### Question:
Assert { public static <T> T unsupportedOperation() { unsupportedOperation(null, (Object[]) null); return null; }  static T assertNotNull(T object); static T assertNotNull(T object, String message, Object...args); static T assertNotNull(T object, ExceptionType exceptionType, String message, Object...args); static T assertNull(T object); static T assertNull(T object, String message, Object...args); static T assertNull(T object, ExceptionType exceptionType, String message, Object...args); static void assertTrue(boolean expression); static void assertTrue(boolean expression, String message, Object...args); static void assertTrue(boolean expression, ExceptionType exceptionType, String message, Object...args); static T unreachableCode(); static T unreachableCode(String message, Object...args); static T unexpectedException(Throwable e); static T unexpectedException(Throwable e, String message, Object...args); static T fail(); static T fail(String message, Object...args); static T unsupportedOperation(); static T unsupportedOperation(String message, Object...args);  }### Answer:
@Test public void unsupportedOperation() { try { Assert.unsupportedOperation(); } catch (UnsupportedOperationException e) { assertThat(e, exception(UnsupportedOperationException.class, DEFAULT_HEADER, "unsupported")); } try { Assert.unsupportedOperation(MESSAGE); } catch (UnsupportedOperationException e) { assertThat(e, exception(UnsupportedOperationException.class, MESSAGE)); } try { Assert.unsupportedOperation(MESSAGE, 1); } catch (UnsupportedOperationException e) { assertThat(e, exception(UnsupportedOperationException.class, MESSAGE_1)); } }
