Crafting Test-Driven Software with Python

By: Alessandro Molina

Overview of this book

Test-driven development (TDD) is a set of best practices that helps developers to build more scalable software and is used to increase the robustness of software by using automatic tests. This book shows you how to apply TDD practices effectively in Python projects. You’ll begin by learning about built-in unit tests and Mocks before covering rich frameworks like PyTest and web-based libraries such as WebTest and Robot Framework, discovering how Python allows you to embrace all modern testing practices with ease. Moving on, you’ll find out how to design tests and balance them with new feature development and learn how to create a complete test suite with PyTest. The book helps you adopt a hands-on approach to implementing TDD and associated methodologies that will have you up and running and make you more productive in no time. With the help of step-by-step explanations of essential concepts and practical examples, you’ll explore automatic tests and TDD best practices and get to grips with the methodologies and tools available in Python for creating effective and robust applications. By the end of this Python book, you will be able to write reliable test suites in Python to ensure the long-term resilience of your application using the range of libraries offered by Python for testing and development.

Introducing the Robot Framework

The Robot Framework is an automation framework mostly used to create acceptance tests in the Acceptance Test Driven Development (ATDD) and Behavior Driven Development (BDD) styles. Tests are written in a custom, natural English-like language that can be easily extended in Python, so Robot can, in theory, be used to write any kind of acceptance tests in a format that can be shared with other stakeholders, pretty much like what we have seen we can do with pytest-bdd in previous chapters.

The primary difference is that Robot is not based on PyTest, it is a replacement for PyTest, and is widely used to create end-to-end tests for mobile and web applications. For mobile applications, the Appium library allows us to write Robot Framework tests that control mobile applications on a real device, while the Selenium library provides a complete integration with web browsers, which means that the Robot Framework allows us to write tests that drive a real web browser...
