This subfolder is the source code for the How to Test Azure SDK Integration in JavaScript Applications. The purpose is to demonstrate unit test mocks for the Azure SDK for JavaScript. These specific examples use Azure Cosmos DB.

Use Azure CLI to create Cosmos DB resource if you intend to insert a document with the application code against the cloud resource. Script

1. npm install

2. npm test
