the developer for the further development process, and will also assures us to produce and deliver the high quality requirement that can surely reduce the overall cost and improves the quality of development process. Taking view of this fact, this paper identifies testability estimation factors namely understandability and modifiability and establishes the correlation among testability, understandability and modifiability. Further, a model is developed to quantify software testability in requirement phase and named as Requirement Testability Model of Object Oriented Software-RTMOOS. Furthermore, the correlation of Testability with these factors has been tested and justified with the help of statistical measures.
