Overview of this book

Microsoft provides a solution for easily running small segments of code in the cloud with Azure Functions. The second edition of Azure Serverless Computing Cookbook starts with intermediate-level recipes on serverless computing along with some use cases demonstrating the benefits and key features of Azure Functions. You’ll explore the core aspects of Azure Functions, such as the services it provides, how you can develop and write Azure Functions, and how to monitor and troubleshoot them. As you make your way through the chapters, you’ll get practical recipes on integrating DevOps with Azure Functions, and providing continuous integration and continuous deployment with Azure DevOps. This book also provides hands-on, step-by-step tutorials based on real-world serverless use cases to guide you through configuring and setting up your serverless environments with ease. You will also learn how to build solutions for complex, real-world, workflow-based scenarios quickly and with minimal code using Durable Functions. In the concluding chapters, you will ensure enterprise-level security within your serverless environment. The most common tips and tricks that you need to be aware of when working with Azure Functions on production environments will also be covered in this book. By the end of this book, you will have all the skills required for working with serverless code architecture, providing continuous delivery to your users.

Developing unit tests for Azure Functions with HTTP triggers

So far, we have created multiple Azure Functions and validated their functionality using different tools. The functionalities of the functions that we have developed so far is pretty simple and straightforward; however, in your real-world applications, it won't be that simple—there will likely be many changes to the code that we initially created. It's good practice to write automated unit tests that can help us in testing the functionality of our Azure Functions. Every time we run these automated unit tests, we can test all the various paths within the code.

In this recipe, we will learn how to use the basic HTTP trigger, and see how easy it is to write automated unit test cases for this using Visual Studio Test Explorer and Moq (an open source framework available as a NuGet package).
