I don't know. Why does a language model do anything? The "test" was a print statement, not a unit test. There wasn't a failure message. It had to read the output and compare it to the expected value I gave it. It claimed it got a different result. I guess it didn't really read the result because it strongly expected something else? If you use an assertEquals() that loudly complains, maybe it's less likely to do this? I haven't seen it ignore stack traces.
