Sorry, I'm not following. I'm saying the article says less than 30% of repos scanned used Unittest. That was in response to you seeming to say that most projects would choose Unittest.
Oh, I see, you misunderstood me. I did not claim that “most projects would choose Unittest”. I claimed that for many projects, it would be wise to consider using unittest instead of, for example, pytest, as a way of minimizing usage of third-party modules.
