What is Continuous Integration and why is it important?

Continuous Integration (CI) is a software development practice where code changes are automatically tested and merged into a shared repository. It's important because it helps catch bugs early, improves collaboration, and ensures that the software is always in a deployable state.

How does CI work in a typical development workflow?

In a typical workflow, developers push their code changes to a version control system. CI tools automatically run tests on these changes, and if everything passes, the code is merged into the main branch. This process helps maintain code quality and reduces integration issues.

What tools are commonly used for CI?

Some popular CI tools include Jenkins, Travis CI, CircleCI, and GitHub Actions. Each has its own features and integrations to support various development environments.

Can you explain the benefits of using CI?

Certainly! The benefits of CI include faster feedback on code changes, reduced integration problems, improved collaboration among team members, and a more reliable release process.

What are some best practices for implementing CI?

Best practices for CI include maintaining a single source of truth, running tests on every commit, keeping builds fast, and ensuring that the CI environment mirrors production as closely as possible.
