With the advent of agile methodologies, testing is becoming the responsibility of more and more team members. In this new book, noted testing expert Dustin imparts the best of her collected wisdom. She presents 50 specific tips for a better testing program. These fifty tips are divided into ten sections, and presented so as to mirror the chronology of a software project.

Elfriede Dustin is the lead author of Automated Software Testing (Addison-Wesley, 1999), and Quality Web Systems (Addison-Wesley, 2002). An acknowledged expert in software engineering and testing practices, she has assisted numerous companies in the definition and implementation of QA and testing processes.

In most software-development organizations, the testing program functions as the final "quality gate" for an application, allowing or preventing the move from the comfort of the software-engineering environment into the real world. With this role comes a large responsibility: The success of an application, and possibly of the organization, can rest on the quality of the software product. A multitude of small tasks must be performed and managed by the testing team--so many, in fact, that it is tempting to focus purely on the mechanics of testing a software application and pay little attention to the surrounding tasks required of a testing program. Issues such as the acquisition of proper test data, testability of the application's requirements and architecture, appropriate test-procedure standards and documentation, and hardware and facilities are often addressed very late, if at all, in a project's life cycle. For projects of any significant size, test scripts and tools alone will not suffice--a fact to which most experienced software testers will attest. Knowledge of what constitutes a successful end-to-end testing effort is typically gained through experience. The realization that a testing program could have been much more effective had certain tasks been performed earlier in the project life cycle is a valuable lesson. Of course, at that point, it's usually too late for the current project to benefit from the experience. Effective Software Testingprovides experience-based practices and key concepts that can be used by an organization to implement a successful and efficient testing program. The goal is to provide a distilled collection of techniques and discussions that can be directly applied by software personnel to improve their products and avoid costly mistakes and oversights. This book details 50 specific software testing best practices, contained in ten parts that roughly follow the software life cycle. This structure itself illustrates a key concept in software testing: To be most effective, the testing effort must be integrated into the software-development process as a whole. Isolating the testing effort into one box in the "work flow" (at the end of the software life cycle) is a common mistake that must be avoided. The material in the book ranges from process- and management-related topics, such as managing changing requirements and the makeup of the testing team, to technical aspects such as ways to improve the testability of the system and the integration of unit testing into the development process. Although some pseudocode is given where necessary, the content is not tied to any particular technology or application platform. It is important to note that there are factors outside the scope of the testing program that bear heavily on the success or failure of a project. Although a complete software-development process with its attendant testing program will ensure a successful engineering effort, any project must also deal with issues relating to the business case, budgets, schedules, and the culture of the organization. In some cases, these issues will be at odds with the needs of an effective engineering environment. The recommendations in this book assume that the organization is capable of adapting, and providing the support to the testing program necessary for its success. Organization This book is organized into 50 separate items covering ten important areas. The selected best practices are organized in a sequence that parallels the phases of the system development life cycle. The reader can approach the material sequentially, item-by-item and part-by-part, or simply refer to specific items when necessary to gain information about and understanding of a particular problem. For the most part, each chapter stands on its own, although there are references to other chapters, and other books, where helpful to provide the reader with additio
