How We Actually Started
Back in 2019, I was consulting for a logistics company in Kaohsiung. Their new warehouse management system was supposed to sync with their existing ERP — should have been straightforward. Three months later, they were still manually entering data twice because the APIs kept timing out under real-world load.
That's when it clicked. Everyone was testing integrations like they worked in isolation, but real systems are messy. They have peak loads, network hiccups, and edge cases that nobody thinks about until they break everything at 2 AM on a Tuesday.
We built our first testing framework specifically for that logistics client. It simulated their actual traffic patterns, tested failure scenarios, and caught problems before they hit production. The difference was night and day.
