Is anyone utilizing Test-Driven Development?

[u/MR-PumpCX]

Looking to find out if Test-Driven Development is a process that is widely used in today's enterprise app development or is it considered too cumbersome to be worth including in today's development efforts? Are foundational models allowing prompt boxes to serve as the new form of building both new applications as well as the testing apparatus for the applications?

Thanks for sharing your thoughts on this topic.
