The new Engima release 0.4 is about databases. It creates a new SQLite database and populates it. This is currently only supported from unit tests, but several preparations have been made to access the data in the application itself. You can download it from https://gitlab.com/jkampherbeek/enigma.git .
Additionally, several tests are now based on Fakes. The number of tests is now about 200.
An updated version of the technical documentation is also available.
