CI/CD pipeline setup in React Native - Cheat Sheet & Quick Revision

Recall & Review

beginner

What does CI stand for in CI/CD?

CI stands for Continuous Integration. It means automatically combining code changes from many developers into a shared main branch frequently.

beginner

What is the main goal of a CD pipeline?

CD stands for Continuous Delivery or Continuous Deployment. The goal is to automatically test and deliver code changes to users quickly and safely.

Name a common tool used to automate CI/CD pipelines for React Native apps.

Popular tools include GitHub Actions, CircleCI, and Bitrise. They help run tests, build apps, and deploy automatically.

beginner

Why is automated testing important in a CI/CD pipeline?

Automated tests catch bugs early before code reaches users. This keeps the app stable and saves time fixing problems later.

beginner

What is a build step in a CI/CD pipeline?

A build step compiles the React Native code into an app package that can run on devices or emulators.

What is the first step in a typical CI/CD pipeline?

A Deploy to production

B Code commit to the repository

C Run automated tests

D Build the app

The pipeline usually starts when code is committed to the repository, triggering the next steps.

Which tool can be used to automate React Native CI/CD pipelines?

A Bitrise

B Photoshop

C Excel

D Slack

Bitrise is a popular CI/CD tool for mobile apps including React Native.

Why do we run tests automatically in CI/CD?

A To find bugs early

B To slow down development

C To avoid writing code

D To increase manual work

Automated tests help find bugs early and keep the app stable.

What does the build step produce in a React Native CI/CD pipeline?

A A text document

B A design mockup

C A database backup

D An app package ready to install

The build step creates an app package that can be installed on devices.

Continuous Deployment means:

A Never releasing code

B Manually approving every release

C Automatically releasing code to users after tests pass

D Only testing code locally

Continuous Deployment automatically releases code to users once it passes tests.

Explain the main steps involved in setting up a CI/CD pipeline for a React Native app.

Think about what happens from code change to app delivery.

Why is automation important in CI/CD pipelines?

Consider benefits of using machines to do repetitive tasks.
