As stated, use pointers. But, then the local variable being returned must be 'static'. Also, you need some way of knowing the array's size in the calling function:

```cpp
void setup() {
  Serial.begin (115200);
}

void loop() {
  int *returnedArray;
  returnedArray = Test();
  for (uint8_t i = 0; i < 3; i++) {
    Serial.println(returnedArray[i]);
  }
}

int *Test() {
  static int test[] = {1, 2, 3};
  return test;
}

```
