In industry it is usual to develop a family of similar software instead of a single one. Software product-line (SPL) engineering or family-based software engineering is an approach that tries to minimize needed effort and time-to-market and maximize quality of manufactured products through strategic planning for maximizing reuse among members of the family. On the other hand it is known that testing software is an indivisible part of software development process which requires considerable time and effort. With large number of products created from an SPL, it is obvious that testing should be conducted in such a way that needed effort does not maintain a linear relationship with number of... 

Software development process is a base ground for all software activities and ensures all aspects of the software. No quality is guaranteed without a definite process. Model-Driven Software Development process proposes an industrial method for software companies to produce the required software through model(s) and tools. On the other hand, Software Product Line imposes a set of frameworks and principles. As a result a tangible decrement of development time and cost along with an increment of quality is achieved. Mixing both processes creates a stronger industrial process in order to decrease the development time and cost. In this thesis, through a survey on both of the processes and related... 

Software Product Line is known as a process of developing family of the software together. The methods of building a software product line is trying to capture commonality and variety of this family of software and form a product line based on them. Commonality of this family of the software allows us reuse in every aspect of the development of software. Nowadays, software architecture as a one of the most important aspect of software engineering, plays major role in specifying the tasks and clearing the relationship between people. It can divide large and complex system to some sub-system and overcome complexity of the system. Software architecture forms a basis for communication among... 

Software product line (SPL) engineering offers several advantages such as reduced costs, high quality and less time to market in development of family of software products. The goal of software product line is systematic and effective development of a set of software products which share common and managed set of features. Software product line testing has its special challenges such as scalability and variability, and has significant importance due to the importance of quality in software product line and enormous number of possible products. Most of the popular methods in this domain have shortcomings such as having seam between development and testing processes, limited application scope... 

Nowadays Software product line technology receives notable considerations due to great advantages of cutting the costs and time to market, and improvement of the quality of software products. Variability plays a key role in software products line. Quality attributes can be a source of variability in software products line, therefore having an approach to manage them is essential. Quality attributes should be considered in all parts of software development life cycle, started by capturing and modeling in an appropriate way, mentioning in architecture design and being used in final products configurations. In this research at first, the necessity of study of quality attributes in software... 

Software Product Line Engineering (PLE) and Agile Software Development are two leading approaches in the software industry. Despite the inherent differences between the two approaches, they are intended to fulfill common goals, such as: Reducing time to market, increasing customer satisfaction, promoting product quality, managing changes in requirements, and lowering the costs of development. In addition, each of them has certain positive features which address the other’s weaknesses. As a result, it seems reasonable to integrate the two approaches in order to produce a combined method which fulfills the common goals while addressing the weaknesses. Agile Product Line Engineering (APLE) is a... 

With the advent of software product lines as a practical approach in software engineering, research on this area has increased exponentially. In Software product lines a platform is presented onto which a product family can be created with ease. With the help of this platform each software in the product family can be produced with small modifications. Using this approach, cost and time of producing software decreases whilst at the same time increasing the overall software quality. Changes in standards, instability in business needs and variable requirements of various stakeholders will always cause evolution in a software product line. These change areas cannot always be predicted by... 

In the current decade there has been research works around adopting agile methodologies for software product line engineering. However, the emphasis has been on the process part of the methodology and the main product which is the source code has been neglected.The prevalent modeling and implementation method of software product line is the featureoriented method. The concept of ”Feature-to-code mapping” is introduced in the implementation phase which recently novel approaches have been proposed to realize it.Despite superiority of the novel approaches in this field, prevalent industrial product lines still use C language and map features to code by leveraging traditional preprocessors of C... 

Employing Software Product Lines (SPLs) is an effective strategy for enabling and benefiting from software reuse. This strategy also greatly increases the number and types of artifacts. Managing these artifacts over the lifetime of the product line requires a highly effective Configuration Management (CM) process. This process is more complex for product lines compared to single systems. This is due to the special property of SPLs, in which the CM process must oversee the changes made to all artifacts under its control, especially the Core Assets, since two products may share the same Core Assets, and hence, changing one of them may affect the other. In addition, the CM in SPLs normally... 

One of approaches in software architecture design is using architecture styles or patterns. This approach is a suitable way for satisfying functional and nonfunctional requirements and also is cost effective. It is shown that this approach improves effectively quality of software systems. Whereas, choosing a suitability architecture style for complex designs depends on many factors and often one style cannot meet all the requirements, therefore, use of heterogeneous styles can be useful. Also, in software product line architecture design, we must combine different kinds of architectural styles to cover the problem domain and achieve better performance. Correct and accurate choice of...
