Testing

All code is guilty,until proven innocent

Testing

CI is a software development practice in which you

build and test software every time a developer

pushes code to the application.

Continuous Integration

Continuous Integration [CI]

CI = TEST + BUILD

Continuous Integration

Is an approach in which automated testing and

deployment capabilities allow rapid deployments.

With minimal human intervention: triggers.

Continuous Delivery

Continuous Delivery

Continuous Delivery =

TEST + BUILD + → DEPLOY👆

Continuous Delivery

Continuous Delivery =

(TEST + BUILD) + → DEPLOY👆

Continuous Delivery

Continuous Delivery =

(CI) + → DEPLOY👆

Continuous Delivery

Every code change goes through a pipeline and is put

into production automatically. There's no human

intervention at all.

Continuous Deployment

Continuous Deployment [CD]

CD =

TEST + BUILD + ⚙ → DEPLOY

Continuous Deployment

🚢 Ship the code within a merge request 🔄 Run automated tests 🔐 Build and deploy to a staging environment 👀 Preview the changes

🔎 Review the code and merge into master 👆 Deploy your changes to a production environment

😭 Rollback if something goes wrong

Flow: staging
