The widespread adoption of agile methods has brought the need for effective testing into the limelight, and agile projects have transformed the role of testers. Much of a tester´s function, however, remains largely misunderstood. What is the true role of a tester? Do agile teams actually need members with QA backgrounds? What does it really mean to be an ´´agile tester?´´ Two of the industry´s most experienced agile testing practitioners and consultants, Lisa Crispin and Janet Gregory, have teamed up to bring you the definitive answers to these questions and many others. In Agile Testing, Crispin and Gregory define agile testing and illustrate the tester´s role with examples from real agile teams. They teach you how to use the agile testing quadrants to identify what testing is needed, who should do it, and what tools might help. The book chronicles an agile software development iteration from the viewpoint of a tester and explains the seven key success factors of agile testing.

Der Trend zu agilen Vorgehen ist ungebrochen Dieser Trend geht auch am Softwaretest nicht spurlos vorüber. Nachdem die Bedeutung des Tests in agilen Projekten unumstritten ist, treten jetzt vor allem die Professionalisierung und die Integration der einzelnen Mitarbeiter in den rollenübergreifenden Tätigkeiten des agilen Vorgehens in den Vordergrund. Die klassischen Rollenbilder des Tests verschwimmen und gehen ineinander über. Die Eigenverantwortung der Tester steigt. Für den klassischen Tester bedeutet dies eine Bereicherung und Aufwertung seiner Rolle, da er auch Aufgaben und Tätigkeiten anderer Professionen übernimmt. - Der Stellenwert des Teams - Die Crux mit den Werkzeugen in agilen Projekten - Die sieben schlechtesten Ideen für die Testautomatisierung - Testmethoden im agilen Umfeld - Tester: Generalist vs. Spezialist? Welches sind nun aber die Aufgaben des Softwaretests in agilen Projekten? Wie sind diese in unterschiedlichen agilen Vorgehensweisen - wie etwa Scrum oder Kanban - zu organisieren? Welche Bedeutung haben Testwerkzeuge in diesem Kontext? Wie grenzen sich die Verantwortlichkeiten gegeneinander ab oder wirken synergetisch zusammen? Auf diese sehr konkreten Fragen, die sich im operativen Projektgeschehen immer wieder stellen, liefert dieses Buch mögliche Antworten, ergänzt durch bewährte Ansätze aus der Praxis.

Professional testing of software is an essential task that requires a profound knowledge of testing techniques. The International Software Testing Qualifications Board (ISTQB) has developed a universally accepted, international qualification scheme aimed at software and system testing professionals, and has created the Syllabi and Tests for the Certified Tester. Today about 300,000 people have taken the ISTQB certification exams. The authors of Software Testing Foundations, 4th Edition, are among the creators of the Certified Tester Syllabus and are currently active in the ISTQB. This thoroughly revised and updated fourth edition covers the Foundation Level (entry level) and teaches the most important methods of software testing. It is designed for self-study and provides the information necessary to pass the Certified Tester-Foundations Level exam, version 2011, as defined by the ISTQB. Also in this new edition, technical terms have been precisely stated according to the recently revised and updated ISTQB glossary. Topics covered: - Fundamentals of Testing - Testing and the Software Lifecycle - Static and Dynamic Testing Techniques - Test Management - Test Tools Also mentioned are some updates to the syllabus that are due in 2015.
