I'm trying to write a test that checks whether or not an element has a class:
element('#header-menu .menu-component-item a').query(function(els, done) {
  var el = els.eq(4);
  el.click();
  sleep(.25);
  expect(browser().location().path()).toBe(el.attr('href'));
  expect(el.attr('class')).toContain('selected');
  done();
});
The issue is that I keep getting the error TypeError: Cannot read property 'indexOf' of undefined. I expected el.attr('class') to be a future but I'm not sure why it isn't. Is there another way around this?
