Paper author here. As someone already mentioned, the suites were made by picking a random subset of the test cases written by the developers, not by using a suite generation tool. Now, our method is arguably not 100% realistic either, because in practice different parts of the program will have different coverage. Some kind of weighted random sampling might make suites that are a bit closer to "real" suites. I've been thinking about looking into that. I think our suites are realistic enough to make the results worthwhile, though.
