delete only works for properties of objects. If test() was inside an object, you could delete it, but if it's a stand alone function, you're stuck with it, unless you nullify it or define it as something else.

Object Delete

var obj = {
    test: function() {
        console.log("I'm a test");
    }
}

obj.test(); //I'm a test
delete obj.test;
obj.test(); //Nothin'

Function Reassign

function test() {
    console.log("I'm a test");
}

test(); // I'm a test

delete test;

test = undefined;

test(); // TypeError
