Trying to test with jasmine the constructor of a javascript library -


i had javascript code , wanted make reusable , testable i'm trying make library out of it. i've made in form of library i'm not able test constructor using jasmine.

my library code looks way:

window.menu = (function(){    function menu(){     this.additem('sample');   }    menu.prototype.additem(string){     console.log(string);   }    var menu = function(){     return new menu();   }  return menu; }());

now using jasmine, wan't write test testing not content of additem function, constructor, want know additem function called.

there similar question here, reason not working me. if write test:

describe("menu", function() {   it("test constructor", function() {     spyon(menu.prototype,'additem');     var newmenu = new menu();   } });

and get:

referenceerror: can't find variable: menu in file:///home/whatever/library-test/spec/menuspec.js

i don't know why happening, test code wrong or i've chosen bad approach creating testable library code?

c++ - Why doesn't unordered_set provide an array access operator -

i'm curious why stl container unordered_set , has constant time complexity random access on average, not provide method accessing elements distance first element in container. example: t& unordered_set::operator[](size_t index) { return *(begin() + index); } accessing element "by distance" implies there meaningful way measure distance. trouble std::unordered_set is is, well, unordered . hence, there no meaningful way of explaining "some distance beginning" in non-arbitrary way. if want access distance, copy data vector: std::vector tmp(unordered.begin(), unordered.end());
