        if (handler.key != null && !"-confKey".equals(cmd.getName())) {
            // Add the key to the conf and ensure tool returns the right value
            String[] args = { cmd.getName() };
            conf.set(handler.key, "value");
            assertTrue(runTool(conf, args, true).contains("value"));
