Weird migration problem while testing

Hi, I'm implementing tests in my app and I've got this weird situation.

I've done several change to my users tables with using migration obviously.

When I try a php artisan migrate:fresh everything is working.

On local env, User::factory()->create() works too but in this test I've got an error this specific error General error: 1 table users has no column named firstname (SQL: insert into "users" ("firstname", "lastname", "phone", "email", "email_verified_at", "address", "address_1", "zip_code", "city", "password", "updated_at", "created_at") values (David, Martinez, +33 7 90 93 44 45, [email protected], 2014-08-04 00:00:00, 167, rue Maurice, ?, 07599, Denisboeuf, $2y$04$amnt7y7.ydQ0XPCE2nK0GuKj6ftiHqnUVkODSuQC8Yo3djmA4iN.K, 2022-08-25 13:37:47, 2022-08-25 13:37:47))

I've added a var_dump on the up method in the migration (I can see yhe up method is called in the test)

The test:

test('admins can browses clients', function() {
    $clients = User::factory()->create();

    $this->get(route('clients.index'))
        ->assertSuccessful()
        ->assertSee($clients[0]->firstname)
        ->assertSee($clients[1]->firstname);
});

In order to debug I've added this line of code in my test

dd(\Illuminate\Support\Facades\Schema::getColumnListing("users"));

But the results show there is no "firstname" column (wtf ?)

Here is the latest migration for the users table

return new class extends Migration {
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::table('users', function (Blueprint $table) {
            $table->dropColumn(['name']);

            $table->string('firstname')->after('id');
            $table->string('lastname')->after('firstname');
            $table->string('phone', 20)->after('lastname');
            $table->string('address')->nullable()->default(null)->after('email_verified_at');
            $table->string('address_1')->nullable()->default(null)->after('address');
            $table->string('zip_code', 10)->nullable()->default(null)->after('address_1');
            $table->string('city')->nullable()->default(null)->after('zip_code');
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::table('users', function (Blueprint $table) {
            $table->string('name')->after('id');

            $table->dropColumn(['firstname', 'lastname', 'phone', 'address', 'address_1', 'zip_code', 'city']);
        });
    }
};

Is there anything I'm missing ? A typo ? A can't see what's the problem.

All other tests are working great

thanks
