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.

Testing the database

Now that we have this procedure we probably want to test it, just like we test our other code. Next to testing whether your SQL is in order, you can also test whether your schema is in order (does table product exist and does it have a price column, for example). This is something that is completely different from MongoDB as it did not have a schema. Testing databases can be a bit difficult. You need test data, maybe, inserted with some seed function, maybe, already present. You do not want to mess up your test data by making changes in your application. You probably need to set up database connections and transactions. It can be a hassle. However, there are some tools that make it a bit easier. pgTap is one of those tools. Using pgTap, you can write a test script in SQL, run it in a console, and output your data in TAP format (Test Anything Protocol, https...
