Mockito测试框架如何对controller层进行测试

public @ResponseBody
AfPrr shortApprove(@RequestBody AfPrr afPrr, HttpServletRequest request) {
iAfPrrService.shortApprove(afPrr, SessionUtils.getCurUser(request));
return afPrr;
}
现在需要对这个controller方法进行测试
以下是我测试的，不知道怎么传HttpServletRequest 参数过去

 @Test
    public void shortApprove() throws Exception {
        AfPrr afPrr = new AfPrr();
        afPrr.setScmPId(1L);
        afPrr.setLimit(10);
        afPrr.setOffset(1);
        List<AfPrr> list = Arrays.asList(afPrr);
        String s = JSONObject.toJSONString(list);

        this.mvc.perform(MockMvcRequestBuilders.post("/afPrr/shortApprove")
                .contentType(MediaType.APPLICATION_JSON)
                .content(s))
                .andReturn();
    }

```

好像是调用.session方法吧
