### Question:
AbstractAnnotation { @SuppressWarnings("unchecked") public T getAnnotation() { return (T) this.annotation.deepCopy(); } @SuppressWarnings("unchecked")  AbstractAnnotation(T annotation); abstract boolean isValid(); boolean validate(Communication c); @SuppressWarnings("unchecked") T getAnnotation();  }### Answer:
@Test public void testGetAnnotation() { AnnotationMetadata md = new AnnotationMetadata() .setTool("Test") .setTimestamp(System.currentTimeMillis()); ValidatableMetadata vmd = new ValidatableMetadata(md); assertEquals("Tools should be equal.", md.getTool(), vmd.getAnnotation().getTool()); md.setTool("Test-again"); assertNotEquals("After change to seed object, tools should not be equal.", md.getTool(), vmd.getAnnotation().getTool()); String test = "Test-thrice"; vmd.getAnnotation().setTool(test); assertNotEquals("After change to fetched object, tools should not be equal.", test, vmd.getAnnotation().getTool()); }
