Finally, thanks to the help of Domizia D’Erasmo, a new set of fully automated unit tests have been written for bdus4. These tests cover the entire lifecycle of the application, from the creation from scratch of a new application, to the configuration and data entry. The tests are available out of the box for SQLite, MySQL and PostgreSQL.
With these tests and the fixing of many bugs that have been fixed in the meantime, the first release candidate is available on GitHub.
So, stay tuned and help testing and bug detection! Read the docs and file an issue if something is not working as expected!
