Yannick Ongena did a greate job on this book with a uniqe style of teaching. In this book topics are covered with 4 dimensions.
"How to do it..."
"How it works..."
and "There's more..."
With this way of teaching, the prerequests for testing the case are defined, the way to implement the topic on WebCenter is defined, "what is happening behind the scenes" is explained and the details of the issue are told. I think this is a great way of explaning a test case.
As you can guess from the name of the book, this book is not a classic definition book, it descibes the topics with test cases (recipes in writer's naming) and if you not just read it but implement on your own WebCenter environment, it'll help you a lot to develop your administration skills. Book starts with creating an Enterprise Portal with WebCenter with the following test cases:
Preparing JDeveloper for WebCenter
Creating a WebCenter portal
Changing the look and feel of your portal
Editing pages using the composer.
All chapters include the relevant test cases and screen views. You'll find the following chapters in the book:
Chapter 1: Creating an Enterprise Portal with WebCenter
Chapter 2: Consuming Portlets
Chapter 3: Navigation Models and Page Hierarchies
Chapter 4: Managing the Resource Catalog
Chapter 5: Managing the Look and Feel of Your Portal
