How do I get all the occasions of <div data-test="value"> on a page?

    <div class="section" data-test="123">
        <div class="top">

        <div class="bottom" data-test="123">

    <div class="section">
        <p data-test="123">

...returns reference to the three occasions above and allows me to perform actions on the node they sit on.

I know $(".section").data("test") will get it but I want to get it for all occasions on any page with any HTML and any classes.

I tried $('body').data('test') and $('div').data('test') but nothing.
