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.

Headless browser testing

There is just one problem we have not tackled yet. First, it is pretty annoying that you need to have all those browser windows open to test your code. Second, our server does not even have a user interface, so how is it going to open any browser? I will get back to the server issue later: even if we had a graphical interface, we would still have problems with IE, Edge, and Safari, so we need to tackle all of that. However, I am going to tackle that first issue right here.

While it is not necessarily a problem that we have multiple browser windows running, they come with a trade-off. First, of course, they take up space on your screen. You have to work around them, make sure you do not accidentally close any of them, and you should also not get too distracted by all the flashy test runs. Another issue with browsers is that it takes time to render your...
