[Testing Concurrent Code with `testing/synctest`](https://go.dev/blog/synctest) — Concurrency is one of Go’s natural strengths, but testing heavily concurrent programs can be tricky. Go 1.24 introduces a new (though experimental and hidden behind an environment variable) package for testing code involving time or concurrency. The Go team wants you to have a play and send in your feedback.
