As mentioned in the section about testing in 3, unit tests are used to test models. I ll show a few tests for ProductType and Product here, but as mentioned earlier there won t be space enough to test everything as it should be tested. First of all, there is only one interesting fact to test about ProductType: that name must be provided. So, open up the file test/unit/product_type_test.rb, remove the test_truth method, and add this method instead: def test_invalid_name p = ProductType.new assert !p.valid assert p.errors.invalid (:name) end This method first creates a new ProductType, and because you don t specify a name, it shouldn t be valid. The method assert, and all methods beginning with assert_, are used to check a certain invariant. In this method, you just check that the model object is not valid, and that the errors provided include at least one for name. There are more things to test for Product, though. First of all, go ahead and open the file test/unit/product_test.rb and remove the test_truth method. The next step demands a slight deviation into the territory of fixtures. A fixture is a YAML file that contains data for test fixtures, which means your tests will always use the same data, instead of relying on whatever can be found in the database at the moment. Because Products needs product types to work, you ll first change those fixtures. Open the file test/fixtures/product_types.yml and replace the contents with this: book: id: 1 name: Book music: id: 2 .net ean 13 reader . NET EAN - 13 Barcode Reader for C#, VB. NET , ASP.

Download .NET Barcode ... should see HelloAndroidApp running in the emulator, as shown in Figure 2-6. In addition, be aware that the emulator starts other applications in the background during the startup process, so you might see a warning or error message from time to time. If you see an error message, you can generally dismiss it to allow the emulator to go to the next step in the startup process. For example, if you run the emulator and see a message like application abc is not responding, you can either wait for the application to start or simply ask the emulator to forcefully close the application. Generally, you should wait and let the emulator start up cleanly if you have the patience. Caution The indentation here must be done with spaces, not tabs.

HelloAndroidApp running in the emulator Now you know how to create a new Android application and run it in the emulator. Next, we ll discuss the pieces that make the simple program display in the emulator. We ll begin by talking about an Android application s artifacts and structure. As you can see, it s a standard JSF button (<h:commandButton>) and, of course, not skinnable. You can add a style via the style or styleClass attribute that matches the current skin (ruby), but then you would need to adjust it each time you change the skin. A better way is to use skin parameters to add style to the button. For example, you can use tabBackgroundColor as the color for the button. Of course, you can use any other skin parameter from the skin. <h:commandButton action="next" value="Next page I want to learn about world oceans!" style="background-color:#{richSkin.tabBackgroundColor}"/> Although the size and complexity of Android applications can vary greatly, their structures will be similar. Figure 2-7 shows the structure of the Hello World! app you just built. .net ean 13 reader Packages matching ean-13 - NuGet Gallery

As you might notice, this is the same type as the migrations added, but adding them here means you can get at the objects much more easily later on. Next, you add two fixtures for Product by replacing the contents of the file test/fixtures/products.yml with this: first: id: 1 product_type_id: 1 name: Abc price: 1440 another: id: 2 product_type_id: 2 name: Cde price: 2990 Now you re almost ready to add some Product testing. You just need to tell Rails that it should use the fixtures for product types, in addition to the fixtures for Product. You can achieve this by adding this line after the corresponding line for products, in the file product_test.rb: fixtures :product_types The first test is the same as for product type, just checking that an invalid name can t get in: def test_invalid_name p = Product.new assert !p.valid assert p.errors.invalid (:name) end You do the exact same thing for type: def test_invalid_type p = Product.new assert !p.valid assert p.errors.invalid (:product_type) end Figure 2-7. The structure of the Hello World! app Android applications have some artifacts that are required and some that are optional. Table 2-1 summarizes the elements of an Android application. (Note that Android 1.5 adds a few elements; see 12 for details.) Table 2-1. The Artifacts of an Android Application .net ean 13 reader . NET Barcode Scanner SDK | How to Read EAN - 13 Barcode in .
