The Spring framework provides a small suite of standard mock objects to aid in the creation of unit tests. Tools such as EasyMock are adequate for the creation of basic unit tests, but the Spring standard mock classes can make some tests less verbose, while allowing for more-sophisticated test behavior. Table 10-1 enumerates the standard mock object implementations provided with the Spring framework.

parameter. This ratio is needed because the pixels are not squared (normally they are more tall than wide), so a sphere can appear like an egg if the aspect ratio is not correctly defined. A concept closely related to the aspect ratio is the viewport, which is the portion of the 3D scene that will be drawn when rendering the scene. Because the viewport is a property of the device, in XNA, the aspect ratio is usually defined as device. Viewport.Width / device.Viewport.Height.

Matrix.CreateOrthographic: Creates a matrix used in orthogonal, or orthographic, projection. This method receives the width, height, and near and far planes that define the orthographic projection, and has a similar method named CreateOrthographicOffCenter, which creates the orthogonal projection matrix where the center of the 3D scene does not map to the center of the screen. You ll see the use of some of these functions in this chapter s sample code, and others in the next chapters, where you ll create a complete 3D game.

Can be substituted for the JndiTemplate helper class in applications that use JndiTemplate instances to access JNDI. Provides a simple JNDI context so code that looks up JNDI resources directly (without using JndiTemplate) can be provided with suitable mock objects. A substitute for the ExpressionEvaluator JSTL class when testing custom JSP tags. Used to provide the configuration parameters when testing Java EE filter implementations (avoids the need for a servlet container and a deployment descriptor). A mock version of the HttpServletRequest object supplied to servlets and JSPs (and to controller classes via the dispatcher). The counterpart of the MockHttpServletRequest, this is a mock version of the HttpServletResponse object supplied to servlets and JSPs. Used to provide a mock HttpSession object to web application components. Used to provide a mock multipart file-upload object to fake the results of a multipart form upload. Typically, this would be set into the MultipartFile attribute(s) of a form bean. Used to provide a mock request object to controllers expecting to receive multipart form uploads. This allows you to check that the multipart file is correctly bound to form properties or otherwise extracted from the request object correctly. Used to fake the PageContext object when testing custom JSP tags. Used to supply configuration parameters to servlets under test (avoids the need for a servlet container and a deployment descriptor).

Lights, Camera . . . Effects!

This suite of tests is heavily oriented toward the testing of the presentation components because these are the classes that are likely to have the heaviest dependency on the normal Java EE way of doing things. For example, it is often desirable to configure a Java EE application by using JNDI resources. Because this is a process of dependency lookup, legacy code will be difficult to inject with the resource, but the SimpleNamingContext mock class can be used in a stand-alone environment to supply appropriate mock substitutes for the real resources being looked up.
