More Details

  • I've implemented the review around files and not changesets, because at the end, I want to be able to tell for the specific project if all the files went through code review process or not - the project status.
  • Suppose you have some project that you are in charge and many developers do write code for it. And there is a group of reviewrs that review the developers code. Is is very difficult to keep track of changes developers do, but simple to find out what files have already been reviewd (by reviewers) and what were not.
  • Using this extension, Developer can mark his files (when finished development process) as "Ready for review" and send notice to reviewer. Reviewer will pick up the changeset (because changesets are stored in the code review database) and perform code review (put notes inside the developer's code). Afterwards Reviewr will mark the files as "Review Completed". and return the notice to the developer.
  • The project manager can follow every time what is going on with his/her project.
