Thanks for the reply Jarkko, Yes I can work around it. The scenario is that I want to see a message correctly passed: http://github.com/timothypratley/strive/blob/cef5a3a9ea18159f866fe6c94603b704daba1ba8/clj/timothypratley/test-messenger.clj It is useful (tempting?) in this case to be able to check something on a thread, but I can save the value and check it later to avoid doing so.
Regarding futures not raising exceptions, this is actually completely independent of test. From experimentation, exceptions on futures are only reported if the future is @ examined (presumably by design). So I think my options are to wrap long running futures in a try/catch/ report or use a normal Thread. Regards Tim.
