Question

我正在尝试使用@WithMockUser测试来测试我的CommentController，但似乎它找不到用户（因为用户id（author_id）为null）或注释的内容。我不确定测试是否以正确的方式完成（我仍然是初学者），但我想要实现的是可能的最高代码覆盖率，但我之前的测试不包括搜索经过身份验证的用户和创建的评论：

mockMvc.perform(get("/post/3/comment").with(authentication(authentication)).content("content")).andExpect(status().is3xxRedirection()).andExpect(view().name("redirect:/post/{id}/"));

package com.paulthemenace.blog.controllers;
import com.paulthemenace.blog.models.Comment;
import com.paulthemenace.blog.models.User;
import com.paulthemenace.blog.repositories.UserRepository;
import com.paulthemenace.blog.services.CommentService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.Authentication;
import 
org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class CommentController {

@Autowired
private UserRepository userRepo;
@Autowired
private CommentService comSrv;

@RequestMapping(value = "/post/{id}/comment")
public String comment(@PathVariable("id") Long id, 
@ModelAttribute("comment") Comment comment, Model model) throws 
Exception {

    Authentication auth = 
SecurityContextHolder.getContext().getAuthentication();

    if (auth != null) {

        String name = auth.getName();
        User currentUser = userRepo.findByUsername(name);

        if (comment.getContent() != "") {

            comment.setAuthor(currentUser);
            comSrv.create(comment);

        }

    }

    return "redirect:/post/{id}/";
}

}

CommentControllerTest

    import com.paulthemenace.blog.controllers.CommentController;
    import org.junit.Before;
    import org.junit.Test;
    import org.junit.runner.RunWith;

    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.boot.test.context.SpringBootTest;

    import 
    org.springframework.security.test.context.support.WithMockUser;

    import org.springframework.test.context.junit4.SpringRunner;
    import org.springframework.test.context.web.WebAppConfiguration;
    import org.springframework.test.web.servlet.MockMvc;


    import static org.assertj.core.api.Assertions.assertThat;
    import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.post;
    import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;
    import static org.springframework.test.web.servlet.setup.MockMvcBuilders.standaloneSetup;

    @SpringBootTest
    @RunWith(SpringRunner.class)
    @WebAppConfiguration

    public class CommentControllerTest {


    @Autowired
    private CommentController commentController;

    private MockMvc mockMvc;

    @Before
    public void setup() {
    this.mockMvc = standaloneSetup(commentController).build();
    }

    @Test
    public void controllerIsNotNull() {
    assertThat(commentController).isNotNull();
    }


   @Test
   @WithMockUser(username = "user", password = "user")
   public void checkIfContainsAuthenticatedUserAndCreatesComment()       
   throws Exception {

    mockMvc.perform(post("/post/3/comment")
                .content("comment                 
   content")).andExpect(status().is3xxRedirection())
                .andExpect(view().name("redirect:/post/{id}/"));


        }


    }

测试是否正确？我希望这个项目能够在测试驱动的开发中完成，但我失败了。我搜索了关于Spring Boot测试的资源，但没有一个帮助我解决这个问题。

感谢您的帮助！

感谢Barath发送的链接，我设法修复它并在该控制器上获得100％的代码覆盖率：

    @Test
@WithMockUser(username = "sure", password = "sure")
public void checkIfContainsAuthenticatedUserAndCreatesComment() throws Exception {

        Authentication auth = SecurityContextHolder.getContext().getAuthentication();
    MockHttpServletRequestBuilder request = MockMvcRequestBuilders.post("/post/3/comment");

    Comment com = new Comment();
    String name = auth.getName();

    User currentUser = userRepo.findByUsername(name);

    com.setAuthor(currentUser);
    com.setContent("ahdsf");

    request.flashAttr("comment", com);


    mockMvc.perform(request).andExpect(status().is3xxRedirection())
                .andExpect(view().name("redirect:/post/{id}/"));


}

什么是我的愚蠢，我没有注意到它仍在从MYSQL读取用户，所以我不得不从表中插入一个“真正的”用户。再次感谢！

Spring Boot测试 - 使用@WithMockUser
