    I just ran into this exact same problem while trying to use Zepto matchers for Jasmine. It seems like Zepto wraps objects using an internal Z function that is only accessible by the closure. I tried exposing it by mapping it to $.Z, which works

    $(el) instanceof $.Z // => true
    

    but it still doesn’t work with the matchers for some reason. I have created an issue on Zepto’s github, so hopefully it’s something that can be added in.
