org.apache.uima.fit.testing.util.HideOutput
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 {@link #restoreOutput()} after the noisy code.Intended usage: HideOutput hider = new HideOutput(); try { ... noisy code ... } finally { hider.restoreOutput(); }

            SofaAwareAnnotator.class, typeSystemDescription);
    AnalysisEngine engine = AnalysisEngineFactory.createEngine(description, "myView");
    HideOutput hider = new HideOutput();
    engine.process(jCas);
    hider.restoreOutput();
