Looking from an outside perspective I would agree, but in practice we don't actually know what this dataset is, so several things rows per test may make sense in the context of this stage of the data processing.
Or at least how often my peers do that. Obviously all of my systems and code are perfect.
This also amazes me, especially the whining about other people's code from developers. Truely believing that they would do it better. I've even seen inherited code posted to be ridiculed/shamed/bashed in some slacks and subreddits.
