Recently I've begun writing tests which need to do things in several threads. I'm curious as to what approaches other people have taken when doing this, and whether any of the CL test frameworks address this situation specifically.

I don't have much experience with lparallel yet, but I think it provides the building blocks you're looking for.

• detecting, handling, and reporting conditions that are raised in threads

other than the main test/reporting thread

http://lparallel.org/handling/

• ensuring that the main test thread waits for the other threads before

checking for the correct results (and before returning)

http://lparallel.org/promises/ (or possibly other constructs depending on your concrete use case)

• forcing things in different threads to happen at the same time (I've been

using SBCL's timers for this)

Queues or channels might help here.
