Thanks for adding these tests! Do you want me to merge and close this now or leave it open? Do you want to add any more tests?

[ws233]

I'm in progress with some more tests. But I think it's better to spread them to different small commits. Otherwise it will be to big and diffucalt to understand.

That's enough so far.

[ws233]

Done. You should also be aware, that G8Tesseract initializer will now return nil, if it's called with cashes related datapath and there is niegther tessdata folder in the Cashes directory nor App bundle. That means it first tries to copy tessdata from the App bundle to Caches folder and start from there, if there is no tessdata folder yet. In the case there is also no tessdata in the App bundle it cannot copy anything and cannot start successfully. Therefore returns nil.
