In writing an application, you usually deal with multiple data items related to each other, such as departments in a company, employees in a department, and so on. To deal with a group of data items, Java offers collections. A collection is an object that organizes multiple data items into a single group. As said earlier, in a real-world problem, the collections typically represent the data items that are related to each other. Collections are used to manipulate data (perform operations on it), store and retrieve data, and transfer data between methods. There is another way of looking at collections. In computer science, we define an abstract data type (ADT) as a set of objects combined with a set of operations that can be performed on the objects. When it comes to implementation of an ADT, the set of related data items is organized into a data structure and the operations are implemented in the form of methods. Java presents a unified architecture called the collections framework that makes a collection as an implementation of an ADT. The collections framework consists of three elements: Interfaces: Pretty much like abstract data types, and allow you to manipulate collections independently of the implementation details. Implementations: The concrete implementations of the collections interfaces. You can look upon them as reusable data structures. Algorithms: The methods that perform operations such as search and sorting on the objects in the data structures. You can also look upon them as reusable functionality. Let s begin by exploring the interfaces.

In other words, if there are 1,000 nodes in a mesh, each of the 1,000 nodes has a connection open to 999 other nodes at the same time This would lead to a situation where the mesh would soon start running out of resources as more nodes joined the network..

@After public void cleanup() { accountService.removeAccount(TEST_ACCOUNT_NO); } }

The root of the hierarchy of the collections interfaces is the Collection interface, also referred to as the superinterface of the collections. There is another kind of collections called maps, which are represented by the superinterface Map, which is not derived from the Collection interface. Both kinds of collections interfaces are shown in Figure 10-1.

In a web application, you would like to test the web controllers developed with the Spring MVC framework.

Figure 10-1. The hierarchy of collection interfaces. Each child interface in this hierarchy extends the parent interface. The List and Set interfaces extend from the Collection interface, and there is no direct implementation of the Collection interface. The following list discusses some characteristics of the subinterfaces of Collection (that is, List and Set) and of Map: List: An ordered collection of data items; i.e. you know exactly where each item is in the list. A list can contain duplicate elements. ArrayList, LinkedList, and Vector are the classes that implement the List interface. Map: An object that maps keys to values: each key can map to at most one value. Maps cannot contain duplicate keys. HashMap and HashTable are examples of classes that implement the Map interface. No duplicate keys are allowed in maps; duplicate values are allowed. Set: A collection of unique items; i.e. there are no duplicates. HashSet and LinkedHashSet are examples of classes that implement the Set interface. To avoid confusion in terminology, remember the following points: Collection (with uppercase C) is the java.util.Collection interface. A collection (with lowercase c) refers to any implementation (that is, data structure) of a Collection interface such as Set or List. Collections is the java.util.Collections class, which offers a number of static utility methods that can be invoked on collections. When the text uses the term List, Map, or Set, you need to figure out from the context if it is talking about the interface or the objects of the class that implement the interface.

A Spring MVC controller is invoked by DispatcherServlet with an HTTP request object and an HTTP response object. After processing a request, the controller creates a ModelAndView object and returns it to DispatcherServlet for rendering the view. The main challenge of unit testing Spring MVC controllers, as well as web controllers in other web application frameworks, is simulating HTTP request objects and response objects in a unit testing environment. Fortunately, Spring supports web controller testing by providing a set of mock objects for the Servlet API (including MockHttpServletRequest, MockHttpServletResponse, and MockHttpSession). To test a Spring MVC controller s output, you need to check if the ModelAndView object returned to DispatcherServlet is correct. Spring also provides a set of assertion utilities for checking the contents of a ModelAndView object. Spring 2.5 supports annotation-based controllers, which don t need to extend a Spring MVC controller base class or deal with HTTP requests and responses directly. Therefore, they can be tested just like simple Java classes.
