Azure Functions Node.js E2E Tests

This repo contains end-to-end tests for Node.js on Azure Functions. These are automated tests designed to run regularly against prerelease versions of all the various pieces that make up the Node.js experience on Azure Functions, including:

• Azure Functions Host
• Azure Functions Core Tools
• Node.js Worker
• Node.js Library

Pipeline

Here is the general flow of the pipeline:

1. Install node modules and build both the tests themselves and the test apps
2. Create several resources in Azure that will be used for testing different bindings. A unique resource prefix is generated for each individual build so that builds aren't sharing resources
3. Run the tests. A few notes:
   1. These are run in parallel by OS, but in serial by Node.js version and programming model version. Theoretically every combination could be run in parallel, but that would use a ton of Azure Pipelines agents and create a lot of Azure resources for minimal gain in time.
   2. The primary method of validation is to run core tools against the test app and validate the output
4. Delete the Azure resources
5. Upload test results

Running locally

Install core tools

1. Run ./scripts/install-func-cli.ps1 in PowerShell to install the latest nightly build of Azure Functions Core Tools

Build

1. Run npm run install and npm run build in the root directory, and in the test app folders (app/v3 and app/v4)

Create resources

You need to create resources once in your subscription, but then you can reuse the same resources for many different test runs. The CI pipeline will create and delete resources each time, but you don't need to do that.

1. Set the environment variable BUILD_BUILDNUMBER to any number like 20230520.1. You want it to be reasonably unique because this will be used as a prefix for your Azure resources.
2. Run az login and az account set -s <subscription id> if you're not already logged in to the Azure CLI. The tests will use these credentials.
3. Run npm run createResources
4. Validate the resources were created. You should see a resource group in your subscription like e2edarwin202305201group with several resources

Run tests

1. Run npm run testV3 to test the v3 app, npm run testV4 to test the v4 app, or npm run test to test both
