Debug mode much needed as a developer to debug

There are test cases which gets failed in parallel, it gets difiicult to debug if output is suppresed on the console. We need that functionality to use it. I agree it adds bvalue as it enabled me to run tests in parallel. But giving output on screen will more or less help in debugging even if it is printing on screen at different timings due to speed of execution. It will be a pie on the cake.
