在 JUnit 5 中使用 MockMvc 进行测试时出现“符号未找到”错误

Question

下面测试源码中的status()函数出现错误。由于源代码中没有 status() 函数，因此出现错误是很自然的。但是，我没有在书籍或互联网上的源代码中看到创建单独的函数。调用 status() 函数需要什么？

package kr.jhansol.blog.controller;

import com.fasterxml.jackson.databind.ObjectMapper;
import kr.jhansol.blog.dto.AddArticleRequest;
import kr.jhansol.blog.repository.BlogRepository;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.DisplayName;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.http.MediaType;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.ResultActions;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;

import static org.junit.jupiter.api.Assertions.*;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.post;

@SpringBootTest
@AutoConfigureMockMvc
class BlogApiControllerTest {
    @Autowired
    protected MockMvc mockMvc;

    @Autowired
    protected ObjectMapper objectMapper;

    @Autowired
    private WebApplicationContext context;

    @Autowired
    BlogRepository blogRepository;

    @BeforeEach
    public void mockMvcSetUp() {
        this.mockMvc = MockMvcBuilders.webAppContextSetup(context).build();
        blogRepository.deleteAll();
    }

    @DisplayName("Blog write test")
    @Test
    public void addArticle() throws Exception {
        final String url = "/api/articles";
        final String title = "test";
        final String content = "This is test.";
        final AddArticleRequest request = new AddArticleRequest(title, content);
        final String requestBody = objectMapper.writeValueAsString(request);

        ResultActions result = mockMvc.perform(post(url)
                .contentType(MediaType.APPLICATION_JSON_VALUE)
                .content(requestBody));

        result.andExpect(status().isCreated());
    }
}

执行上述代码时，输出以下错误。

D:\spring_projects\blog\src\test\java\kr\jhansol\blog\controller\BlogApiControllerTest.java:55: error: cannot find symbol
        result.andExpect(status().isCreated());
                         ^
  symbol:   method status()
  location: class BlogApiControllerTest

解决了。 我将下面的代码添加到上面源代码的顶部。

导入静态org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;
