What does this MR do?

Display Indicator in the Approval Rules

Testing Case

Setup

Let's setup our rules in the project settings

1. Go to Settings > General > expand "Merge request approvals"
2. Add a new approval rule
3. Create a new rule named "Project Rule" and target it to any branch
4. Create a new rule named "Project Rule 2" and target it to any branch

Edit Rule

(You might need to create a new MR if you don't have any)

1. Find a MR and click "edit"
2. Edit your MR so it looks like this and click "Save changes"

3. Once you click save changes it will navigate to your MR
4. Click "edit"

• Your approval rules should look like this:
• There is an "Overridden" indicator on the project setting rule you edited
• There is an "Added for this merge request" indicator on the new local rule you created
