Should you write tests before code?
Writing the tests first: The tests should be written before the functionality that is to be tested. This has been claimed to have many benefits. It helps ensure that the application is written for testability, as the developers must consider how to test the application from the outset rather than adding it later.
When should code review be performed?
Code reviews should happen after automated checks (tests, style, other CI) have completed successfully, but before the code merges to the repository’s mainline branch. We generally don’t perform formal code review of aggregate changes since the last release.
What works well before code review?
Authors should annotate code before the review occurs because annotations guide the reviewer through the changes, showing which files to look at first and defending the reason behind each code modification. Annotations should be directed at other reviewers to ease the process and provide more depth in context.
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 difference between check in and code review?
If you practice code review before doing a check-in then code review falls between two testing stages: you as a developer test your code first, your peer does code review, you check it in, then later dedicated testers will perform more thorough individual and integrations tests. Test first. Test last.
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.
What should be included in a pre commit review?
On Phabricator Differential, code submitted for pre-commit review includes a Test Plan from the author. Of course, when testing code, make sure you’re building correctly. If the project has a build system, you should be able to use it. If the Continuous Integration system reported successfully building the code, you should be able to as well.
