Python GUI Programming Cookbook, Second Edition - Second Edition

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.

How to write unit tests using the Eclipse PyDev IDE

In the previous recipe, we started using Python's unit testing capabilities, and in this recipe, we will ensure the quality of our GUI code by further using this capability.

We will unit test our GUI in order to make sure that the internationalized strings our GUI displays are as expected.

In the previous recipe, we encountered some bugs in our unit testing code but, typically, our unit tests will find regression bugs that are caused by modifying the existing application code, not the unit test code. Once we have verified that our unit testing code is correct, we do not usually change it.


Our unit tests also serve as a documentation of what we expect our code to do.

By default, Python's unit tests are executed with a textual unit test runner, and we can run this in the PyDev plugin from within the Eclipse IDE. We can also run the very same unit tests from a console window.

In addition to the text runner in this recipe, we will explore PyDev...
