Laravel how to test route prefixed with variable?

Question

Laravel

My route.php looks like

Route::group( array('prefix'=> '{lang}'), function(){

    Route::get('/',function (){

        return view('frontend.index');
    });
});

When running the test

public function testBasicExample()
    {
        $this->visit('/en/')->see('Polski');
    }

I get an error

A request to [minishop.dev/en] failed. Received status code [404].

The URL is correct, everything is OK in the browser, but the test fails...
What could be wrong?

Answer 1

Stupid, decided to write
instead
protected $baseUrl = 'minishop.dev';
