PHPUnit 测试 - 无法断言实际大小 11935 与预期大小 3 匹配

Question

我是 phpunit 的新手，正在尝试编写一个断言创建了三个注释的测试，但我从数据库中获取了所有注释。

    /** @test */
    public function it_gets_notes()
    {
        $address = Address::first();
        $notes = factory(AddressNote::class, 3)->create(['address_id' 
        => $address->id]);
        $found = $this->notesClass->getData(['address_id' => $address-
        >id]);
        $this->assertCount(3, $found);
    }
}

Address 和 AddressNote 模型工作正常。我想我最困惑的是 getData 方法，我知道我需要它来覆盖我的代码。有人看到我遗漏的内容会在标题中产生错误吗？

如果您需要在运行您的create 方法后检查差异，那么在添加它们之前和之后保存$found，以及减法将是您的电话号码:

public function it_gets_notes()
{
    $address = Address::first();
    $found = $this->notesClass->getData(['address_id' => $address->id]);
    $notes = factory(AddressNote::class, 3)->create(['address_id' => $address->id]);
    $foundAfter = $this->notesClass->getData(['address_id' => $address->id]);
    $difference = count($foundAfter) - count($found);
    $this->assertEquals(3, $difference);
}

请注意，您现在需要对 3 和差值使用 assertEquals() 而不是 assertCount()，因为您要比较数字。
