Hello,

Not sure if anyone’s noticed this before, but there’s bug in  
Test::Unit’s unit.rb :

at\_exit do  
unless $! || Test::Unit.run?  
exit Test::Unit::AutoRunner.run  
end  
end

Can you spot the bug? You have to do

Test::Unit.run = true

in order to disable the AutoRunner.

George

or just don’t include ‘test/unit’.
