What should a code review say?

What tools and techniques do you use to improve code quality?
How to Improve Code Quality: A Closer Look
- Use a Coding Standard. Using a coding standard is one of the best ways to ensure high quality code.
- Analyze Code — Before Code Reviews. Quality should be a priority from the very start of development.
- Follow Code Review Best Practices.
- Refactor Legacy Code (When Necessary)
When do code reviewers not have to test the code?
By the time the code gets to a code review, the developer should have written unit tests, successfully built both the code under review and the unit tests, and have all currently-written unit tests passing. Because of this, the code reviewer should not have to test the code – the author of the code should have already done it.
What’s the purpose of commenting in a code review?
The purpose here is to test the code outside of the automatic unit tests; in short, you’re testing what the CI cannot test. If this doesn’t apply, and there is truly nothing to manually test, don’t waste your time. Commenting matters.
Where can I do a good code review?
Nearly any healthy programming workflow will involve code review at some point in the process. This may be a Pull Request on GitHub, a Differential Revision on Phabricator, a Crucible Review on Atlassian, or any number of other review tools. But however you do it, not all code reviews are created equal.
Why are code reviews so important in DevOps?
Code reviews are important for DevOps because they help teams achieve quality and speed to add more value to a product. There isn’t a one size fits all approach to code review. There are different models for code reviews in DevOps depending on when it is done in the lifecycle of changes in the product.
