Echo Quick Start Guide

By: Ben Huson

Overview of this book

Echo is a leading framework for creating web applications with the Go language.  This book will show you how to develop scalable real-world web apps, RESTful services, and backend systems with Echo.  After a thorough understanding of the basics, you'll be introduced to all the concepts for a building real-world web system with Echo. You will start with the the Go HTTP standard library, and setting up your work environment. You will move on to Echo handlers, group routing, data binding, and middleware processing. After that, you will learn how to test your Go application and use templates.  By the end of this book you will be able to build your very own high performance apps using Echo. A Quick Start Guide is a focussed, shorter title which provides a faster paced introduction to a technology. They are for people who don’t need all the detail at this point in their learning curve. The presentation has been streamlined to concentrate on the things you really need to know, rather than everything.

Summary

As you can see, testing can be quite involved, and overwhelming to a developer, but it is currently, with the exception of formal method modeling, the only way to be sure your code is doing what you say it is doing. Empirical analysis on instrumented code can show you each and every line in your code that is “covered” by a test. This coverage information is good and bad. It is good because you have a number which marches forward or backward that you can use as a gauge of how much quality your code has within. It is bad because, just like any other gauge, developers can tweak the coverage numbers without actually increasing quality. By merely running code within the testing framework, the coverage number will increase but if your tests do not have valid assertions and are looking for the right things, the test is bunk. A pragmatic and honest approach to testing...
