No, that's not true. But that's how I felt after reading it. An Upheavel was wonderfully written, but ended rather abruptly. I suppose Chekhov just had an idea he wanted to put on paper, even if it never developed into a full novel. Chekhov is known for his extensive writing. In a little over 20 years he wrote hundreds of short stories. So if any of them feel unfinished we shouldn't blame him. Just be happy we get a taste of his wonderful writing.An Upheaval is a perfect example of that. You are quickly drawn into the story of a young governess who has to choose between harsh treatment by her mistress or returning to a simpler, if poorer, way of life. She is an instant heroine, and instantly likable. That shows great talent for Anton Chekhov to have a character grab readers in such a short amount of time.
