For my money, certain types of software shouldn't have tests, too much planning, or any maintenance whatsoever
Prototypes (start ups) rarely have the luxury of "getting it right", their actual goal is "getting it out there FAST to capture the market (and have it working enough to keep the market)"
(Some - apologies but I'm not a game dev enough to be able to say what types this applies to) Game devs - they're more or less build it, ship it, and be done with it, players tend to be forgiving of most bugs, and they move on to the next shiny thing long before it's time to fix all the things.
Once the product has traction in the market, and you have paying customers, then it's time to deal with the load (scale up) and bugs, I recall reading somewhere that it's probably best to drop the start up team, they did their job (and are now free to move on to the next brilliant idea), and replace them with a scale up team, who will do the planning, architecting, and preparation for the long term life of the software.
I think that that approach would have worked for Facebook (for example) they had their PHP prototype that captured the market very quickly, and (IMO) they should have moved through to a scale up team (who could have used the original code as a facade, strangling it to replace it with something funky (Java/C++ would have been what was available at the time, but Go would be what I would suggest now)
