chai as promise call function once

Question

How can I do this with chai-as-promised:

Currently I am using chai expect:

return User.auth(data).then(function(usr){
  expect(usr).to.have.property('user', 'alvin');
  expect(usr).to.have.property('email', '[email protected]');
});

for chai-as-promisied, I can call mulutiple call but I would like to call once:

return User.auth(data).should.eventually.have.property('');
return User.auth(data).should.eventually.have.property('');

---

The solution:

it('should return user', function(){
            this.timeout(15000);            
            let data = { req: {
                email: '[email protected]'
            }};

            let expected = {
                email: '[email protected]'
            };

            return 
 User.auth(data).should.be.fulfilled.and.eventually.include(expected);
        });
