Overview of this book

With the over-abundance of tools in the JavaScript ecosystem, it's easy to feel lost. Build tools, package managers, loaders, bundlers, linters, compilers, transpilers, typecheckers - how do you make sense of it all? In this book, we will build a simple API and React application from scratch. We begin by setting up our development environment using Git, yarn, Babel, and ESLint. Then, we will use Express, Elasticsearch and JSON Web Tokens (JWTs) to build a stateless API service. For the front-end, we will use React, Redux, and Webpack. A central theme in the book is maintaining code quality. As such, we will enforce a Test-Driven Development (TDD) process using Selenium, Cucumber, Mocha, Sinon, and Istanbul. As we progress through the book, the focus will shift towards automation and infrastructure. You will learn to work with Continuous Integration (CI) servers like Jenkins, deploying services inside Docker containers, and run them on Kubernetes. By following this book, you would gain the skills needed to build robust, production-ready applications.

Understanding different types of test


First, let's learn about the different types of tests and how they all fit into our project's workflow. The first thing to note is that some tests are more technically-focused, while others are more business-focused; some tests are only concerned with a very small part of the whole system, while others test the system as a whole. Here's a brief overview of the most common types of tests you'll encounter:

  • Unit tests: These test the smallest testable parts of an application, called units. For example, if we have a function called createUser, we can write a unit test that tests that the function always returns a promise. With unit tests, we are only concerned with the function of the unit, independent of external dependencies. If the unit has external dependencies, such as a database, we must substitute the real database client with a fake one. This fake client must be able to mimic the behavior of the database adequately so that, from the perspective of...
