@Test public void deleteTest() throws Exception { Comment c = new Comment(); c.setArticleID(-1L); c.setType(true); c.setAuthorID(2L); c.setDate(new Date()); c.setPid(-1L); commentMapper.insert(c); Comment comment = commentMapper.getLastestComment(); long id = comment.getId(); assertNotEquals(0, id); String token = userLogin(); mockMvc.perform(delete("/user/comment/del?id=" + id).header("Authorization", token)).andDo(result -> { JSONObject object = JSONObject.fromObject(result.getResponse().getContentAsString()); assertEquals(SUCCESS.getCode(), object.getInt(Code)); assertTrue(object.getBoolean(Result)); }); mockMvc.perform(delete("/user/comment/del?id=" + id).header("Authorization", token)).andDo(result -> { JSONObject object = JSONObject.fromObject(result.getResponse().getContentAsString()); assertEquals(COMMENT_NOT_EXIST.getCode(), object.getInt(Code)); }); }
