将空数组参数传递给 MockHttpServletRequestBuilder 参数方法

Question

我正在使用 MockHttpServletRequestBuilder 创建我的框架测试请求。我拥有的请求参数之一是字符串数组。对于我的测试，我想通过在我的请求中传递一个空数组来进行测试。但是，MockHttpServletRequestBuilder.addToMultiValueMap 中的断言不允许我传递 null 或空值。

这是我收到的错误正文：

java.lang.IllegalArgumentException: 'values' must not be empty
at org.springframework.util.Assert.notEmpty(Assert.java:214)
at org.springframework.test.web.servlet.request.MockHttpServletRequestBuilder.addToMultiValueMap(MockHttpServletRequestBuilder.java:698)
at org.springframework.test.web.servlet.request.MockHttpServletRequestBuilder.param(MockHttpServletRequestBuilder.java:153)
at MyMockApiRequests.queryPath(MockJdbcApiRequests.java:105)

有没有其他方法可以测试这种情况？

我认为将您的值设置为空字符串是可行的。

我的控制器

@RequestMapping(value = "/admin/config", method = RequestMethod.GET)
public List<TdConfig> getTdConfigs(@RequestParam(required = false) List<String> names) {
    return tdAdminService.getTdConfigs(names);
}

我的 Mockito

MultiValueMap<String, String> params = new LinkedMultiValueMap<>();
    params.add("names", "");
    MockHttpServletRequestBuilder request = get("/admin/config")
            .params(params)
            .accept(MediaType.APPLICATION_JSON);

    mockMvc.perform(request)
            .andExpect(MockMvcResultMatchers.status().isOk())
            .andDo(print());

请求的打印输出：

MockHttpServletRequest:
      HTTP Method = GET
      Request URI = /admin/config
       Parameters = {names=[]}
          Headers = {Accept=[application/json]}
