Catch regressions early to make them easier to find. I’ve seen too many problems that took so long to find after they were allowed in the tree due to lack of tests. Have tests and CI/CQ as soon as you can.

• Projects like Chrome/ChromeOS and Fuchsia use both, based on luci https://luci-scheduler.appspot.com/jobs/fuchsia/ci-fuchsia-x64-release
• Developers are supposed to do their own testing first and before they can send a change for review, it is run by CQ, for which fuchsia runs lots of tests in emulated environments (qemu in google cloud), and actual hardware of different types (CPU and peripherals)

CQ/CI (Commit Queue, Continuous Integration)
