AssertSee with Locale middleware in Dusk

[barbosa89]

Hi guys, first of all, I am very thankful to you, because PHP is great since you created the Laravel framework.

I tell you that I am trying to do a simple test with Dusk and it is failing. The procedure is as follows:

1. Create a middleware to detect the preferred language.
2. I have the translation files in English and Spanish.
3. I made the assertion to check that it is rendered in view.

When I run the Dusk command the test fails, so I created a script command in Composer to call the Dusk command and the test was successful. Summary:

Without Locale middleware:

php artisan dusk -> successful
composer dusk -> successful

With Locale middleware:

php artisan dusk -> Fail
composer dusk -> successful

Apparently, running the Dusk command from artisan, the browser has the language in Spanish, and Dusk from Composer, the browser has the language in English.

I do not know if it is simply a configuration error or if I am doing a wrong procedure.

The middleware:

    public function handle(Request $request, Closure $next)
    {
        $language = $request->getPreferredLanguage(['en', 'es']) ?? 'en';

        app()->setLocale($language);

        return $next($request);
    }

The Dusk test:

    public function testBasicExample()
    {
        $this->browse(function (Browser $browser) {
            $browser->visit('/')
                    ->assertSee(trans('common.hello'));
        });
    }

The composer command:

"dusk": "@php artisan dusk"

I made a repository with the example code and put Logs to check the states of the Locale: https://github.com/barbosa89/dusky.
