Continuous Integration

5 minutes 5 Questions

The practice of continuous integration is about frequently integrating code changes into a shared repository. Each change is then automatically built and tested to catch bugs as quickly as possible. Developers integrate their work frequently - usually each person integrates at least daily. With CI,…

Question 1

The development team needs to minimize the risk of conflicts that may arise from merging code in the Continuous Integration process. What method should the team use?

Assign a dedicated team member for merging Merge small changes frequently Perform code reviews before merging Merge changes at the beginning of each day Use a separate branch for each team member Merge changes at the end of each sprint

Correct Answer: Merge small changes frequently

Merging small changes frequently reduces the risk of conflicts by allowing developers to address integration problems in smaller increments, while alternative approaches may not notably decrease risks.

Question 2

Which of the following should not be a part of a typical Continuous Integration pipeline?

Automated integration tests Manual code review Automated deployment to testing environment Static code analysis Source code repository Automated unit testing

Correct Answer: Manual code review

Continuous Integration pipeline should consist of fully automated processes. Manual code reviews, while essential in development, are not part of the Continuous Integration pipeline itself.

Question 3

The development team of a software company is cautious about new code breaking the Continuous Integration (CI) build. They want to avoid integrating code that could potentially have conflicts with the existing codebase. What strategy could they use?

Switch to a different CI tool Commit code less frequently Perform manual code review before every commit Implement a pre-commit or pre-push hook to run tests

Correct Answer: Implement a pre-commit or pre-push hook to run tests

The development team of a software company is right to be cautious about breaking the Continuous Integration (CI) build. The most useful strategy in this case is to 'Implement a pre-commit or pre-push hook to run tests'. This allows the team to identify potential conflicts before the new code is merged into the existing codebase. Such a process helps in ensuring that the new code is flawless and ready to be integrated. Committing code less frequently may seem like a good option initially, but it can create a massive amount of conflicts when the code is eventually pushed, making it a less desirable solution. Moreover, manual code review before every commit is time-consuming and prone to human errors. Besides, switching to a different CI tool would not necessarily solve the issue as the problem lies not with the tool but the code integration process itself.
