Continuous Integration, Delivery, and Deployment

By: Sander Rossel

Overview of this book

The challenge faced by many teams while implementing Continuous Deployment is that it requires the use of many tools and processes that all work together. Learning and implementing all these tools (correctly) takes a lot of time and effort, leading people to wonder whether it's really worth it. This book sets up a project to show you the different steps, processes, and tools in Continuous Deployment and the actual problems they solve. We start by introducing Continuous Integration (CI), deployment, and delivery as well as providing an overview of the tools used in CI. You'll then create a web app and see how Git can be used in a CI environment. Moving on, you'll explore unit testing using Jasmine and browser testing using Karma and Selenium for your app. You'll also find out how to automate tasks using Gulp and Jenkins. Next, you'll get acquainted with database integration for different platforms, such as MongoDB and PostgreSQL. Finally, you'll set up different Jenkins jobs to integrate with Node.js and C# projects, and Jenkins pipelines to make branching easier. By the end of the book, you'll have implemented Continuous Delivery and deployment from scratch.

End-To-End testing with Selenium

The next thing we are going to do is End-To-End (E2E) testing using our browser-our actual browser, as if it was operated by a human, but fully automated. The popular web UI test framework Selenium (http://www.seleniumhq.org/) will do this for you. As you can imagine, this is no easy task. Selenium needs to interface with different browsers, different languages, and different frameworks and it is all set up so future browsers, languages, and frameworks can be implemented. As such, it can be a bit of a pain to set up. There are a few moving parts you need to install, either on your computer or in your project, and to make things more complicated, those parts have different versions with different names. Don't panic though: throughout the remainder of this chapter, all will be revealed.

Selenium has its own language, Selenese, in which you can...
