A possible FAQ question

[davecb]

I have a program that communicated between threads via a channel.
To test an error condition in the receiver, I wrote

Convey("Passing bad operations to send should panic worker", func(c C) {
	// the panic happens in worker(), not send,
	c.So(func() { r.send(-1, Err, 1) }, ShouldPanic)
})

r.send sends an illegal -1, the worker thread duly panics, and send returns without error, rather than reporting that a different thread panicked.

How do I construct a test that detects a panic in another thread? Can I?
