It is possible to do it with Rexbug! Here's an example:

iex(1)> s = self()  
#PID<0.193.0>
iex(2)> proc = Process.spawn(fn ->                    
...(2)>   receive do                             
...(2)>     anything -> send(s, {:got, anything})
...(2)>   end                                    
...(2)> end, [])
iex(3)> Rexbug.start([:send, :receive], procs: proc, time: 60_000) 
{1, 0}
iex(4)> send(proc, :foo)
:foo
        
# 18:31:08 #PID<0.208.0> (:dead)
# <<< :foo
        
# 18:31:08 #PID<0.208.0> (:dead)
# #PID<0.193.0> IEx.Evaluator.init/4 <<< {:got, :foo}
iex(5)> flush()
{:got, :foo}
:ok
redbug done, timeout - 2

I'm probably going to add this example to the README

This trick is handy - must share
