Developers looking to keep their JavaScript code bug-free will want to unit test using Jasmine, one of the most popular unit testing frameworks around. Any project of meaningful size should be automatically tested to help catch bugs as early as possible. Jasmine, a testing framework for JavaScript, makes it easy to test JavaScript projects, from browser-based applications to Node.js. While a quick understanding of Jasmine can be gleaned from the project’s homepage, the framework has a lot of details and exciting plugins. This book explores Jasmine in a depth that can’t be found elsewhere. This book provides: Exposure to some Jasmine plugins, to extend Jasmine and allow for more functionality and more thorough testing An Understanding of Jasmine’s main features, to allow code to be automatically tested and reduce bugs An Explanation of how to get Jasmine working in different environments (in the browser, in Node.js, through Rails, et cetera), to make Jasmine easier to work with

Strengthen your applications by adopting Test-Driven Development (TDD), the OpenAPI Specification, Continuous Integration (CI), and container orchestration. Key FeaturesCreate production-grade JavaScript applications from scratchBuild microservices and deploy them to a Docker container for scaling applicationsTest and deploy your code with confidence using Travis CIBook Description 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. What you will learnPractice Test-Driven Development (TDD) throughout the entire bookUse Cucumber, Mocha and Selenium to write E2E, integration, unit and UI testsBuild stateless APIs using Express and ElasticsearchDocument your API using OpenAPI and SwaggerBuild and bundle front-end applications using React, Redux and WebpackContainerize services using DockerDeploying scalable microservices using KubernetesWho this book is for If you're a JavaScript developer looking to expand your skillset and become a senior JavaScript developer by building production-ready web applications, then this book is for you.
