I find that doing all of this tends to actually save time overall it's just that the up front investment is high and the payoff is realized over a long time.

Most software teams seem to prefer higher ongoing costs if it comes with quick wins to up front investment.

Those are the age-old arguments against TDD. Every team will have to analyze the value proposition in their context to see if the return is worth the investment.
