Symfony ObjectProphecy 以不同的方式对待数组和对象 - 无法更改在 setUp 方法中初始化的数组

问：

与此相关

我正在尝试这个测试代码

<?php

use Monolog\Test\TestCase;
use Prophecy\Prophecy\ObjectProphecy;
use Prophecy\Prophet;

class MyBar {
    public int $bar = 0;
}

class MyFoo {
    public function fooArray(): array {
        return [];
    }

    public function fooBar(): MyBar {
        return new MyBar();
    }

    public function fooInt(): int {
        return 0;
    }
}

final class SimpleTest extends TestCase
{
    private Prophet $prophet;
    private ObjectProphecy $mock;
    private array $myArray;
    private MyBar $myBar;
    private int $myInt;

    public function getProphet(): Prophet {
        return $this->prophet;
    }

    protected function setUp(): void {
        $this->prophet = new Prophet();
        $this->myArray = [0];
        $this->myBar = new MyBar();
        $this->myInt = 0;
        $this->mock = $this->getProphet()->prophesize(MyFoo::class);
        $this->mock->fooArray()->willReturn($this->myArray);
        $this->mock->fooBar()->willReturn($this->myBar);
        $this->mock->fooInt()->willReturn($this->myInt);
    }
    
    public function test(): void {
        $this->myArray = [1];
        $this->assertEquals([0], $this->mock->reveal()->fooArray());

        $this->myBar->bar = 1;
        $this->assertEquals(1, $this->mock->reveal()->fooBar()->bar);

        $this->myInt = 1;
        $this->assertEquals(0, $this->mock->reveal()->fooInt());
    }
}

请注意测试函数的区别，数组不会更新，int 也不会更新，但对象会更新。$myArray$myInt$myBar

• 为什么他们不以同样的方式行事？
• 让数组像对象一样工作的推荐方法是什么？

我正在考虑将数组作为引用传递，但据此，使用 .我在顶部链接的问题的答案建议使用另一种方法的解决方案，但我试图看看 中是否有解决方案。ObjectProphecyMockObjectObjectProphecy
