You don’t, you get it to write both the code and the tests. And you read both of them yourself. And you run them in a debugger to verify they do what you expect.
Yeah, that’s half the work of “normal coding” but it’s also half the work. Which is a pretty awesome boost to productivity.
But where it really boosts your productivity is with APIs that you aren’t very familiar with. I used to spend half my day googling for things. Now I can’t remember the last time I googled for something work related. Last week maybe?

You might have to rewrite all of it. The code and the tests.
Hell even the structure/outline it took might not be correct.
