因此，在实现新功能之前，我正在进行一些单元测试。我运行测试，但失败并出现 OverflowException ：最大重试次数达到 10000 次，但未找到唯一值 这是我正在运行的测试。

public function test_job_factory()
    {
        $client = Client::factory()->create();
        $accountHandler = AccountHandler::factory()->create();
        $user = User::factory()->create();

        $this->post('/login', [
            'email' => $user->email,
            'password' => 'password',
        ]);

        $user->givePermissionTo( 'manage jobs' );
        $clientContact = ClientContact::factory()->create();
        $job = Job::factory()->create();

        $this->assertTrue($job->id > 0);
    }

该错误似乎是在创建作业本身时发生的。上面的测试测试了其他工厂并且正在工作。

这是 JobFactory.php 文件：

<?php

namespace Database\Factories;

use App\Models\AccountHandler;
use App\Models\Client;
use App\Models\ClientContact;
use App\Models\Job;
use App\Models\User;
use Illuminate\Database\Eloquent\Factories\Factory;

/**
 * @extends \Illuminate\Database\Eloquent\Factories\Factory<\App\Models\Job>
 */
class JobFactory extends Factory
{
    protected $model = Job::class;

    /**
     * Define the model's default state.
     *
     * @return array<string, mixed>
     */
    public function definition()
    {
        return [
            'title'              => $this->faker->company(),
            'is_active'          => 1,
            'is_draft'           => 0,
            'client_id'          => $this->faker->unique()->numberBetween(1, Client::count()),
            'account_handler_id' => $this->faker->unique()->numberBetween(1, AccountHandler::count()),
            'eclipse_contact_id' => $this->faker->unique()->numberBetween(1, User::count()),
            'client_contact_id'  => $this->faker->unique()->numberBetween(1, ClientContact::count()),
            'description'        => $this->faker->paragraphs(1),
        ];
    }
}

以及为此的迁移（create_jobs_table.php）：

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

return new class extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('jobs', function (Blueprint $table) {
            $table->id('number');
            $table->boolean( 'is_active' )->default(true);
            $table->boolean( 'is_complete' )->default(true);
            $table->string('title', 64)->nullable();
            $table->timestamps();
            $table->foreignId('author')->nullable()->constrained()->references('id')->on('users');
            $table->text('description')->nullable();
            $table->foreignId('client_id')->nullable()->constrained()->references('id')->on('clients');
            $table->foreignId('client_contact_id')->nullable()->constrained()->references('id')->on('client_contacts');
            $table->foreignId('account_handler_id')->nullable()->constrained()->references('id')->on('account_handlers');
            $table->date('expiry_date')->nullable();
            $table->date('artwork_deadline')->nullable();
            $table->date('proof_deadline')->nullable();
            $table->integer('redirect')->nullable();
            $table->boolean( 'is_draft' )->default(true);
            $table->foreignId('eclipse_contact_id')->nullable()->constrained()->references('id')->on('users');
            $table->foreignId('subscription_id')->nullable()->constrained()->references('id')->on('subscriptions');
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('jobs');
    }
};

那么出了什么问题，为什么会出现这个循环？我已经添加了创建作业所需的最少数据，因此不知道我错过了什么。

谢谢

*** 编辑 *** 我被要求提供一个链接，指向我发现使用 unique 和 numberBetween 的不好做法的地方，这里是一个示例 Laravel 工厂错误“最大重试次数达到 10000 次，但没有找到唯一值”，当我使用 unique Faker 方法时，这不会像你那样工作期待！
