Laravel- view is not working

I am using Ubuntu 16.04 and installed Laravel 5.3 on desktop/Laravel/test directory. I have created a test.blade.php file in resources/view directory. I have also created routes.php in app/Http directory and added following code:

Route::get('/', function(){
    return view('test');
});

When I enter command in terminal: php artisan serve and go to http://localhost:8000 url in browser, it shows default page of laravel after installation. Why it is not showing view I have created? I have also tried writing following code in routes.php:

Route::get('/', function(){
    echo "Test";
})

But still it doesn't work. Is there anything I am missing?
