Shortcodes not working

Hey guys,

I am trying to get a feel for shortcodes, but my test is not working properly. I want to to change [test] with <p>TEST TEXT</p>, but when I put [test] in the page editor, no text shows up.

Here is what is in my functions.php:

function test() {
  return '<p>TEST TEXT</p>';
}

add_shortcode('test', 'test');

and then I have [test] as the only thing on the page. I am running on localhost, if that matters. Does anyone know what I am doing wrong?

Thank you!
