·The mock print stream overwrites only one println() function, which makes
it susceptible to changes in the sink. It is better to use a regular
PrintStream that prints to a StringWriter to collect all contents.·
Hi @StephanEwen
If I change this how can I get the printed message?
Since I use System.setOut(stream); to solve this before.
