Django 1.1 Testing and Debugging. Building rigorously tested and bug-free Django applications

Karen M. Tracey, Karen Tracey, Jacob Kaplan-Moss

Bugs are a time consuming burden during software development. Django's built-in test framework and debugging support help lessen this burden. This book will teach you quick and efficient techniques for using Django and Python tools to eradicate bugs and ensure your Django application works correctly. This book will walk you step by step through development of a complete sample Django application. You will learn how best to test and debug models, views, URL configuration, templates, and template tags. This book will help you integrate with and make use of the rich external environment of test and debugging tools for Python and Django applications. The book starts with a basic overview of testing. It will highlight areas to look out for while testing. You will learn about different kinds of tests available, and the pros and cons of each, and also details of test extensions provided by Django that simplify the task of testing Django applications. You will see an illustration of how external tools that provide even more sophisticated testing features can be integrated into Django's framework. On the debugging front, the book illustrates how to interpret the extensive debugging information provided by Django's debug error pages, and how to utilize logging and other external tools to learn what code is doing.

Nest.js: A Progressive Node.js Framework. Hit the ground running with Nest.js

Greg Magolan, Patrick Housley, Adrien de Peretti, Jay Bell, ...

Nest.js is a modern web framework built on a Node.js Express server. With the knowledge of how to use this framework, you can give your applications an organized codebase and a well-defined structure.The book begins by showing how to use Nest.js controllers, providers, modules, bootstrapping, and middleware in your applications. You’ll learn to use the authentication feature of Node.js to manage the restriction access in your application, and how to leverage the Dependency Injection pattern to speed up your application development. As you advance through the book, you'll also see how Nest.js uses TypeORM—an Object Relational Mapping (ORM) that works with several relational databases. You’ll use Nest.js microservices to extract part of your application’s business logic and execute it within a separate Nest.js context. Toward the end of the book, you’ll learn to write tests (both unit tests as well as end-to-end ones) and how to check the percentage of the code your tests cover.By the end of this book, you’ll have all the knowledge you need to build your own Nest.js applications.
