RunningNode { static String getRunningTaskNodePath(final String taskMetaInfo) { return String.format(RUNNING_TASK, TaskContext.MetaInfo.from(taskMetaInfo).getJobName(), taskMetaInfo); }    }### Answer:
@Test public void assertGetRunningTaskNodePath() { String nodePath = TaskNode.builder().build().getTaskNodePath(); Assert.assertThat(RunningNode.getRunningTaskNodePath(nodePath), Is.is("/state/running/test_job/" + nodePath)); }
