Why are there multiple test cases? HashAvatar has no conditional code so every call has 100% coverage.

According to HashAvatar's comment, they are for different cases:

  • 1 & 8 : different id, different hash
  • 1024, buff.Bytes() & 1024, []byte{}: different content, different hash

ps: actually the test could be simplified by removing the myImage, because HashAvatar can be tested with byte slice directly.
