I wrote to the post of Andrea (a dev from the Copilot team) about their 800K LoC: 128 PRs, shipped incrementally. Existing end-to-end tests ran against the new code at every step.
Total: ~1,301,378 lines of Rust.
Production: 832,378
Unit tests: ~469,000
Combined: ~1.30 million lines
On top of the 832K LoC are mostly tests she answered:
> Yeap, 832,378 lines of production Rust. the +800K number is production only; unit tests are another +469K on top.
