For CCoinsViewCache instances backed by either another cache instance or leveldb, test cache behavior and flag state (DIRTY/FRESH) by.

  1. Adding a random coin to the child-most cache,
  2. Flushing all caches (without erasing),
  3. Ensure the entry still exists in the cache and has been written to parent,
  4. (if do_erasing_flush) Flushing the caches again (with erasing),
  5. (if do_erasing_flush) Ensure the entry has been written to the parent and is no longer in the cache,
  6. Spend the coin, ensure it no longer exists in the parent.
