### Question:
RollbackCommand extends RollbackListCommand implements CommandSuccessIndicator { void setRollbackCommandConf(RollbackCommandConf rollbackCommandConf) { this.rollbackCommandConf = rollbackCommandConf; } RollbackCommand(EnvSettings envSettings); boolean isSuccess();  }### Answer:
@Test public void testRollbackCommandSingle() throws Exception { command.setRollbackCommandConf(new RollbackCommandConf(RollbackCommandConf.Action.SINGLE, "010.patch1")); command.execute(); Assert.assertArrayEquals(new Integer[]{3}, dbValues()); }
@Test public void testRollbackCommandStopOn() throws Exception { command.setRollbackCommandConf(new RollbackCommandConf(RollbackCommandConf.Action.STOP_ON, "010.patch1")); command.execute(); Assert.assertArrayEquals(new Integer[]{ }, dbValues()); }
