final String content = (String)message.getContent(); assertTrue( content.contains("User username has updated one of their timesheets.")); } Although this test is complicated by the need to configure a Velocity engine and provide this to the implementation, the test takes the same form. We treat the Velocity engine as infrastructure that can be assumed reliable. Because it is easier to use the real thing than create a mock object, we do so. The test is also made slightly more complicated by the need to extract the sender, recipient, subject, and content details from the MimeMessage. Rather than try to parse the HTML generated by the default Velocity template that we are using, or to rewrite the template itself, we treat the message as a string and check that it contains the desired text somewhere. This does not absolutely test the message contents for correctness (the HTML might be malformed, causing the text to be hidden from the recipient), but is sufficient for our purposes. Unit tests cannot test everything; we would add a more detailed test only if later problems with the HTML content suggested that the additional effort was worthwhile. Listing 10-22 shows the test for the third implementation of the EmailDao that incorporates attachments into the message body.

Along with the vertices position and additional data, when creating 3D objects, you also need to specify how XNA will connect these vertices, according to different drawing primitives.

Note Drawing primitives are one of the three basic geometric primitives (points, lines, and triangles) used

public void testVelocityImageMailDao() throws Exception { final VelocityEngineFactoryBean factory = new VelocityEngineFactoryBean(); final Properties props = new Properties(); props.setProperty("resource.loader", "class"); props.setProperty("class.resource.loader.class", "org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader"); factory.setVelocityProperties(props); factory.afterPropertiesSet(); final VelocityEngine engine = (VelocityEngine)factory.getObject(); final VelocityImageMailDaoImpl impl = new VelocityImageMailDaoImpl(); impl.setFromAddress(FROM); impl.setRcptAddress(TO); impl.setSubject(SUBJECT); impl.setVelocityEngine(engine);

by XNA to render a collection of vertices. Depending on the primitive type chosen, the same set of vertices (known as the vertex buffer or vertex stream) will be rendered differently.

impl.setVelocityMacroPath("velocity/timesheet/attachments.vm"); impl.setMailSender(mailSender); final ClassPathResource image = new ClassPathResource("strawberry.jpg"); impl.setImage(image); impl.setAttachment(image); impl.sendTimesheetUpdate(timesheet); assertEquals(1,mailSender.getMessageCount()); final List<Message> messages = mailSender.getMimeMessages(); assertEquals(1,messages.size()); final MimeMessage message = (MimeMessage)messages.get(0); final Address[] senders = message.getFrom(); assertEquals(1,senders.length); final InternetAddress from = (InternetAddress)senders[0]; assertEquals(FROM,from.getAddress()); final Address[] recipients = message.getAllRecipients(); assertEquals(1,recipients.length); final InternetAddress to = (InternetAddress)recipients[0]; assertEquals(TO,to.getAddress()); final String subject = message.getSubject(); assertEquals(SUBJECT,subject); boolean messageTextSent = false; boolean messageInlineImageSent = false; boolean messageAttachmentSent = false; final MimeMultipart multipart = (MimeMultipart)message.getContent(); for(int i=0; i< multipart.getCount();i++) { final MimeBodyPart part = (MimeBodyPart)multipart.getBodyPart(i); if( partType(part,"multipart/related")) { final MimeMultipart mm = (MimeMultipart)part.getDataHandler().getContent();

The triangle is used as a base to create any other 2D or 3D objects. This is because a primitive defined with only three points is guaranteed to be in a single plane and to be convex. (A line connecting any two points inside a triangle is always fully inside the triangle, which doesn t happen in some figures with four vertices.) These characteristics are the key to performing the fastest rendering possible by the graphics cards, which always use triangles as the base rendering primitives. So, for example, if you want to draw a square on the screen, you ll use two triangles. If you want to create a cube, you ll use 12 triangles (2 for each facet), as shown in Figure 8-4.

for(int j = 0; j < mm.getCount(); j++) { final BodyPart bp = mm.getBodyPart(j); if( partType(bp,"text/html")) { messageTextSent = true; } else if( partType(bp,"image/jpeg")) { messageInlineImageSent = true; } } } else if( partType(part,"image/jpeg")) { messageAttachmentSent = true; } } assertTrue(messageTextSent); assertTrue(messageInlineImageSent); assertTrue(messageAttachmentSent); } Here the complexity of extracting and verifying image data is severe enough that I have settled for checking that the expected components of the message are present though they may be corrupted. Again, we will make the test more complex only if we have reason to believe that there is a problem with the transmitted content. For now, we presume that the external libraries operate as specified. As you have now seen, the creation of mock objects can itself be a moderately complicated procedure. Sometimes it is unavoidable. For many cases, however, there are simpler options. We can generate mock implementations automatically, or we can use mock implementations provided with the libraries. In the next couple of sections, you will see both of these approaches.

Figure 8-4. A cube made with triangles In XNA, the graphics device object has a method named DrawPrimitives that is used to draw a vertex buffer according to a specific primitive type, defined by the PrimitiveType enumeration:

The service layer usually provides a thin veneer of functionality between the presentation layer and the various DAO implementations. There may be additional business logic, but its outputs are based purely on parameters passed in and obtained from calls to DAO methods. Listing 10-23 shows part of our implementation of the UserAccountService interface.

PointList: Each vertex is rendered isolated from the others, so you can see a list of floating points. Figure 8-5 presents a set of vertices rendered as a point list.
