Listing 10-6. A Pygame Jukebox (jukebox.py) SCREEN_SIZE = (800, 600) # Location of music on your computer MUSIC_PATH = "./MUSIC" import pygame from pygame.locals import * from math import sqrt import os import os.path def get_music(path): # Get the filenames in a folder raw_filenames = os.listdir(path) music_files = [] for filename in raw_filenames: # We only want ogg files if filename.endswith('.ogg'): music_files.append(os.path.join(MUSIC_PATH, filename)) return sorted(music_files)

The setup method follows the class declaration. It is indicated by the [SetUp] attribute above the method signature. When NUnit sees this method, it will run whatever code is inside it before running every test case defined elsewhere in the test class. The setup method is very handy when you need a known state of data defined before each test case is run. There should never be more than one setup method in a test class. Listing 7-1 defines a Flight object that has a flight number of 4332, a departure airport of "DEN", an arrival airport of "IAH", and that the flight seats 80 passengers.

The preceding example creates an array of two Windows control objects, upcasting them to their base class, Control. Next, it binds the first control to the control identifier; downcasts this to its specific type, Button; and adds a handler to its DoubleClick event, an event not available on the Control class.

class Button(object): def __init__(self, image_filename, position): self.position = position self.image = pygame.image.load(image_filename) def render(self, surface): # Render at the center x, y = self.position w, h = self.image.get_size() x -= w /2 y -= h / 2 surface.blit(self.image, (x, y))

Closely related to casting is the idea of type tests. You can bind an identifier to an object of a derived type, as you did earlier when you bound a string to an identifier of type obj: let myObject = ("This is a string" :> obj) You can bind an identifier to an object of a derived type, so it is often useful to be able to test what this type is. To do this, F# provides a type-test operator, which consists of a colon followed by a question mark (: ). To compile, the operator and its operands must be surrounded by parentheses. If the identifier in the type test is of the specified type or a type derived from it, the operator returns true; otherwise, it returns false. The next example shows two type tests, one that returns true and another that returns false: let anotherObject = ("This is a string" :> obj) if (anotherObject : string) then printfn "This object is a string" else printfn "This object is not a string" if (anotherObject : string[]) then printfn "This object is a string array" else printfn "This object is not a string array" First you create an identifier, anotherObject, of type obj, binding it to a string. Then you test whether the anotherObject is a string, which returns true. Next, you test whether it is a string array, which, of course, returns false.

The opposite of the setup method is the teardown method. This is indicated by a method with the [TearDown] attribute above it. The teardown method will be called after each test case is run. This allows you to reset the system back to a known state before another test case is run. There should never be more than one teardown method in a test class. In Listing 7-1, the teardown method simply sets the Flight object to null so that it can be disposed of when the system needs to reclaim memory.
