Tests

[dhardy]

This is a long list of possible tests. Possibly it should be reorganised into multiple tickets; for now implemented tests will simply be removed from the list.

Reading from a fixed repo

• [ ] lists of elements
• [ ] contents of some elements
• [ ] reading from historical (not latest) states
• [ ] partitions
• [ ] Discovery of partition files

  Modifying repos (on disk)

• [ ] Repartitioning
• [ ] Merges
• [ ] "Discovery" system for updating logs, creating new logs and creating snapshots

  Special cases

Commit loops (reverting to prior states) in two cases: no snapshot within the loop (rendering the last commit of the loop useless) and with a snapshot in the loop (so that from the perspective of no history before the snapshot it is not a loop):

• [ ] creation via reverting
• [ ] creation via "accidental" modification
• [ ] reconstructing from log where no snapshots are involved
• [ ] reconstructing from log where the last state of the loop is a snapshot
• [ ] reconstructing from log where there is a snapshot in the middle of the loop
• [ ] reading elements (for the above cases)
• [ ] appending commits where the second state is a snapshot
• [ ] appending commits where the second state is not a snapshot
• [ ] mutate_meta function and usage in Partition::add_pair

  Reading damaged repos

• [ ] Snapshots with missing commits
• [ ] Commits with missing snapshots/parent states: state of incomplete information, yet some information can be recovered (e.g. elements added in the commits).

  Performance testing

• [ ] Large partitions (lots of data).
• [ ] Long partitions (lots of commits).
• [ ] Large repositories with multiple partitions.
• [ ] Dealing with corruption of one or multiple files as best as possible

Repartitioning / reclassification

• [ ] Basic case: add data until the partition needs splitting, test the split, add some more
• [ ] Resume: kill the program during a split, resume, check for no data loss
• [ ] Partial information: do a split, close, load only one half (with classifier information only from one partition), save some data, then load other half
