How to check if an element does NOT have a specifi

Question

How do I check if there isn't a class. For example, I know how to check to see if it has the class "test", but how do I check to see if it doesn't have the class "test"?

if($(this).hasClass("test")){
}

sdleihssirhc's answer is of course the correct one for the case in the question, but just as a reference if you need to select elements that don't have a certain class, you can use the not selector:

// select all divs that don't have class test
$( 'div' ).not( ".test" );
$( 'div:not(.test)' );  // <-- alternative
