如何测试用户是否有查看权限

import unittest

class PermissionTest(unittest.TestCase):
    def test_has_permission(self):
        user = User(role='admin')
        self.assertTrue(user.has_permission('view_dashboard'))

if __name__ == '__main__':
    unittest.main()

from selenium import webdriver

def test_view_permission():
    driver = webdriver.Chrome()
    driver.get('http://example.com/dashboard')
    
    user = User(role='guest')
    if not user.has_permission('view_dashboard'):
        assert 'Access Denied' in driver.page_source
    
    driver.quit()

describe('Dashboard Access', () => {
    it('should deny access to guests', () => {
        cy.visit('/dashboard');
        cy.login('guest@example.com', 'password');
        cy.contains('Access Denied').should('be.visible');
    });
});
