Overview of this book

Python is a multi-domain, interpreted programming language. It is a widely used general-purpose, high-level programming language. It is often used as a scripting language because of its forgiving syntax and compatibility with a wide variety of different eco-systems. Python GUI Programming Cookbook follows a task-based approach to help you create beautiful and very effective GUIs with the least amount of code necessary. This book will guide you through the very basics of creating a fully functional GUI in Python with only a few lines of code. Each and every recipe adds more widgets to the GUIs we are creating. While the cookbook recipes all stand on their own, there is a common theme running through all of them. As our GUIs keep expanding, using more and more widgets, we start to talk to networks, databases, and graphical libraries that greatly enhance our GUI’s functionality. This book is what you need to expand your knowledge on the subject of GUIs, and make sure you’re not missing out in the long run.

Creating robust GUIs using unit tests


Python comes with a built-in unit testing framework and, in this recipe, we will start using this framework to test our Python GUI code.

Before we start writing unit tests, we want to design our testing strategy. We could easily intermix the unit tests with the code they are testing but a better strategy is to separate the application code from the unit test code.

Note

PyUnit has been designed according to the principles of all the other xUnit testing Frameworks.

Getting ready

We will test the internationalized GUI we created earlier in this chapter.

How to do it…

In order to use Python's built-in unit testing framework, we have to import the Python unittest module. Let's create a new module and name it UnitTests.py.

We first import the unittest module, then we create our own class and, within this class, we inherit and extend the unittest.TestCase class.

The simplest code to do it looks as follows:

import unittest 

class GuiUnitTests(unittest.TestCase): 
  ...
