### Question:
App { public static void main(String[] args) throws IOException, ClassNotFoundException { var fishV1 = new RainbowFish("Zed", 10, 11, 12); LOGGER.info("fishV1 name={} age={} length={} weight={}", fishV1.getName(), fishV1.getAge(), fishV1.getLengthMeters(), fishV1.getWeightTons()); RainbowFishSerializer.writeV1(fishV1, "fish1.out"); var deserializedRainbowFishV1 = RainbowFishSerializer.readV1("fish1.out"); LOGGER.info("deserializedFishV1 name={} age={} length={} weight={}", deserializedRainbowFishV1.getName(), deserializedRainbowFishV1.getAge(), deserializedRainbowFishV1.getLengthMeters(), deserializedRainbowFishV1.getWeightTons()); var fishV2 = new RainbowFishV2("Scar", 5, 12, 15, true, true, true); LOGGER.info( "fishV2 name={} age={} length={} weight={} sleeping={} hungry={} angry={}", fishV2.getName(), fishV2.getAge(), fishV2.getLengthMeters(), fishV2.getWeightTons(), fishV2.getHungry(), fishV2.getAngry(), fishV2.getSleeping()); RainbowFishSerializer.writeV2(fishV2, "fish2.out"); var deserializedFishV2 = RainbowFishSerializer.readV1("fish2.out"); LOGGER.info("deserializedFishV2 name={} age={} length={} weight={}", deserializedFishV2.getName(), deserializedFishV2.getAge(), deserializedFishV2.getLengthMeters(), deserializedFishV2.getWeightTons()); }  static void main(String[] args);  }### Answer:
@Test void shouldExecuteWithoutException() { assertDoesNotThrow(() -> App.main(new String[]{})); }
