Ever fought with Go tests that randomly pass or fail because of goroutines, timers, and real time?
In my new article, I explain how synctest creates a synthetic, fully controlled bubble for your tests — giving you deterministic, instant, and reliable results.
You’ll see:
✅ Debouncers without random failures
✅ Backoff retries in zero real time
✅ Cache TTLs that expire exactly when expected
✅ Heartbeat monitors and rate limiters that test consistently
