We can now add the handle() method to BookDetailsController: protected ModelAndView handle( HttpServletRequest request, HttpServletResponse response, Object command, BindException errors) throws Exception { return null; } Initially it just returns null, because we want to be able to run the test first and see it fail cataclysmically (Well, perhaps not completely cataclysmically, but a simple test failed would be nice) Unfortunately, the testPageDisplayed() test code won t compile as it stands, because the handle() method on BookDetailsController is, rather annoyingly, protected not public (it overrides a Spring method) So we would need to make the overriding method public (in Java, it s legal to increase an overriding method s visibility) But another problem is that the handle() method accepts several objects that are difficult to create outside their respective APIs without a lot of boilerplate code.

There does not appear to be an easy way to find out your screen density in a similar fashion. If you absolutely need to know that, a hack would be to create res/valuesldpi/, res/values-mdpi/, and res/values-hdpi/ directories in your project, and add a strings.xml file to each. Put a string resource in strings.xml that has a common name across all three resource sets and has a distinctive value (e.g., name it density, with

The final step is to provide a way for the user to add new items. The easiest way to make this possible is to use a rich data control that deals with individual records either the DetailsView or the FormsView. The DetailsView is the simpler of the two, because it doesn t require a template. It s the one used in the following example. Ideally, you d define the DetailsView using a tag like this and let it generate all the fields it needs based on the bound data source:

Unfortunately, this won t work in this example. The problem is that this approach creates too many fields. In this example, you don t want the user to specify the item ID (that s set by the database automatically) or the category ID (that s based on the currently selected category). So neither of these details should appear. The only way to make sure this is the case is to turn off automatic field generation and define each field you want explicitly, as shown here:

<asp:DetailsView ID="DetailsView1" runat="server" DataSourceID="sourceItems" AutoGenerateRows="False"> <Fields> <asp:BoundField DataField="Title" HeaderText="Title" /> <asp:BoundField DataField="Price" HeaderText="Price"/> <asp:BoundField DataField="Description" HeaderText="Description" /> </Fields> </asp:DetailsView>

This is one of those wrinkles in the fabric of the otherwise perfect space-time continuum that surfaces to taunt us from time to time One solution is to pass null values into the method, but the method is now starting to look and behave less and less like it should in the real world, all for the purposes of testing For now, because we can, we ll leave handle() unaltered and with protected visibility, and instead add a separate, public method to BookDetailsController so that the test can call it We ll prefix the method with test so that later we ll know that it is for a unit test: public ModelAndView testHandle(Book command) throws Exception { return handle(null, null, command, null); } The new method simply delegates to the real handle() method.

values of ldpi, mdpi, and hdpi, respectively). Then test the value of the string resource at runtime. This is inelegant but should work.

You need to make a couple of other changes. To allow inserting, you need to set the AutoGenerateInsertButton to True. This way, the DetailsView creates the links that allow you to start entering a new record and then insert it. At the same time, you can set the DefaultMode property to Insert. This way, the DetailsView is always in insert mode and is used exclusively for adding records (not displaying them), much like the non-data-bound page shown earlier.

<asp:DetailsView ID="DetailsView1" runat="server" DefaultMode="Insert" AutoGenerateInsertButton="True" DataSourceID="sourceItems" AutoGenerateRows="False"> ... </asp:DetailsView>

handle() doesn t actually use the request, response, or errors parameter, so we can pass in null for these In fact, the only parameter that really matters is Book Now we can rewrite the test method to use this new method: ModelAndView modelAndView = bookDetailsControllertestHandle(command); Checking the sequence diagram in Figure 12-11, we can see that the second method, checkBookFound(), is actually a private method called by handle(), so we don t need to write a specific test method for it5 Instead, the output from checkBookFound() will contribute to the eventual output of handle(), which we do need to test Now we can compile the test, run it against BookDetailsController (with its empty handle() method that returns null), and watch it fail Hurrah sort of..

The ObjectDataSource provides the same type of support for updatable data binding as the SqlDataSource. The first step is to specify the UpdateMethod, which needs to be a public instance method in the same class:
