Console::TestRunner supports an io parameter to send output to an IO object, but Autorunner has no way to control it!

test/unit/ui/console/testrunner.rb contains the Test::Unit::UI::Console::TestRunnner class with a 3-parm initalizer
But Test::Unit::AutoRunner has no option to specify an alternative destination for io,
and even if it did, run is only called with 2 parameters!

I need to redirect test output to a file, and the console testrunner supports this, but the autorunner machinery doesn't use it. The fix is simple, but requires 2 files to change.

Console::TestRunner defines a 3rd, optional 'io' parameter, obviously meant to support redirecting output to an arbitrary io object.
The autorunner machinery is fine for me (I don't need a whole custom autorunner), but needs an option to direct output elsewhere (e.g. a file). I added a new attribute, output_io, set via the new --output option, and the critical change
def run
...
result.run(@suite, @output_level).passed?
end
to
result.run(@suite, @output_level, @output_io).passed?

But run calls the TestRunner thru Test::Unit::UI::run() - we need to alter test\unit\ui\testrunnerutilities.rb to accept this 3rd parm and pass it along, i.e. change
def run(suite, output_level=NORMAL)
return new(suite, output_level).start
end
to
def run(suite, output_level=NORMAL, io=STDOUT)
return new(suite, output_level, io).start
end

I've attached modified files, diff against 1.8.6 to see the exact changes.

I don't see how Console TestRunner's io parameter is accessible - w/o writing a custom AutoRunner, just to control this one option. A heavyweight solution with ugly maintenance and sync implications. But if I've missed something, by all means, please point it out.

I don't maintain test/unit.

You might prefer to try minitest, which already supports an io object.
