No idea but coding against unit tests, rather than testing every change on a running app, should help avoid that frustration.

While I do not deny the value of automated tests, the ability to do incremental, live updates when rapidly prototyping is indispensable.

Unit tests doesn't help when exploring the behavior of the app. Working in a live environment is wonderful for debugging.
