In unit.rb with “ruby 1.8.6 (2007-03-13 patchlevel 0) [i386-mswin32]”

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

if Test::Unit.run is set as false the autorunner will run, if it is set  
as  
true the autorunner will not run.  
I don’t think this was the intention.

It should read as  
unless $! && ! Test::Unit.run?

or (more readable).  
if Test::Unit.run? && $!.nil?

Unless I am missing somethig…

Thanks  
Nasir

not a bug… just bad English. It should be #ran?, not #run?.

Well, if you see a few lines above that in unit.rb

module Unit  
# If set to false Test::Unit will not automatically run at exit.  
def self.run=(flag)  
@run = flag  
end

Now to me this reads as if you set the flag to true the tests will run  
on  
exit and if set to false the tests will not run on exit.

This is obviously not what will happen when  
at\_exit do  
unless $! || Test::Unit.run?  
exit Test::Unit::AutoRunner.run  
end  
end

is executed, but the exact opposite.

Agree. This is how I am using it now.
