I cant access API route get via POST MAN in Laravel 6

Hello , I have this route -

Route::name('test')->get('test', 'TestController@index');

if I add it in routes/web.php , I will be able to access my index of TestController by POST MAN . BUT if I add in routes/api.php , it will gives me 404 Error .

In Laravel 5.8 It works , but in Laravel 6 , it is not working . I dont know if I am doing something wrong . Did something changed in routes API between Laravel 5.8 to 6 ?

Thanks
