I upvoted the first option then realized I needed to upvote all of them. I have and will continue to confirm to each as the situation calls and allows.
Yeah many times when you are 'spiking' and idea you can work through a simple small example fastest without testing. I agree when you are quickly just trying to see if something is possible testing will slow you down, and isn't worth the benefits of TDD.
Then when I start to integrate that solution into real production code I go back and add some tests. (mostly integration tests)
