Continuous Integration, Delivery, and Deployment

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.

Gulp

You may have noticed, but our Gulp file fails to run. Basically, everything is well up to the tests of the minified JavaScript files. Luckily, we can fix this really easy! In the karma.min.conf.js file, simply make sure you browserify everything in the spec folder:

[...]
preprocessors: {
'../prod/scripts/*.js': ['browserify'],
'spec/*.js': ['browserify']
},
[...]

That should fix your Gulp run. Everything should work now, testing, linting, minifying, and so on. Another thing though, we have added the Node.js tests, which are not yet included in our gulpfile. We can simply create an extra task and run jasmine-node tests. Of course, we need an extra Karma plugin, the karma-jasmine-node plugin (https://www.npmjs.com/package/gulp-jasmine-node):

npm install karma-jasmine-node --save-dev

We can now add it to our gulpfile. It is...
