Constant MissingServletRequestParameterException

标签: java testing spring-boot mockito

出于某种原因,我不断收到错误消息:

  

MissingServletRequestParameterException:必需的String []参数   “ids”不存在

我有一个可以从/products?ids=["item1", "item2"]

调用的端点

我的集成测试类看起来像这样:

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.InjectMocks;
import org.mockito.runners.MockitoJUnitRunner;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

@RunWith(MockitoJUnitRunner.class)
public class ProductControllerTest {

    private MockMvc mockMvc;

    @InjectMocks
    private ProductController controller;

    @Before
    public void setup() {
        mockMvc = MockMvcBuilders.standaloneSetup(controller).build();
    }

    @Test
    public void shouldFetchProducts() throws Exception {
        mockMvc.perform(get("/products")
                .param("ids[]", "[\"item\"]"))
                .andExpect(status().is2xxSuccessful());
    }
}

我尝试了什么:

  1. 使用 param

    @Test
    public void shouldFetchProducts() throws Exception {
        mockMvc.perform(get("/products")
                .param("ids[]", "[\"item\"]"))
                .andExpect(status().is2xxSuccessful());
    }
    
  2. 使用 requestAttr

    @Test
    public void shouldFetchProducts() throws Exception {
        mockMvc.perform(get("/products")
            .requestAttr("ids[]", "[\"item\"]"))
            .andExpect(status().is2xxSuccessful());
    }
    
  3. 我做错了什么?

你试过吗

@Test
public void shouldFetchProducts() throws Exception {
    mockMvc.perform(get("/products")
            .param("ids", "item1", "item2"))
            .andExpect(status().is2xxSuccessful());
}

可以找到param的文档here

尝试使用MultiValueMap

MultiValueMap<String, String> params = new LinkedMultiValueMap<>();
params.add("ids", "item1");
params.add("ids", "item2");

现在,当您编写测试用例时,请使用以下命令:

mockMvc.perform(get("/products")
            .params(params))
            .andExpect(status().is2xxSuccessful());
