Error : no such table exist in test laravel 8

Hi .. i just want to factory a model in my test .. and I got an error like this

SQLSTATE[HY000]: General error: 1 no such table: threads  ...

but it does exist and I have modified phpunit.xml

and I have done migration and factoring (i can factory my model in tinker )

idk where is my problem

This is my test

<?php

namespace Tests\Feature;

use App\Models\Thread;
use Illuminate\Foundation\Testing\DatabaseMigrations;
use Tests\TestCase;

class ThreadsTest extends TestCase
{
    use DatabaseMigrations;

    /** @test */
    public function a_user_can_browse_threads()
    {
        $this->withoutExceptionHandling();
        $thread = Thread::factory()->create();
        $response = $this->get('/threads');
        $response->assertSee($thread->title);
    }
}

this is my migrtion

<?php

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

class CreateThreadsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('thread', function (Blueprint $table) {
            $table->id();
            $table->foreignId('user_id');
            $table->string('title');
            $table->text('body');
            $table->timestamps();
        });
    }

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

This is factory

<?php

namespace Database\Factories;

use App\Models\Thread;
use App\Models\User;
use Illuminate\Database\Eloquent\Factories\Factory;

class ThreadFactory extends Factory
{
    /**
     * The name of the factory's corresponding model.
     *
     * @var string
     */
    protected $model = Thread::class;

    /**
     * Define the model's default state.
     *
     * @return array
     */
    public function definition()
    {
        return [
            'user_id' => User::factory(),
            'title' => $this->faker->title,
            'body' => $this->faker->paragraph,
        ];
    }
}

this is phpunit.xml
