php - Is it possible to mock "require" or "require_once" statement with Kahlan? -


i have old legacy code. before starting refactoring want make unit tests code. bad thing files relies on each other "require_once" statements (hovewer, functions want test isolated).

so can't write normal tests if not able mock "require_once" statement.

i'm using kahlan framework testing. possible mock such statements? if yes, how?

it not possible.

however, have made plugin kahlan allows "extract" functions file , skip other code. not allow "mock" statements, allow test isolated functions. made pull-request , if not accepted, make separate packagist composer packet , update answer.

changes can found here:

https://github.com/lamp-of-god/kahlan/tree/isolator-plugin

example of usage:

file:

<?php require_once 'something';  // string "skipped" on test  do_something();  // string  function test() {     return 42; }

test file plugin:

<?php  use kahlan\plugin\isolator;  isolator::isolate(dirname(__dir__).'/../test.php');  describe('test()', function() {     it('returns 42', function() {         expect(test())->tobe(42);     }); });

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 <...
