here is how i connect all this stuff for test

const mockAdminGuard = {
    canActivate: jest.fn(() => true),
  };

  beforeEach(async () => {
    const module: TestingModule = await Test.createTestingModule({
      controllers: [UsersController],
      providers: [
        {
          provide: UsersService,
          useValue: mockUsersService,
        },
        {
          provide: AdminGuard,
          useValue: mockAdminGuard,
        },
      ],
    }).compile();

here is test which is not mocking guard

describe('getUsers', () => {
    it('should return error when request is not from admin', async () => {
      mockAdminGuard.canActivate.mockImplementationOnce(() => false);

      const response = await userController.getUsers();

      console.log(response);

      expect(response).toBe(12312321);
    });
  });

here is controller

@UseGuards(AdminGuard)
  @Get()
  async getUsers(): Promise<User[]> {
    return await this.usersService.findAll();
  }

here is admin guard

@Injectable()
export class AdminGuard implements CanActivate {
  constructor(private reflector: Reflector) {}

  async canActivate(
    context: ExecutionContext,
  ): Promise<boolean> {
    const request = context.switchToHttp().getRequest();
    const user = await User.findOne({where: { id: request.user.sub}});

    // Return a boolean indicating if the user has the 'admin' role
    return user && user.role === 'admin';
  }
}

everything works fine for requests, but i cant figure out how to write test for this one
