The test metadata allows defining an exception attribute and makes it possible to test exceptions. The way it works is that the test method with the expected attributes points to the error message you expect, and the test will pass when the exception is raised. The following example demonstrates the expected attribute of the Test metadata. The rangeCheck method creates a new Sprite object. The code will produce a successful test because the child at index 1 does not exist, and thus the code causes an exception during runtime.

As you might expect, Hugh and I have a long list of follow-on projects to investigate when we get the time and one of them is to take Tutorial D and extend it to become what you might call Industrial D When it s defined, we would certainly like to see Industrial D (which by that time will probably be given some fancier name) to be implemented in commercial form That s definitely one of our goals..

Looking at the default cube object in Camera view, you see a pink outline around the edges furthest away from you. This shows that the object is already selected. To the right of the View menu on Blender s lower toolbar, click the Select menu and choose Select/Deselect All; the pink outline around the cube disappears. Blender offers a number of different methods for selecting objects in the 3D scene try Select Select All by Type Mesh. Because you have only one mesh object at the moment, which is the default cube, only one object is selected with this command. By contrast, if you use the Select Select/Deselect All toggle again, and switch back to Top view on the View menu, both the camera and light source are selected (outlined in pink) as well as the cube (see Figure 6-6). This global selection means that any transformation tools used on the cube affect the position of the camera and light source, too.

[Test(expected="RangeError")] public function rangeCheck():void { var child:Sprite = new Sprite(); child.getChildAt(0); }

You say some fairly harsh things about SQL. What are the major flaws Do you think SQL has a future or do you think it will be replaced by something closer to the relational model

Another example is expecting an assertion error. Take a look at the testAssertNullNotEqualsNull method. The method is expecting the AssertionFailedError fail error. The assertEquals method will succeed since null equals null, so the test will fail. Change the statement to the following:

Figure 6-6. The pink outer rectangle indicates that the camera and the object are selected. Note that the colored arrows have moved, too. In the Camera view, the selection of the camera is indicated by a pink outline around the largest rectangle in the window (because you can t see the camera itself in this view). Selecting multiple objects moves the colored arrows of the 3D Transform Manipulator tool away from the center of the cube. However, the crosshair cursor stays in the center of the cube, demonstrating that it s moved independently from the 3D Transform Manipulator. The crosshair 3D cursor indicates where new objects that you create will be placed. To relocate it, click anywhere on the plane. Right-clicking an individual object in Blender is supposed to select it, although this doesn t work on my laptop probably due to buggy 3D driver support in Ubuntu for the ATI graphics chip inside. (Rightclick selection does work on my desktop machine, which has a Matrox graphics card. If you re serious about working on a 3D project with Blender, you may need to invest in better hardware or, at the very least, a graphics card with decent 3D performance.) Instead, I use Blender s Lasso Select tool by holding down the Ctrl key, clicking and holding down the left mouse button, and drawing a shape around the object I want to select. The shape of the lasso is drawn on the screen as a thin gray line, which can be hard to see against the gray default plane (see Figure 6-7).
