DevOps Starter makes it easy to get started on Azure using either GitHub actions or Azure DevOps
I selected "DevOps Starter" in Azure Portal
I created a Node app
I selected Express
I selected Web App for Containers
I entered my GitHub credentials
I selected pricing tier "F1 Free"
Deployment to Azure was in progress
The GitHub Actions workflow ran Unit Tests
When Unit Tests passed, the Node app was deployed to Azure
Once deployed to Azure, Functional Tests (Selenium) ran
The GitHub Actions workflow completed
I reviewed the summary of Azure resources
I navigated to the production URL
I opened the repository with GitHub Desktop to add the Factorial API
I cloned the repository
I opened the project in Visual Studio Code
Run the updated app locally
BASH
1$ cd Application 2 3$ npm install haddley-factorial-cc 4# or 5$ npm install haddley-factorial-js 6 7$ npm install 8$ npm run start
I verified that the updated code returns factorial of 9
Run the unit tests locally
BASH
1$ cd ../Tests 2$ npm install 3$ gulp unittest
I ran the updated Unit Tests
Run the functional tests locally
BASH
1$ xattr -d com.apple.quarantine chromedriver 2 3$ npm run start& 4$ cd ../Tests 5$ gulp functionaltest --webAppUrl http://localhost:3000/
I ran the functional tests
I pushed updates to GitHub on origin master
The GitHub Actions workflow ran again
Test factorial API in production
The Factorial API was running in production
