Laravel 5, how to run a specific method according to the URL received

In my routes files I have a bunch or routes for testing purposes:

/** testing controllers */
Route::get('viewemail', 'TestController@viewemail');
Route::get('restore', 'TestController@restore');
Route::get('sendemail', 'TestController@send_email');
Route::get('socket', 'TestController@socket');
Route::get('colors', 'TestController@colors');
Route::get('view', 'TestController@view_test');
Route::get('numbers', 'TestController@numbers');
Route::get('ncf', 'TestController@ncf');
Route::get('dates', 'TestController@dates');
Route::get('print', 'TestController@printer');
Route::get('{variable}', 'TestController@execute');
/** End of testing controllers */ 

I want to eliminate all those routes and simple use the name of the given URL to call and return the method:

I have accomplished that in this way:

Route::get('{variable}', 'TestController@execute');

And in my testing controller:

public function execute($method){
    return $this->$method();
}

Basically what I want to know if Laravel has a built in solution to do this, I was reading the documentation but couldn't find any way to accomplish this.
