I don't want to hijack @vidhya's thread which seems focused on platforms enabling app team testing. But I'm curious about the other angle of testing/automated testing in platform eng....how we test our platforms 👀 IaC testing has improved much slower than I had expected over the last 10 years or so. Or maybe not? And platforms are more than just IaC, it's business processes and upgrades and things. How are people testing their platforms themselves?
