In the creation of the training courses and the materials that make up this book, I have drawn on all the experiences I have had an author, practitioner, consultant, and trainer. So I have benefited from individuals too numerous to list. I thank each of you who have bought one of my previous books, for you contributed to my skills as a writer. I thank each of you who have worked with me on a project, for you have contributed to my abilities as a test manager, test analyst, and technical test analyst.
I thank each of you who have hired me to work with you as a consultant, for you have given me the opportunity to learn from your organizations. I thank each of you who have taken a training course from me, for you have collectively taught me much more than I taught each of you. I thank my readers, colleagues, clients, and students and hope that my contributions to each of you have repaid the debt of gratitude that I owe you.
From humble beginnings, RBCS has grown into an international consulting, training, and outsourcing firm with clients on six continents. While I have remained a hands-on contributor to the firm, over employees, subcontractors, and business partners have been the driving force of our ongoing success. I thank all of you for your hard work for our clients.
Without the success of RBCS, I could hardly avail myself of the luxury of writing technical books, which is a source of great pride but not a whole lot of money. Again, I hope that our mutual successes together have repaid the debt of gratitude that I owe each of you. Finally, I thank my family, especially my wife, Laurel, and my daughters, Emma and Charlotte. The hectic work schedule entailed in running a global testing services company means little time for my family, and my insatiable habit of writing books reduces that time further.
To Laurel, Emma, and -Charlotte, know that I am aware that I can never fully repay the debt that I owe you for all that you give to me, but also know that my love for each of you is much greater than the time we get to share together. Preface I've worked as a software engineer for 25 years. When I started as a programmer, I learned to unit test my code as I wrote it. When I became a professional tester 20 years ago, I tested my own code and other people's code.
I received my degree in software engineering in the s at the University of California, Los Angeles, which is a prestigious university.
However, I learned very little about testing there. So when I became a professional tester, I found that I had to teach myself the skills, both from books and from experience. In the s, software testing was just emerging as a separate discipline within software engineering. It's no surprise that universities, even prestigious universities, would not provide much education on the topic of software testing at that time.
Unfortunately, software testing education at universities and colleges has not advanced much in the intervening 20 years. Training on software testing from private firms, including my own company, RBCS, has helped fill that gap. However, practitioners often obtain education in a piecemeal fashion, without continuity between subjects. Therefore, many practitioners of software testing remain self-taught, or educated in disparate concepts without a unifying set of ideas to help them understand that whole field.
This has created a situation in which many practitioners do not understand the foundational and advanced concepts of software testing. The International Software Testing Qualifications Board ISTQB is address-ing this situation by defining a set of syllabi or bodies of knowledge, if you prefer that suggest what practitioners should know at various points in their careers as software testing professionals. IntroductionThis is a book on advanced software testing for test managers.
By that I mean that I address topics that a practitioner who has chosen to manage software testing as a career should know. I focus on those skills and techniques related to test analysis, test design, test execution, and test results evaluation. I assume that you know the basic concepts of test engineering, test design, test tools, testing in the software development lifecycle, and test management.
You are ready to mature your level of understanding of these concepts and to apply these mature, advanced concepts to your daily work as a test professional. You can use this book to self-study for those exams or as part of an e-learning or instructor-led course on the topics covered in those exams. However, even if you are not interested in the ISTQB exams, you will find this book useful to prepare yourself for advanced work in software testing.
If you are a test manager, test director, test analyst, technical test analyst, automated test engineer, manual test engineer, programmer, or in any other field where a sophisticated understanding of software test management is needed, then this book is for you. This book focuses on test management.
The book consists of 11 chapters, addressing the following material: Preparing for the examSince that structure follows the structure of the ISTQB Advanced syllabus, some of the chapters address the material in great detail because they are central to the test manager role. Some of the chapters address the material in less detail because the test manager need only be familiar with it.
For example, we cover test management in detail in this book because that is central to what a test manager does, while we spend less time on test techniques. The second issue is the common problem of development groups, likewise pressured to achieve dates, delivering unstable and often untestable systems to the test team. This problem causes significant portions of the test schedule to be consumed by what is, effectively, retroactive unit testing. When compounded with a lack of adequate configuration management, this situation can render the high-level testing almost pointless, because what is delivered doesn't work and isn't even understood in terms of composition.
A third issue is the common failure to include the activities shown in the crossbars of the V-model in figure ; instead, due to other projects or a lack of management awareness, the test team is involved late. Very little preparation time is allowed. Testing typically devolves to an ad hoc or at best reactive strategy, with no defect prevention, no clear coverage, and limited value. These sequential lifecycle issues are surmountable, but they require careful test management. You'll learn more about how to manage such issues in this book.
Iterative or Incremental Lifecycle ModelsIterative or incremental models are those where the system is built and tested iteratively in chunks, as shown in figure The grouping of functions and capabilities into chunks can be done based on risk, in that the functions and capabilities that are most likely to fail get built in the first chunk, then the next most likely to fail, and so forth.
The grouping into chunks can be done based on customer priority so that the functions and capabilities most desirable to customers get built first, the least desirable last, and the others at some chunk in between. During the design phase, we did static performance tests of proposed designs, which basically consisted of reviews of spreadsheet models of load and performance.
Once those tests were done-but still during the design phase-we did static performance analysis, using commercial simulation tools, of the proposed designs.
As programming progressed, programmers were responsible for doing unit performance tests as they implemented the design. The harnesses used for these tests were also used to build system performance test tools. Finally, once we had a feature-complete system, we started system test. We followed a sequential lifecycle on this project.
At this point, we did system performance tests of the implemented design. This approach reduced the number of serious performance problems found during system test to a manageable number.
That's not to say we didn't find performance defects-we found over a dozen-but they were all of the sort that could be fixed quickly and without major changes to the design, or the schedule.
Let's look at an example of how development and test tasks interact in the lifecycle. This example is from a large, complex project to develop a system of systems providing an entertainment network in North America.
Entry criterion 1 requires that the preintegration test phase has exited. This was an informal test phase design to check, on a risk-driven basis, whether various intersystem interfaces were working properly. Entry criterion 2 requires that we have final, approved versions of the primary specification documents. This has a lifecycle assumption embed-ded in it, which is that we are following a lifecycle that would produce such documents.
Entry criterion 3 requires approval of the system integration test plan and the system integration tests. The development and project management teams were to review these documents and provide approval, which was to align development and test activities. Entry criterion 4 requires that the live system be set up for testing. The lifecycle assumption here is that we would have access to the live system and that it would be ready well in advance of going into production so that we could use it for testing.
Obviously, this is a unique criterion, one that only people Continuing to move up the pyramid, we come to system integration testing.
Now, finally, we are talking about a single test level across all systems. Next above that we find systems testing, focusing on end-to-end tests that span all the systems. Finally, we have user acceptance testing. For each of these test levels, while we have single organizational ownership, we probably have separate team ownership. Table shows an example of what we called "preintegration testing" on a complex system of systems project to deliver an entertainment system in North America.
The system of systems consisted of seven main systems, labeled A through G in this table: Case Study of a System of Systems ProjectThe interactive voice response server hardware itself, a custom serverThe local and wide area networks tying the systems togetherThe interactive voice response server application, being the software running on the IVR servers that actually interacted with customers The customer service application, which ran in the call center, allowing agents to handle calls from customers, particularly if they had trouble using the system The call center infrastructure, such as the computer-telephony integration suitesThe data warehouse that stored transaction information on the customers, along with other business intelligence informationThe content management software that managed all the content on the servers Preintegration testing was the name we gave to the phase of testing that preceded system integration testing.
In this phase, we identified six main builds, which we called backbones. Each build allowed testing of one or more interfaces between the systems. The letter corresponds to the system; the number is a sequence number for the interface.
Notice that some interfaces are used by one system to interact with more than one other system. For example, the call center's E1 interface interacts with the IVR application and the content management system in backbone zero. The objective of this exercise, as you probably have guessed, was to test as many critical interfaces as possible before formal system integration testing.
This early testing would allow us to find dangerous-and potentially design-threatening-defects before formal integration testing started so we could eliminate them. Safety-Critical SystemsSimply put, safety-critical systems are those systems upon which lives depend. Failure of such a system-or even temporary performance or reliability degradation or undesirable side effects as support actions are carried outcan injure or kill people. Safety-critical systems, like systems of systems, have certain associated characteristics and risks, including the following:Because defects can cause death, and deaths can cause civil and criminal penalties, so proof of adequate testing can be and often is used to reduce liability.
For obvious reasons, various regulations and standards often apply to safety-critical systems. The regulations and standards can constrain the process, the organizational structure, and the product.

Слова, сорвавшиеся с его языка, были определенно произнесены на английском, но настолько искажены сильным немецким акцентом, что их смысл не сразу дошел до Беккера. - Проваливай и умри. Дэвид даже вздрогнул от неожиданности. - Простите. - Проваливай и умри, - повторил немец, приложив левую ладонь к жирному правому локтю, имитируя итальянский жест, символизирующий грязное ругательство. Но Беккер слишком устал, чтобы обращать внимание на оскорбления.
Его глаза не отрывались от губ Клушара. Он еще раз сжал его руку, но тут наконец подбежала медсестра. Она вцепилась Беккеру в плечо, заставив его подняться - как раз в тот момент, когда губы старика шевельнулись. Единственное сорвавшееся с них слово фактически не было произнесено. Оно напоминало беззвучный выдох-далекое чувственное воспоминание. - Капля Росы… Крик медсестры гнал его прочь. Капля Росы.
Он стремительно развернулся и едва сдержал крик. Никого.
Вторично разоблачив попытку АНБ пристроить к алгоритму черный ход, Грег Хейл превратится в мировую знаменитость. И одновременно пустит АНБ ко дну. Сьюзан внезапно подумала, что Хейл, возможно, говорит правду, но потом прогнала эту мысль. Нет, решила .
Он схватил убитого за запястье; кожа была похожа на обгоревший пенопласт, тело полностью обезвожено. Коммандер зажмурился, сильнее сжал запястье и потянул. Труп сдвинулся на несколько сантиметров. Он потянул сильнее. Труп сдвинулся еще чуть-чуть.
Но когда ТРАНСТЕКСТ расшифровал эти потоки информации, аналитики тут же увидели в них синхронизированный через Интернет отсчет времени. Устройства были обнаружены и удалены за целых три часа до намеченного срока взрыва. Сьюзан знала, что без ТРАНСТЕКСТА агентство беспомощно перед современным электронным терроризмом. Она взглянула на работающий монитор.
