Unit Tests are a god send when you have good coverage on a legacy large project.

Refactor code, and it gives you that much more confidence you have not broken anything.

They're seriously useful mid-later stages of a project, which is probably why startups devs aren't doing them...

I think what they are saying is the kind of tests they see in a corporate environment are not the kind that add any value to the refactoring process (or worse, inhibit it).
