Why CI/CD matters for development velocity in Jenkins - Quick Recap

Recall & Review

beginner

What does CI/CD stand for in software development?

CI/CD stands for Continuous Integration and Continuous Delivery (or Continuous Deployment). It is a method to frequently merge code changes and automatically deliver them to production.

How does Continuous Integration (CI) improve development velocity?

CI helps developers merge code changes frequently, which reduces integration problems and allows faster detection of bugs, speeding up the development process.

What role does Jenkins play in CI/CD?

Jenkins is a tool that automates the building, testing, and deployment of code, making CI/CD pipelines easier to manage and faster to execute.

Why does automation in CI/CD reduce errors?

Automation runs tests and deployments consistently without human mistakes, ensuring code quality and faster feedback to developers.

How does CI/CD help teams deliver features faster?

By automating testing and deployment, CI/CD lets teams release small changes quickly and safely, reducing wait times and speeding up feature delivery.

What is the main benefit of Continuous Integration?

A Delaying code deployment

B Manual testing of code changes

C Frequent merging of code to detect bugs early

D Writing documentation

Continuous Integration focuses on merging code frequently to catch bugs early and reduce integration issues.

Which tool is commonly used to automate CI/CD pipelines?

A Jenkins

B Photoshop

C Excel

D Slack

Jenkins is a popular automation server used to build, test, and deploy code in CI/CD pipelines.

How does CI/CD improve development velocity?

A By automating testing and deployment

B By increasing manual code reviews

C By reducing code quality checks

D By delaying feedback to developers

Automation in CI/CD speeds up testing and deployment, allowing faster and safer code releases.

What does Continuous Delivery ensure?

A Code is never tested

B Code is always ready to be deployed

C Code is deployed manually every month

D Code is written without reviews

Continuous Delivery means the code is always in a deployable state, ready to be released at any time.

Why is early bug detection important in CI/CD?

A It delays the release process

B It increases the number of bugs

C It makes testing unnecessary

D It reduces the cost and time to fix issues

Finding bugs early helps fix them quickly and cheaply, improving development speed and quality.

Explain how CI/CD pipelines help teams deliver software faster and with fewer errors.

Think about how automation and frequent testing reduce manual work and mistakes.
