Unable to locate factory for [Laravel\Passport\Client] - php

Question

I have a laravel app with passport installed to manage api auth. I'm trying to write some tests but I'm unable to create a Client as per the docs on laravel. I've googled similar SO answers but they all suggest using setUp and tearDown methods which I am doing. When I run the test I get
InvalidArgumentException
Unable to locate factory for [Laravel\Passport\Client].
How can I get this to work?
Below is my code. I have included the Client model from the passport package and I am using the setUp and tearDown methods as suggested in similar SO answers.
I've tried composer dump-autoload and php artisan config:cache.
use Laravel\Passport\Passport;
use Laravel\Passport\Client;
...
use RefreshDatabase;
protected function setUp(): void
{
parent::setUp();
}
protected function tearDown(): void
{
parent::tearDown();
}
public function testAPIEndpointFailsWhenNoParamIsSet()
{
Passport::actingAsClient(
factory(Client::class)->create(),
['*']
);
$response = $this->postJson('/api/endpoint', [
'param' => ''
]);
$response->assertStatus(401)
->assertJson(['message' => 'Unauthenticated.']);
}

passport client factory should be existed on publishing ...
if it did not .... make it your self:
from : here
use Laravel\Passport\Passport;
use Laravel\Passport\Client;
$factory->define(Client::class, function (Faker $faker) {
return [
'user_id' => null,
'name' => $faker->company,
'secret' => Str::random(40),
'redirect' => $faker->url,
'personal_access_client' => 0,
'password_client' => 0,
'revoked' => 0,
];
});
