I have test data in JSON , how can I iterate over this test data for the test to run for each set? testData.json

[
       {
        "Username ": "abc",
        "Password": “xyz",
        "role": "customer" 
       
    },
     {
       "Username ": "def",
        "Password”: "abc123”,
         "role": "manager"
     } 
]

feature file: test.feature

Feature: verifying marks
Scenario Outline: Validate marks for each student
Given user open student page------first page
when user login with <username > and <password >----second page
Then verify <username> and <role> ----third page

How can I iterate using json data for username and password.I am using cucumber page objects model.

Appreciate any insights. Thanks
