The files in this directory are used for importers' acceptance tests. These are database files created by different media players, describing music files found in ./testcollection directory. Because the database files all describe the same set of tracks, associated importers can be tested by the same set of generic tests (contained in ../TestImporterBase.cpp).
Music files contained in ./testcollection/ are only stored to ease creation of database files for any future importing targets, or modification of current database files in case of schema changes, etc. These files are tiny (< the block size) mp3 tracks containing various id3v2 tags.
When creating a new database file, in addition to importing files from ./testcollection/ , please follow the directions outlined in ../TestImporterBase.h
