Everyone tests in production. Some people also test before production!
Some people try to NOT test in production, but everyone does test in prod in a very real sense because dependencies and environments are different in prod.
I think the question was "Do you INTENTIONALLY test in production"
Yeah. What some people mean by “we don’t test in prod” is that we have very high confidence in all code before it goes to prod. And good for them! But what most people mean is “code goes from zero to affecting all users and developers have little or no access to data about how that’s going.” Bad. No matter how many unit tests you have.
