...Chapter 16 – Software Quality Assurance Overview This chapter provides an introduction to software quality assurance. Software quality assurance (SQA) is the concern of every software engineer to reduce costs and improve product time-to-market. A Software Quality Assurance Plan is not merely another name for a test plan, though test plans are included in an SQA plan. SQA activities are performed on every software project. Use of metrics is an important part of developing a strategy to improve the quality of both software processes and work products. Software Quality Assurance • Umbrella activity applied throughout the software process • Planned and systematic pattern of actions required to ensure high quality in software • Responsibility of many stakeholders (software engineers, project managers, customers, salespeople, SQA group) SQA Questions • Does the software adequately meet its quality factors? • Has software development been conducted according to pre-established standards? • Have technical disciplines performed their SQA roles properly? Quality Assurance Elements • Standards – ensure that standards are adopted and follwed • Reviews and audits – audits are reviews performed by SQA personnel to ensure hat quality guidelines are followed for all software engineering work • Testing – ensure that testing id properly planned and conducted • Error/defect collection and analysis – collects and analyses error and defect data to better...

...A Software Quality Assurance and Management System Er.Ashish Kumar Tripathi, Er. Sachin Kumar Dhar Dwivedi, Mr. Saurabh Upadhyay Abstract- Software quality objectives covers a variety of techniques and measurements, including gathering code metrics, enforcing coding rules, and proving the absence of run-time errors. The guide also takes into account the origin of the code, its stage in the software life cycle, and the safety aspects of the application. The guide explains how to gradually adapt the code verification process to achieve targeted quality objectives Index Terms- Application and System S/W, System efficiency, testing and good designing tools. -------------------------------------------------------- 1-Introduction Quality assurance for automotive systems can require different types of verification activities throughout the development process. Early verification focuses on evaluating intermediate software builds and removing defects at coding time. This represents an emerging trend because performing verification early in the process can improve overall quality and reduce development time. Post-production verification focuses on evaluating final build quality or finding defect root causes after the product is complete. This is the most common approach to automotive system verification. 3-About Software ProductsSoftware products may be • Custom - developed for a particular customer, according to its specifications Generic (“package”) - developed for...

...Leveraging Existing Tests in Automated Test Generation for Web Applications Amin Milani Fard Mehdi Mirzaaghaei University of British Columbia Vancouver, BC, Canada Ali Mesbah {aminmf, mehdi, amesbah}@ece.ubc.ca ABSTRACT To test web applications, developers currently write test cases in frameworks such as Selenium. On the other hand, most web test generation techniques rely on a crawler to explore the dynamic states of the application. The first approach requires much manual effort, but benefits from the domain knowledge of the developer writing the test cases. The second one is automated and systematic, but lacks the domain knowledge required to be as effective. We believe combining the two can be advantageous. In this paper, we propose to (1) mine the human knowledge present in the form of input values, event sequences, and assertions, in the human-written test suites, (2) combine that inferred knowledge with the power of automated crawling, and (3) extend the test suite for uncovered/unchecked portions of the web application under test. Our approach is implemented in a tool called Testilizer. An evaluation of our approach indicates that Testilizer (1) outperforms a random test generator, and (2) on average, can generate test suites with improvements of up to 150% in fault detection rate and up to 30% in code coverage, compared to the original test suite. these interactions at runtime is manifested through the Document Object Model (DOM) and presented to the end-user in...

...CSC 415 / Software Engineering Date of Submission: September 20, 2013 Software Quality Assurance and Testing Techniques Subject: This memo delves into unit testing, integration testing, and other aspects of software quality assurance. Software quality assurance is essential for any business that provides products that are to be used by others. This memo serves as a documentation of software testing methodologies that support a recommendation for GF Software Solutions approach to SQA. Addressed are various components of the software development lifecycle and the different techniques that exist for their implementation. Unit tests focus on the verification of the smallest unit of software design, or the software module. Integration testing can be performed using a number of different methods including top-down, bottom-up, and big bang integration. Integration tests address problems or bugs that may occur when interfacing individual software components and building the complete system architecture. System tests are applied when the software is incorporated with other systems elements such as hardware, people, or information. Stress testing is a method of determining the stability of an application when tested beyond the bounds of normal operation. Each of the aforementioned steps is crucial to the software quality assurance procedure and is defined more thoroughly in the following sections. A critical component of software quality assurance...

...2277-8616 44 IJSTR©2015 www.ijstr.org A Framework For Software Quality Assurance Using Agile Methodology Maria Sagheer, Tehreem Zafar, Mehreen Sirshar Abstract: Agile methodology that uses iterative and incremental approach is widely used in the industry projects as they can satisfy to the change of requirements. Efficient product delivery is achieved by using short iterations. But assuring the quality in any system is essential and imperative part which is very difficult task, which raises a question that: Is quality is assured in the software which is developed using agile methodology? The research paper proposed a solution and summarizes that how the quality is achieved or assure in agile software development using different factors. The major focus of this research paper is to analyse the quality parameter which assure quality in the agile methodology. The research paper includes the brief overview of the parameters which assure quality in agile. ———————————————————— I. INTRODUCTION. For the successful software engineering, the delivery of high quality software is needed. Mainly the customer satisfaction level is considered as the quality attribute which defines high quality of any system. Traditionally waterfall approach is used for the software development in which system is developed by freezing the requirements. To achieve high quality Agile methods rather than waterfall approach for the software development are adapted by many organizations to compete...

...Difference between QA and QC As we've talked in a previous post about the Definition of Quality, with these 2 terms exist the same “issue” where every single person/organization defines Quality Assurance (QA) and Quality Control (QC) in a bit different way. Also, many people including HHRR (Human Resources) and quality professionals do not know what QA and QC really means, and what the difference is between both terms. For those reasons, these concepts are often used interchangeably, and in some organizations one department performs the activities of both. The truth is that both terms have strong interdependence; QA relies mostly on the QC feedback and both work to deliver good quality products/services; but they are different processes. Next table shows the differences between them. QA vs. QC Definition from ASQ.org Assurance: The act of giving confidence, the state of being certain or the act of making certain. QA: The planned and systematic activities implemented in a quality system so that quality requirements for a product or service will be fulfilled. Other definition QA is a failure prevention system that predicts almost everything about product safety, quality standards and legality that could possibly go wrong, and then takes steps to control and prevent flawed products or services from reaching the advanced stages of the supply chain. Definition from ASQ.org Control: An evaluation to indicate needed corrective responses; the act of guiding...

...THE CASE FOR INTERNAL SOFTWARE QUALITY While this might look like stating the obvious, I still find that there are organisations especially in this part of the world (Nigeria) that have not really imbibed software quality assurance practices. From experience, I find that its because management has not really taken a serious look into the merits and demerits of internal software quality. What is internal software quality and what how does it differ from Just plain Software Quality? When it comes to software quality assurance, it is most commonly viewed in two aspects (There could be more). • External software quality. • Internal software quality. This is derived from Steve McConnell's division of software characteristics in external and nternal characeteristics. External software quality refers to the parts of software that face a user. These refer to: • Functionality • Usability • Reactivity • Security • Availability • Reliability All these aspects of software quality can verified by testing the software as a whole – end-to-end tests. Most often this is the aspect of the software that users and non technical management focus on. Is it doing what the user wants it to do? While this is both ok and required, it is not enough to ascertain the quality of an application. Internal Software Quality refers to the quality of the source code itself. These refer to: • Application Architecture Practices • Coding Practices • Application Complexity • Documentation • Portability • Technical &...
