/**
* Evil test-coverage cheat, we parse a bunch of docs from tika
* so that we have a nice grab-bag variety, and assert some content
* comes back and no exception.
* Parse sample tika documents and assert the contents has not changed according to previously recorded checksums.
* Uncaught changes to tika parsing could potentially pose bwc issues.
* Note: In some cases tika will access a user's locale to inform the parsing of a file.
* The checksums of these files are left empty, and we only validate that parsed content is not null.
