I am new to working in branching and git.
I developed some test cases and created new branch to push the changes in that branch and opened a merge request in GitLab to be merged in master branch.
After PR, my reviewer highlighted some code refactoring and other minor changes.
Now, I have made those changes and the merge request is still open. How can I push the new changes/commit to an already opened merge request?
So, I should follow these steps? -> git add . -> git commit --amend --no-edit -> git push
No need for git commit --amend: you can make a new commit, explaining why those changes are introduced, and push.
That will update the current MR (Merge Request in GitLab parlor).
As mentioned in "Merge requests versions"/
Every time you push to a branch that is tied to a merge request, a new version of merge request diff is created.
When you visit a merge request that contains more than one pushes, you can select and compare the versions of those merge request diffs.
