When writing some db dependent tests for bugs 8800, 9074 and 9078 I noticed that we have inconsistent data in the localized SQL files. Such inconsistency might be a problem, or not depending on what premises we agree on. As I see it, it is difficult to maintain consistency as different common use cases may require different sample data. Also, for testing purposes we might need (like i do on this bugs) special holidays set for my test cases, but maybe our users rely on the sample data for filling the DB with some good defaults... So, my questions are: 1) Do we expect our unit tests go ok with ANY localised data set? 2) Do we need a special set of data for testing purposes (from the dev POV)? As for (1) remember the Holidays.t db dependent tests, that need to cover all the use cases and might not be a good default for a new library. Also Circulation db dependent tests shoud need bad end-user defaults. Regards To+
