within browser file object represent local file , contains file's information. when stub file object, has information not actual reference local file.

i suggest stubbing readasdataurl , check if receives file object in tests. , returning pre-defined dataurl tests.

edit

i in tests,

spyon(window, 'filereader').andreturn({     readasdataurl(){}     onloadend(){} });

you can replace readasdataurl() , onloadend() jasmine stubs , assert if called proper arguments.

edit

const filereaderspy = jasmine.createspyobj('filereader', ['readasdataurl', 'onloadend']);  spyon(window, 'filereader').andreturn(filereaderspy);  expect(filereaderspy.readasdataurl). tohavebeencalledwith(/* file object */); expect(filereaderspy.onloadend). tohavebeencalledwith(/* callback function */);

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
