In your experience does Unit testing actually speed up development?

Question

we've used unit testing at our office and it helps in writing safer code and also in creating code that is easier to maintain. have any of you had experience that writing unit tests actually speeds up the process of writing code?

Answer 1

I think it helps in creating your code faster when you write your test before your real code.
This way you are focused on one problem and will finish it faster than first write code then test.
My opinion.
