Truffle Quick Start Guide

By: Nikhil Bhaskar

Overview of this book

Truffle is a world-class development environment, testing framework and asset pipeline for Ethereum, aiming to make life as an Ethereum developer easier. If you are a web developer wanting to try your hand at developing Dapps with Truffle, then this is the book for you. This book will teach you to write smart contracts and build Dapps with Truffle. You will begin with covering the basics of Truffle, briefly explaining how it integrates Solidity and Web3, in orderto start building a mini decentralized application. Also, you will dive into migration, testing and integrating Truffle with the use of popular JavaScript frameworks. Lastly, you will ship your decentralized application and package it into a product. Moreover, you will go through the best practices in Truffle,so as to increase your proficiency in building Dapps with Truffle. By the end of the book, you will be able to write smart contracts and build decentralized applications with Truffle on Ethereum blockchains.

Writing unit tests with Solidity

Before we start the exercises in this chapter, let's do the usual housekeeping:

  • Inside your truffle-practice folder, create a new folder called chapter6

Great! That's it. Let's get started with this chapter. Now, we've already built a few mini applications, so which one should we write tests for? Let's write tests for the mini-application we wrote in Chapter 1, Truffle for Decentralized Applications. Why? There are two reasons:

  • The Chapter 1, Truffle for Decentralized Applications, project contains fundamental Solidity elements that we should write tests for.
  • The Chapter 1, Truffle for Decentralized Applications, project does not rely on a particular JavaScript framework. Since it's in VanillaJS, you can just focus on writing unit tests without worrying about framework-specific caveats.

Since we are writing tests...
