Laravel testing. Reset controller DI while test

Question

I have a Laravel controller with DI in

__construct(Model1 $m1, Model2 $m2, $SomeService $s) {
 $this->m1 = $m1;
 $this->m2 = $m2;
 $this->s = $s;
}

I have an API test with call or endpoint based on this controller. I'm doing 8 same API url calls with different payload. It seems z controller constructor process 1 time and after that works with constructed dependencies.

$response1 = $this->actingAs($admin,'api')->json('POST', '/api/someURL', $payload1);

$response2 = $this->actingAs($admin,'api')->json('POST', '/api/someURL', $payload2);

$responseN = $this->actingAs($admin,'api')->json('POST', '/api/someURL', $payloadN);

Can I somehow set dependencies before each API call in test?

You can unset the controller instance between request from the route using:

$response1 = $this->actingAs($admin,'api')->json('POST', '/api/someURL', $payload1);

// unset the controller
$this->app->get(Illuminate\Routing\Route::class)->controller = null;

$response2 = $this->actingAs($admin,'api')->json('POST', '/api/someURL', $payload2);

// unset the controller
$this->app->get(Illuminate\Routing\Route::class)->controller = null;

$responseN = $this->actingAs($admin,'api')->json('POST', '/api/someURL', $payloadN);

Why?

In Illuminate\Routing\Router Laravel binds the current route to the container:

protected function findRoute($request)
{
    $this->current = $route = $this->routes->match($request);
    $this->container->instance(Route::class, $route);
    return $route;
}

and when the route controller is run in Illuminate\Routing\Route, the controller instance is stored in Route object:

public function getController()
{
    if (! $this->controller) {
        $class = $this->parseControllerCallback()[0];
        $this->controller = $this->container->make(ltrim($class, '\\'));
    }
    return $this->controller;
}
