presented by Wonil Kwon, Executive Director, STA Consulting Inc, South Korea

MIMOS, Malaysia

Ashok Sivaji graduated with a Bachelor of Electrical & Electronic Engineering from the University of Adelaide, Australia in 2000. He joined Agilent Technologies and gained valuable experience both in Santa Rosa, US & Penang , Malaysia as a test software & hardware engineer. He developed a strong interest in test infrastructure & application development. In 2004-2006, he joined Texas Instrument Malaysia as a Senior Test engineer. He was the lead test engineer to transfer & setup test infrastructure from Taiwan, Japan & US . He presented a paper “Measurement System Analysis” in the Third IEEE International Workshop organized by IEEE Computer Society. In 2006, he was promoted to lead and manage a team of test engineers in Agilent Technologies. He was awarded a merit award for the development of an Oscilloscope Pretest Test Solution. He was also involved in the test application development and standardization across multiple product lines. Due to career interest in software, he joined MIMOS Berhad, where he has been serving as a Usability Lab Head. He has organized and presented in the MIMOS Usability Workshop 2009, “Innovations in Usability Testing”.

Economic recession necessitated many changes in IT companies, and optimizing test cases and reducing the cost of testing are few of those changes. As per Gartner and other research journals, 80% of changes that happen in software products are defect fixes. Hence optimizing the regression testing can give better return on investment for any testing team. Regression testing is very important for the quality of the product, as this is the testing which ensures the exact product/build that is tested reaches the customer. The idea of regression is not only to test the defect fixes but also to ensure there are no side effects because of defect fixes. Testing for side effects becomes critical, as this needs several skills on product domain and testing technologies. A methodology for an effective regression testing requires several steps to select test cases properly as one can't decide the scope based on number of defect fixes or criticality of defect fixed. Selection of test cases for regression testing depends more on the criticality of defect fixes than the criticality of the defect itself. A minor defect can result in major side effect and a defect fix for an Extreme defect can have no or a minor side effect. It is a good approach to plan and act for regression testing from the beginning of project before the test cycles and that leaves only selection of specific test cases just before regression test cycles. Having a constant set of test cases for regression testing may not be a good idea. A good approach also involves the test cases categorized in to different priorities and resetting the results of test cases at different times. The presentation is aimed at explaining the planning, designing test cases and concluding results of regression testing.

The content of the tutorial is based on best practices paper presented at Washington, USA part of the PSQT/PSTT conference conducted by International Institute of Software Testing (IIST). This tutorial brings in the principles and practices from one of the best selling book “Software Testing – Principles and practices” authored by the presenter.  There is also a patent submitted on “Regression Methodology” by the author of this book.

• Basic concept and definition of regression testing
• Types of regression testing
• How to select test cases for regression testing
• Methodology and practical approach for effective regression testing
• How to conclude the results of regression testing

Srinivasan has authored one of the best selling book titled 'Software Testing-Principles & Practices' published by Pearson Education, India, available both in English and Chinese languages. This book is being used by more than 40 universities in India and abroad. Some of his interesting articles and publications can be accessed at: stickyminds.com and QAGuild.com. He also submitted couple of patent disclosures on testing.

Srinivasan and his book received numerous awards and the most recent being Test2008.in Award for his contribution to Academia & Industry.

The risk-based testing is prevailing (or one of the mainstreams) in the software development and testing project, but the “how to” is not concrete and shared among the testing practitioners. The practical risk-based testing strategy based on the international standard, ISO/IEC29119, Software Testing, is to be thoroughly discussed in this presentation. The testing strategies under discussion include the organizational test strategy, master test strategy, and level (or non-functional) test strategies. The value of utilizing the risk-based testing strategy will be manifested through this presentation. In addition, the core of ISO/IEC29119 software testing process will be introduced and explained based on its implementation experience in the beginning of the presentation.

ISO/IEC29119, Software Testing, incorporates the current software testing standards such as IEEE 829, BS7925-1&2, IEEE1008, etc. It will eventually supersede all other standards meaning that other national and international standards are to be changed in compliance with the ISO standard. The structure of ISO/IEC29119 and its core software testing process will be presented and discussed. The practical application, recent development, and future work are to be followed in the presentation.
