SIMULATION
Initialize the default main branch, if it does not exist already.
In the User1-12345678 Azure DevOps project, you need to implement an approval process for the default main branch.
The process must use the four-eyes principle and have at least one approval on every iteration.
Configure branch policies
Phase 1. Select the correct branch
Step 1: To manage branch policies, select Repos > Branches to open the Branches page in the web portal.
You can also get to branch policy settings with Project Settings > Repository> Policies > Branch Policies > <Branch Name>.
Step 2: To set branch policies, locate the branch you want to manage. You can browse the list or search for your branch in the Search branch name box at upper right. [Select the default main branch]
Select the More options icon next to the branch, and then select Branch policies from the context menu.
Phase 2: Configure approval
Require a minimum number of reviewers
Code reviews are important for software development projects. To ensure that teams review and approve PRs, you can require approval from a minimum number of reviewers. The basic policy requires that a specified number of reviewers approve the code with no rejections.
Step 3: To set the policy, under Branch Policies, set Require a minimum number of reviewers to On. Enter the required number of reviewers, and select any of the following options.
3a. [Select: Minimum number of reviewers: 2]
3b. [Select: When new changes are pushed: ]
3c [Select Require at least one approval on the last approval of the last iternation]
