茉莉，JQuery UI addClass测试问题

it(\"should use jquery ui\", function() {
  runs(function() {
    expect(el.hasClass(\"fdsa\")).toBeFalsy();
    el.addClass(\"fdsa\", 1000);
    expect(el.hasClass(\"fdsa\")).toBeFalsy();// this should not be failing, but it is
  });

  waits(1000);

  runs(function() {
    expect(el.hasClass(\"fdsa\")).toBeTruthy();
  });
});

el = $($(\"div\")[0]);
el.addClass(\"qwer\", 1000);
console.log(el.hasClass(\"qwer\")); // output is \"false\"
setTimeout( function(){
  console.log(el.hasClass(\"qwer\")); // output is \"true\"
}, 1001);
