### Question:
SnapshotService { public List<Snapshot> getByPath(String path, String cluster, int offset, int limit) throws ShepherException { return snapshotBiz.listByPath(path, cluster, offset, limit); }  List<Snapshot> getByPath(String path, String cluster, int offset, int limit); Snapshot getById(long id);  }### Answer:
@Test public void testGetByPath() throws Exception { String path = "/test/test2"; String cluster = "local_test"; int offset = 0; int limit = 20; List<Snapshot> snapshots = snapshotService.getByPath(path, cluster, offset, limit); Assert.assertNotNull(snapshots); Assert.assertEquals(2, snapshots.size()); }
