But webappkit is still an active projet. Release 0.13 is on tracks, and will provide some new features such as an install page (for admin interface) and kit creation from the admin.
Unit testing has also been changed, to be easier. No more unit tests tool to configure, jut put your tests case in a tests/ folder. Database tests are still supported by creating tests/setup.sql and tests/teardown.sql files.
Library kits are maturing, too. Have a look at webappkit.db (database) and webappkit.fs (filesystem).
