I don't know how much the test suite costs by itself, but it is included in Sqlite Consortium membership, which is a typical open source support-style business model. For $75k, you get almost a month of sqlite developer time and tons of support (eg their home phone numbers). Not a bad deal for companies that want deep sqlite integration or customized versions that fit on tight embedded systems. https://www.sqlite.org/consortium.html https://www.sqlite.org/consortium.html
