Question

Answer 1

If you just want the merge can be completed successfully with some review, you can set branch policy for this master.

At this time, the process of merge into master will have some precondition, including 2 approval needed, build validation or work item state limited and etc. Without these validation, the pull request will not be completed successfully. Meanwhile, the merge will not be applied. As normal, this is a more standardized process.

Note: While you choose this method, please deny the permission of the follow pic mentioned. Or other users will bypass the validation you configured to push change into master:

In addition, if what you want is that don't want anyone to change master branch, even with validation. You can configure the security of master branch. Please set Contribute as Deny .

At this time, even all of validation is satisfied, the change still could not be merged into master.
