Congratulations, you discovered that generating code is only part of software development process. If you don't understand what the code is actually doing, good luck maintaining it. If it's never reviewed, how do you know these tests even test anything? Because they say "test passed"? I can write you a script that prints "test passed" a billion times - would you believe it is a billion unit tests? If you didn't review them, you don't have tests. You have a pile of code that looks like tests. And "it takes too long to review" is not an excuse - it's like saying "it's too hard to make a car, so I just took a cardboard box, wrote FERRARI on it and sit inside it making car noises". Fine, but it's not a car. It's just pretending. If it's not properly verified, what you have is not tests, it's just pretending.
