Vyacheslav, I have made a simple ranking for your data for highlighting classes which more than other needs testing.
Please take a look at the list which I have done (36 classes): https://drive.google.com/file/d/1RJrtnN77MeEWLTShFzqaLInCdOSb9WdC/view?usp=sharing Below you can read how did it in details: First I have removed all small classes (less than 200 lines), classes with more than 80% coverage, and with 0% (too strange result). After that, I have extracted subset which dominates other classes by two parameters: coverage and complexity. It means all other classes have not less coverage and not greater complexity, and also better at least at one of these parameters. Finally, I have sorted this list by value "coverage/complexity".
