If you have unit tests that generate xml more specifically if they have CDATA sections, it breaks the outputed junit xml so you can't use it in another tool like hudson. The easiest solution for me was to just xml escape the output, maybe have an option for this?

The fix is in test_suite.rb
change

        builder.cdata! self.stdout

to

        builder.cdata! self.stdout.to_xs

and

       builder.cdata! self.stderr

to

        builder.cdata! self.stderr.to_xs
