When using Form::open() - if you don't specify a method (GET or POST), it will default to submitting the form as a POST request. You have your welcome route set up to handle a GET request.
For a login form, I'd recommend you stick with a POST request, which will require you to update your route definition to;
Route::post('welcome','testController#getIndex');
For future reference, you can specify a method when opening your form as follows:
{!! Form::open(['url' => 'welcome', 'method' => 'GET']) !!}
