Testing in Go: from basic to advanced
summary
Go testing techniques with runnable code: how to use t.Helper and t.Run subtests, table-driven tests and the common loop-variable bug that makes parallel subtests share the same value, and how that turned three 1s runs into 3s. Shows using -race to detect data races, build tags like // +build integration with -short to skip slow integration tests, how to implement global setup/teardown with TestMain, and forcing fresh runs with -count to bypass cached results.
