Have you extend Facades class in your Test Class.
If you want to fetch all function of your files statically,
class Test extends Facades {
public static function getFacadeAccessor(){
return 'classNameWhereFunctionIsWritten' //say TestService has test() function
}
}
And Pass this classNameWhereFunctionIsWritten in your provider 'classNameWhereFunctionIsWritten' here.
