📢 Working with Go's test cache on CI
🎤 Björn Andersson - Principal Engineer, foodpanda
Do you know what you can cache test results on CI so you don't have to re-run tests for code that hasn't changed between CI runs? Are you also aware that this could mean black box integration tests that depend on running services can get cached because Go doesn't know they call other services, and therefore you might have a false-positive and let buggy code out? This is a walkthrough of how Go's build cache works for tests. I'll show you how to design your test suite to benefit from caching and make sure your tests that absolutely cannot be cached aren't.
