"Including the test suite which is something lacking in SQLite"

That's not entirely true. SQLite has a TON of tests that are part of the public domain project: https://github.com/sqlite/sqlite/tree/master/test

They do have a test suite that's private which I understand to be more about testing for different hardware - they sell access to that for companies that want SQLite to work on their custom embedded hardware, details here: https://sqlite.org/th3.html

> SQLite Test Harness #3 (hereafter "TH3") is one of three test harnesses used for testing SQLite.
