Azure Functions Unit/Integration Testing Sample

This repository contains a sample application to showcase how one can implement Unit and Integration testing for an Azure Functions application.
Its essentially a companion for my series of blog posts on Test Driven Development of Serverless Apps with Azure Functions, which can be accessed at this link.

Getting Started

1. Clone this repo: git clone https://github.com/sntnupl/azure-functions-sample-unittest-integrationtest
2. Open SampleApp.sln in Visual Studio.
3. Build the solution
4. Create a file titled local.settings.json in InvoiceProcessor project.
   • A sample file titled sample.local.settings.json is provided, you can use this file to create the above. Remember to replace the <PLACEHOLDER> with actual values though.
5. Create a file titled appsettings.json in InvoiceProcessor.Tests.Integration project.
   • Again, a sample file titled sample.appsettings.json is provided, you can use this file to create the above and remember to replace the <PLACEHOLDER> as before.
6. Run all tests in the solution (using the Visual Studio test explorer).

Pre-requisites

• Follow official document by Microsoft on Getting Started with Azure Functions to get your development setup ready.
• I personally used Visual Studio IDE to develop and test this application, Quickstart: Create your first function in Azure using Visual Studio is a nice step-by-step guide for the same.
