Add Unit Tests to Ensure Robustness of Looking for Non-Existent Keys #97
Description
Description
- While working on Add Native Configuration to PlatformIO #94, an issue was encountered where EmbedDB had a segmentation fault because it tried to search for a key that was less than the recorded min key in the database.
- We should investigate the robustness of the code by writing some more unit tests to ensure that the database does not crash when some key edge cases are encountered, such as:
- Querying for a key less than the min key
- Querying for a key greater than the max key
- Looking for a key between keys in the database that does not exist
- Querying records at a later point in the database when some earlier pages have been flushed
