For a brief overview of how software engineering is done at Google, see my paper "Software Engineering at Google" <https://arxiv.org/abs/1702.01715>, and with regards to architecture, see in particular sections 2.9, 2…
Untangle one dependency at a time.
It's common for code at Google to be rewritten without reusing most of the existing tests -- instead, new tests are written for the new code. Yes, this risks not understanding edge cases. But not all of those edge cases…
That's actually an error in the paper -- JavaScript is now an officially approved programming language at Google.
