How can I do a branch review with gerrit? I want to analyse all branch changes in one gerrit change.
The idea is to review the code of a branch with multiple changes (commits).
If you want to review a branch with multiple commits Gerrit isn't an appropriate tool for that. Reviews in Gerrit are performed in every commit individually. Github or Bitbucket are tools suitable for branch review.
Answered your question, a suggestion: IMHO you should try to work with Gerrit, reviewing every commit individually, because it's a very nice workflow. I really like (and prefer) Gerrit strategy.
