Seam 2.x Web Development

Overview of this book

The Seam framework from JBoss allows developers to use JSF, Facelets, EJB, and JPA to write conversational web applications. But you will first have to learn how these standard technologies are integrated using Seam and how they can be built upon using additional Seam components. If you need to build a Java web application fast, but don't have time to learn all these complex features, then this book is for you. The book provides a practical approach to developing Seam applications highlighting good development practices. It provides a complete walk through to develop Web applications using Seam, Facelets, and RichFaces and explains how to deploy them to the JBoss Application Server. You can start using key aspects of the Seam framework immediately because this book builds on them chapter by chapter, finally ending with details of enterprise functionality such as PDF report generation and event frameworks. First, the book introduces you to the fundamentals of Seam applications, describing topics such as Injection, Outjection and Bijection. You will understand the Facelets framework, AJAX, database persistence, and advanced Seam concepts through the many examples in the book. The book takes a practical approach throughout to describing the technologies and tools involved. You will add functionality to Seam applications after you learn how to use the Seam Generator RAD tools and how to customize and fully test application functionality. Hints and tips are provided along the way of how to use Seam and the JBoss Application Server.

Preface

Testing the user interface


Unit testing allows us to perform discrete tests on classes and groups of classes to see how they all work in isolation from the application as a whole. Unit testing provides an excellent way to test our classes in isolation, but doesn't allow us to test any interaction between classes, components, or user interfaces. It is useful, therefore, to be able to run integration tests on components and on the user interface, showing the interaction of the classes when events such as buttons on forms are clicked. Traditionally, this type of testing is performed within the container.

To perform this testing, the application needs to be built, deployed, and then tested. However, Seam makes this process easy by allowing us to perform integration tests of this type, outside of the container. Seam is supplied with an embedded version of JBoss, which can be found within the bootstrap directory of SeamGen generated projects. When you run integration tests with Seam, the tests...
