【问题描述】：

我想在我的 sprint 启动应用程序中添加端到端测试，并按照本教程进行操作：https://reflectoring.io/spring-boot-web-controller-test/

package com.example.petstore.backend.api.implementation;

import com.example.petstore.backend.api.model.Pet;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.WebMvcTest;
import org.springframework.test.context.junit.jupiter.SpringExtension;
import org.springframework.test.web.servlet.MockMvc;

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

@ExtendWith(SpringExtension.class)
@WebMvcTest(controllers = PetController.class)
public class PetControllerE2E 

    @Autowired
    private MockMvc mockMvc;

    @Autowired
    private ObjectMapper objectMapper;
    
    @Test
    void whenValidInput_thenReturns200() throws Exception 
        Pet pet = new Pet().id(0L);

        mockMvc.perform(post("/pet")
            .contentType("application/json")
            .content(objectMapper.writeValueAsString(pet)))
            .andExpect(status().isOk());
    

现在如果我运行这个测试，我会得到：

Execution failed for task ':test'.

我的 gradle 文件是：

plugins 
    id 'org.springframework.boot' version '2.3.4.RELEASE'
    id 'io.spring.dependency-management' version '1.0.10.RELEASE'
    id 'java'

test 
    useJUnitPlatform()


...

所以看起来org/junit/jupiter/api/extension/ScriptEvaluationException 丢失了，因为我忘记了依赖项。

但是，该类应该是 https://junit.org/junit5/docs/5.4.0/api/org/junit/jupiter/api/extension/ScriptEvaluationException.html 的一部分，因此包含在 testCompile 'org.junit.jupiter:junit-jupiter:5.4.0'.

为什么会出现这个错误？我该如何解决这个问题？

【参考方案1】：

使用 testCompile 'org.junit.jupiter:junit-jupiter:5.4.0' 有效。
