    • Short Course Topic: Advances in Component-Based Software Testing - Issues, Challenges, Solutions and Techniques By Jerry Zeyu Gao, Ph.D. San Jose State University Schedule: January 16-18, 2006, Cost: $1000/per person Location: San Jose State University Contact: Jerry Gao at jerrygao@email.sjsu.edu URL: http://www.engr.sjsu.edu/gaojerry Motivation: Widespread development and reuse of software components has been regarded by many as one of the next biggest phenomena for software. Reusing high-quality software components in software development has the potential of drastically improving the quality and development productivity of component-based software. However, widespread reuse of a software component with poor quality may literally lead to disasters. Component-based software engineering involves many unique characteristics, some of which have caused new issues, challenges, and needs in testing and quality assurance of components and component-based software. Improper reuse of software components of good quality may also be disastrous. Testing and quality assurance is therefore critical for both software components and component-based software systems. Although a number of recent books address the overall process of component-based software engineering and specific methods for requirements engineering, design, and evaluation of software components and component-based software. However, only a few of published papers focuses on testing and quality control of reusable software components and component-based software systems. The primary goal of this tutorial is to discuss the issues, challenges and needs in testing of components and component-based software. Moreover, this tutorial reports the recent advances and research efforts in developing new solutions to solve those problems and meet the needs. Instructional Objectives: This tutorial course provides an in-depth insight look at the technical issues and managerial aspects of testing software components and component-based programs from the perspectives of component-based software engineering. You will learn the state-of-the-art practice, issues and challenges, new solutions and research efforts in component testing, component-based program validation, and test automation. .
    • At the end of the tutorial, the participants will know: ♦ What are the major differences between conventional software modules and modern software components? What are the new issues and challenges in testing software components for component-based software engineering projects? ♦ What are the major differences between conventional software and component-based software? Why is component-based software testing important? What are the new issues and challenges in testing component-based software? ♦ What is component testability? How to increase component testability by developing built-in and testable software components? ♦ What are the applicable unit testing methods for components in component-based software engineering? ♦ How to conduct integration and regression testing for component-based software? What are the issues and solutions in component integration, regression testing of component-based software? ♦ How to conduct performance testing and measure the performance of component-based software and its components? ♦ What are the current advances and research efforts in component-based software testing? Audience: The targeted audience includes technical managers, software testing engineers, quality assurance people, and development engineers who are working on component-based software projects. In addition, the tutorial is designed to help software engineering researchers and graduate students to learn the basic issues and challenges as well as new solutions in testing of third-party components and component-based programs. The tutorial will be very useful for professionals who are interested in understanding the general concepts and methods in component testing and component-based software validation. Prior Knowledge: This tutorial assumes that participants have the general understanding about the basic concepts of software engineering and software testing methods, and have some working experience in software development and validation.
