Javascript单元测试Jasmine /单元测试-如何测试是否已调用私有函数？

Question

I'm trying to see if the private function has been called. Eventually I'm going to what to look for variables being set within it.

My javascript looks like the following following with a function and private function

mysamplefunction = function(item){

   /* figure out bla */       
   _myprivatefunction(item,bla)

}

_myprivatefunction = function(item, bla){


    /* do lots of exciting private things with item and bla */
}

Jasmine seems to expect the following syntax ..

 spyOn(mysamplefunction ,'_myprivatefunction');

However as we arent strictly dealing with an instance of mysamplefunction and _myprivatefunction isn't a method (its just another class) I'm not sure how to get this to work? Any ideas ??

Answer 1

If the functions are declared as you describe it, I'd expect:

spyOn(window, '_myprivatefunction');

to work.

If the function is within a closure then window will have to become something like

TopLvlHeir.2ndlvel.samplefunctionpkg.publicTesting

The only requirement is that it is an object containing a property of _myprivatefunction , eg firstArg[secondArg] is a function.
