I am working on unit testing using sanctum. I was testing as acting as a admin using sanctum

I have make a unit test case as :

public function test_user_registration(){
         $this->withoutExceptionHandling();
         $this->withoutMiddleware();
         Bus::fake();
         $user = User::find(1);
         Sanctum::actingAs($user,['*']);
         $response = $this->post('/api/users',[
             "firstName"=>"Kamal",
             "lastName"=>"Garu",
             "email"=>"Kamasll@gmail.com",
             "roleId"=>[4],
             "defaultRoleId"=>4,
             "investorId"=>[15],
             "defaultInvestorId"=>15,
             "streetAddress"=>"Jalur Banj",
             "postalCode"=>"977",
             "city"=>"bhaktapur",
             "countryId"=>160,
             "phone"=>9741801138,
             "status"=>1,
             "emailPortfolioReport"=>0,
             "emailInvestorActivities"=>0,
             "emailMarketUpdate"=>1,
             "isdCodeId"=>149,
             "roleType"=>["investorInternational"]
         ]);
         VerifyUser::dispatch($response);
         Bus::assertDispatched(VerifyUser::class);
         $response->assertStatus(200);
     }
