How Can This Be Tested?

Test Scenario 1: Authenticated user with following relationships

1. Log in as User A
2. Follow User B and User C (but not User D)
3. Make a GET request to the users endpoint
4. Verify the response includes is_following: true for User B and User C
5. Verify the response includes is_following: false for User D

Test Scenario 2: Paginated results

1. Log in as a user with multiple following relationships
2. Request users with pagination parameters (e.g., page=1&per_page=5)
3. Verify each user object has the is_following flag
4. Verify the flag accurately reflects the following status

Test Scenario 3: Unauthenticated request

1. Make a GET request to the users endpoint without authentication
2. Verify all users have is_following: false

Test Scenario 4: With search and filters

1. Log in as a user
2. Use search parameters (e.g., search=john)
3. Use filter types (e.g., filter_type=trending)
4. Verify is_following flag is present and accurate in all cases
