Create a file, checksum the file to be corrupted then compare it's checksum +# with the one obtained after healing under different testing scenarios: +# 1. Test healing (aka corrective) recv from a full send file +# 2. Test healing recv (aka heal recv) from an incremental send file +# 3. Test healing recv when compression on-disk is off but source was compressed +# 4. Test heal recv when compression on-disk is on but source was uncompressed +# 5. Test heal recv when compression doesn't match between send file and on-disk +# 6. Test healing recv of an encrypted dataset using an unencrypted send file +# 7. Test healing recv (on an encrypted dataset) using a raw send file +# 8. Test healing when specifying destination filesystem only (no snapshot) +# 9.
