批量更新和检查属性更改不起作用（Laravel）

Question

我有这段代码，我想在用户表上执行批量更新和检查属性更改。但是，当我运行 php artisan 测试时，测试文件中有一个错误说“此测试没有执行任何断言”。我检查了用户表，但没有任何变化。有人能帮我吗？谢谢

<?php

namespace Tests\Feature;

use App\Models\Post;
//use http\Client\Curl\User;
use Illuminate\Foundation\Testing\RefreshDatabase;
use Illuminate\Foundation\Testing\WithFaker;
use Tests\TestCase;
use App\Models\User;

class PostExampleTest extends TestCase
{
    /**
     * A basic feature test example.
     *
     * @return void
     */
    public function test_example()
    {
        $post = Post::factory()->create();
        //Create 20 more posts
        $post1 = Post::factory()->count(20)->create();

        $post->title = 'Post Test';
        $post->save();

        //Create 10 more users
        $makeTenUsers = User::factory()->count(10)->create();
    $user = User::find(1);
    $user->name = 'Kaeith';
    $user->save();

    //Mass Updates
    User::where('email_verified_at', '2021-02-28 23:50:21')
        ->update(['email'=>'kaeith']);

    //Examining Attribute Changes
    $post->isDirty();
    $post->isDirty('title');

    $user->isClean();
    $user->isClean('name');
}
}

user表的结构是'id', 'name', 'email', 'email_verified_at', 'password', 'created_at'

好吧，你没有做出任何断言。 isDirty()/isClean() 只返回布尔值。这些都不是：

$post->isDirty();
$post->isDirty('title');

$user->isClean();
$user->isClean('name');

是断言。这是一个断言。

// $this being the class that extends Tests\TestCase
$this->assertEquals($post->isDirty(), false);

在您的代码中：

• $post->isDirty(); 应该等于 false，因为 $post 的更改已保存 ($post->save();)
• $post->isDirty('title'); 与此相同。

大规模更新不会更改并保存每个模型。他们完全绕过了 eloquent 的事件。考虑到这一点：

• $user->isClean(); 应该等于 true，因为 $user 的更改已经保存 ($user->save();)
• $user->isClean('name'); 与此相同。

User::factory()->create();

$user = User::first();
$user->isClean();        // true
$user->isClean('name');  // true
$user->isClean('email'); // true
$user->isDirty();        // false
$user->isDirty'name');   // false
$user->isDirty('email'); // false

$user->name .= 'a';
$user->isClean();        // false
$user->isClean('name');  // false
$user->isClean('email'); // true
$user->isDirty();        // true
$user->isDirty'name');   // true
$user->isDirty('email'); // false

$user->save();
$user->isClean();        // true
$user->isClean('name');  // true
$user->isClean('email'); // true
$user->isDirty();        // false
$user->isDirty'name');   // false
$user->isDirty('email'); // false

使用简单的assertEquals 断言

User::factory()->create();

$user = User::first();
$this->assertEquals($user->isClean(), true);
$this->assertEquals($user->isClean('name'), true);
$this->assertEquals($user->isClean('email'), true);
$this->assertEquals($user->isDirty(), false);
$this->assertEquals($user->isDirty'name'), false);
$this->assertEquals($user->isDirty('email'), false);

$user->name = 'a';
$this->assertEquals($user->isClean(), false);
$this->assertEquals($user->isClean('name'), false);
$this->assertEquals($user->isClean('email'), true);
$this->assertEquals($user->isDirty(), true);
$this->assertEquals($user->isDirty'name'), true);
$this->assertEquals($user->isDirty('email'), false);

$user->save();
$this->assertEquals($user->isClean(), true);
$this->assertEquals($user->isClean('name'), true);
$this->assertEquals($user->isClean('email'), true);
$this->assertEquals($user->isDirty(), false);
$this->assertEquals($user->isDirty'name'), false);
$this->assertEquals($user->isDirty('email'), false);
