Building RESTful Python Web Services

By: Gaston C. Hillar

Overview of this book

Python is the language of choice for millions of developers worldwide, due to its gentle learning curve as well as its vast applications in day-to-day programming. It serves the purpose of building great web services in the RESTful architecture. This book will show you the best tools you can use to build your own web services. Learn how to develop RESTful APIs using the popular Python frameworks and all the necessary stacks with Python, Django, Flask, and Tornado, combined with related libraries and tools. We will dive deep into each of these frameworks to build various web services, and will provide use cases and best practices on when to use a particular framework to get the best results. We will show you everything required to successfully develop RESTful APIs with the four frameworks such as request handling, URL mapping, serialization, validation, authentication, authorization, versioning, ORMs, databases, custom code for models and views, and asynchronous callbacks. At the end of each framework, we will add authentication and security to the RESTful APIs and prepare tests for it. By the end of the book, you will have a deep understanding of the stacks needed to build RESTful web services.

Preface

Setting up unit tests


We will use nose2 to make it easier to discover and run unit tests. We will measure test coverage, and therefore, we will install the necessary package to allow us to run coverage with nose2. First, we will install the nose2 and cov-core packages in our virtual environment. The cov-core package will allow us to measure test coverage with nose2.

Make sure you quit the Tornado's HTTP server. Remember that you just need to press Ctrl + C in the Terminal or command-prompt window in which it is running. We just need to run the following command to install the nose2 package that will also install the six dependency:

pip install nose2

The last lines for the output will indicate that the nose2 package has been successfully installed:

    
    Collecting nose2
    Collecting six>=1.1 (from nose2)
      Downloading six-1.10.0-py2.py3-none-any.whl
    Installing collected packages: six, nose2
    Successfully installed nose2-0.6.5 six-1.10.0

We just need to run the following...
