org.apache.uima.fit.testing.util.HideOutput

public class HideOutput
extends Object

This class provides a way to hide output sent to System.out and System.err. This may be useful when testing code that creates a lot of noisy output that can be ignored for testing purposes. This class works by redirecting System.out and System.err - note that this may have unintended side effects if you are not careful to call restoreOutput() after the noisy code. Intended usage: HideOutput hider = new HideOutput(); try { ... noisy code ... } finally { hider.restoreOutput(); }
