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

Answer

Solution:

It was not possible.

However, I have made a plugin to Kahlan that allows to "extract" functions from any file and skip all other code. It will not allow to exactly "mock" statements, but it will allow to test isolated functions. I made pull-request and if it will not be accepted, I will make a separate packagist composer packet and update this answer.

Changes can be found here:

Example of usage:

File:

<?php
require_once 'something';  // This string will be "skipped" on test

do_something();  // This string too

function test()
{
    return 42;
}
Copy code

Test for this file with plugin:

<?php

use Kahlan\Plugin\Isolator;

Isolator::isolate(dirname(__DIR__).'/../test.php');

describe('test()', function() {
    it('returns 42', function() {
        expect(test())->toBe(42);
    });
});
Copy code
