2.  CI/CD pipeline
 Continuously integrate
and release new features
 Continuous integration (CI)
 Write code, test and integrate it in the product
 Continuous delivery (CD)
 Continuously release new features

3.  GitHub Actions
 Cloud-based software workflow automation
environment (CI/CD on the GitHub cloud)
 Allows creating CI/CD pipelines to build, test and
deploy software projects, directly from a GitHub repo
 https://github.com/features/actions
 Free for public repos + 2000 mins / month
for private repos with the free plan

4.  Events execute workflows
(one or several jobs, running in parallel)
 Workflows hold jobs
(e. g. build, check security, deploy)
 Jobs hold steps (e. g. "checkout the
code", "install .NET", "run tests", …)
 Steps hold actions
(commands like `dotnet test`)

5.  We have a JS App (with integration tests):
 Code: https://github.com/nakov/MVC-app-integration-tests-example-mocha
 Live: https://nakov-mvc-node-app.herokuapp.com
Sample JS App: Students Registry

6.  Clone the app repo
 Restore the Node packages:
 Run the Mocha integration tests
Build and Run Locally (by Hand)
git clone https://github.com/nakov/MVC-app-integration-
tests-example-mocha
npm install
npm test

7.  Let's implement a CI/CD
pipeline in GitHub Actions
 Build & test workflow
 Runs on push
 Deploy workflow
 Runs manually
