Using the new PackageLoader feature when creating unit tests for DBD-PostgreSQL

Tagged:  •    •  

In the previous post I briefly mentioned the new feature of the PackageLoader that went into the development version of GNU Smalltalk. Today I am going show a usage of it.

GNU Smalltalk has a database abstraction called DBI and multiple backends (MySQL, SQLite and PostgreSQL). In general I am using the SQLite backend to develop my application and depending on the users (e.g. do I need concurrent access) I will move to PostgreSQL. When moving my new application to PostgreSQL the import of data failed and this was due some issues with the conversion of Smalltalk types to PostgreSQL.
