Python for Geeks

By: Muhammad Asif

Overview of this book

Python is a multipurpose language that can be used for multiple use cases. Python for Geeks will teach you how to advance in your career with the help of expert tips and tricks. You'll start by exploring the different ways of using Python optimally, both from the design and implementation point of view. Next, you'll understand the life cycle of a large-scale Python project. As you advance, you'll focus on different ways of creating an elegant design by modularizing a Python project and learn best practices and design patterns for using Python. You'll also discover how to scale out Python beyond a single thread and how to implement multiprocessing and multithreading in Python. In addition to this, you'll understand how you can not only use Python to deploy on a single machine but also use clusters in private as well as in public cloud computing environments. You'll then explore data processing techniques, focus on reusable, scalable data pipelines, and learn how to use these advanced techniques for network automation, serverless functions, and machine learning. Finally, you'll focus on strategizing web development design using the techniques and best practices covered in the book. By the end of this Python book, you'll be able to do some serious Python programming for large-scale complex projects.

Chapter 5: Testing and Automation with Python

Software testing is the process of validating an application or a program as per user requirements or desired specifications and evaluating the software for scalability and optimization goals. Validating software as a real user takes a long time and is not an efficient use of human resources. Moreover, testing is not performed only one or two times, but it is a continuous process as a part of software development. To rescue the situation, test automation is recommended for all sorts of testing. Test automation is a set of programs written to validate an application's behavior using different scenarios as input to these programs. For professional software development environments, it is a must that automation tests get executed every time the source code is updated (also called a commit operation) into a central repository.

In this chapter, we will study different approaches to automated testing, followed by looking at different...
