Book Description
Testing is usually the most expensive, time-consuming and difficult activity during the development of engineering products and systems. Development testing must be performed to ensure that designs meet requirements for performance, safety, durability, reliability, statutory aspects, etc. Most manufactured items must be tested to ensure that they are correctly made. However, much of the testing that is performed in industry is based upon traditions, standards and procedures that do not provide the optimum balance of assurance versus cost and time. There is often pressure to reduce testing because of the high costs involved, without appreciation of the effects on performance, reliability. etc. Misperceptions are commonplace, particularly the idea that tests should not stress products in excess of their operating levels. The main reason for this situation seems to be that engineers have not developed a consistent philosophy and methodology for testing. Testing is seldom taught as part of engineering curricula, and there are no books on the subject. Specialist areas are taught, for example fatigue testing to mechanical engineers and digital device testing to electronics engineers. However, a wide range is untaught, particularly multidisciplinary and systems aspects. Testing is not just an engineering issue. Because of the importance and magnitude of the economic and business aspects testing is an issue for management. Testing is perceived as a high cost activity, when it should be considered as a value-adding process. The objective of this book is, therefore, to propose a philosophy of engineering test and to describe the necessary technologies and methods that will provide a foundation for all plans, methods and decisions related to testing of engineered products and systems. The book will help those who must manage and conduct this most difficult and uncertain task. It will also provide a text which can be used as the basis for teaching the principles of testing to all engineering students.

Book Description
Praise for Software Test Engineering with IBM Rational Functional Tester "Finally, a manual for the Software Test Engineer! Many manuals on the market today are geared toward developers, and none exist for Rational Functional Tester. This is one of the first manuals geared toward the Automated Test Engineer acknowledging the depth of knowledge required for a very complex job. The manual will assist all levels of test engineering with very specific steps and hands-on advice. This manual is a reference book that no Automated Test Engineer using RFT should be without!" --Penny Bowser, CTFL, CHE, QA Manager "The authors succeed in walking a line between sharing a wealth of technical knowledge and providing enough context to ensure the readers understand what they need to do and why. Novices and skilled practitioners alike should find the work a good read and a solid reference. Automating functional testing tends to receive less investment than it should, to the detriment of organizations everywhere. If the reader is seeking to improve his knowledge of Rational Functional Tester and make an impact using that knowledge, there is no better reference than this excellent distillation of years of field-proven experience." --David J. Trent, Market Manager of Process and Best Practices Segment for Rational Software, IBM "As a former manager of the group that tested IBM''s Rational Functional Tester, like a few others, I see clearly how this book can help teams multiply the benefits they derive from this product." --Ted Rivera, Senior Agile Transformation Architect, IBM Software Group "This book is a wonderful, in-depth resource for novice and expert users alike." --Brian McCall, former IBM IT Specialist "This collection of Rational Functional Tester information is a ''must have'' for anyone using this solution. Everyone from beginners to advanced users will find this book very helpful." --Lew Cote, IBM Technical Solution Architect "This much-needed book effectively describes the value of Rational Functional Tester for functional testing needs. The book is well organized, thought through, and has all the latest information. The authors are no doubt subject matter experts." --Kamala Parvathanathan, Senior Manager, IBM Rational The Indispensable Resource for Automated Testing Automated software testing has become a critical exercise, especially for developers utilizing iterative and agile methods. However, to achieve the full benefits of automated testing, teams need a deep understanding of both its principles and their testing tools. If you''re among the thousands of developers using IBM Rational Functional Tester (RFT), this book brings together all the insight, examples, and real-world solutions you need to succeed. Eight leading IBM testing experts thoroughly introduce this state-of-the-art product, covering issues ranging from building test environments through executing the most complex and powerful tests. Drawing on decades of experience with IBM Rational testing products, they address both technical and nontechnical challenges and present everything from best practices to reusable code. Coverage Includes Integrating IBM RFT into your development processes Building highly efficient test environments, test harnesses, and test scripts Using RFT Visual Editor to extend testing automation to novice users Mastering basic scripting techniques, from data capture to script synchronization Managing script data using RFT Datapools Efficiently debugging scripts using Eclipse(tm) or Visual Studio� Managing execution flow: playback settings, logic, error handling, and more Handling domains that are not supported by RFT Using advanced techniques, such as mouse delays and custom verification pointsTesting specialized software, including mainframe, SAP, Siebel, and Adobe� Flex� applications Extending RFT with external libraries Developing RFT support for third-party Java(tm) or .NET controls Using RFT in both Linux� and Windows� environments Configuring internationalized testing within the RFT framework

Book Description
n the late 1940¿s and early 50¿s, planes flew higher and faster than anyone had dreamed possible. The jet age had arrived, and along with it came turbojet and rocket-powered aircraft capable of flying beyond the speed of sound. To assess these aircraft, the Air Research and Development Command developed a series of data reduction methods, and then compiled them in this Flight Test Engineering Manual. It served as a standard technical reference for the flight test engineers, program managers, pilots and support teams for many of the X-plane programs of the 1950s. This reprint represents the first time in over fifty years that this book has been available, and the first time it has ever been made available to the public. it¿s a unique time capsule that provides insight into the era of ¿The Right Stuff¿, when slide rules and punch cards were the cutting edge, and a must-have for anyone interested in the technical aspects of flight test.

Book Description
The overwhelming majority of a software system’s lifespan is spent in use, not in design or implementation. So, why does conventional wisdom insist that software engineers focus primarily on the design and development of large-scale computing systems? In this collection of essays and articles, key members of Google’s Site Reliability Team explain how and why their commitment to the entire lifecycle has enabled the company to successfully build, deploy, monitor, and maintain some of the largest software systems in the world. You’ll learn the principles and practices that enable Google engineers to make systems more scalable, reliable, and efficient—lessons directly applicable to your organization. This book is divided into four sections: Introduction—Learn what site reliability engineering is and why it differs from conventional IT industry practices Principles—Examine the patterns, behaviors, and areas of concern that influence the work of a site reliability engineer (SRE) Practices—Understand the theory and practice of an SRE’s day-to-day work: building and operating large distributed computing systems Management—Explore Google's best practices for training, communication, and meetings that your organization can use
