Question

我们认为Spring Rest Doc非常适合记录rest api。但它基于Spring MVC Test，我们无法弄清楚如何在我的grails应用程序中使用Spring MVC Test（Grails 3.0.5）。

我尝试使用配置类（使用@Configuration和@ComponentScan）将grails组件扫描到测试上下文中，但似乎没有加载任何内容（在向{执行http请求时） {1}}，它得到了404）。

我还尝试直接配置grails控制器，并出现运行时错误。

无法自动装配字段：private reactor.bus.EventBus

我还尝试在测试类中添加mockmvc（来自grails），但收到了同样的错误。

请帮忙。

以下是一些代码示例。我尝试的是将配置类或类位置或grails控制器添加到下面的测试类的ContextConfiguration。测试类本身基本上遵循@Integration引用。

spring rest doc

配置类（没用）：

import org.junit.Before;
import org.junit.Rule;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.context.WebApplicationContext;
import org.springframework.restdocs.RestDocumentation;
import static org.springframework.restdocs.mockmvc.MockMvcRestDocumentation.documentationConfiguration;

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration
//TODO how to scan Grails components into the test context
public class QuestionRestSpec {
@Rule
public final RestDocumentation restDocumentation = new RestDocumentation("build/generated-snippets");
@Autowired
private WebApplicationContext context;

private MockMvc mockMvc;

@Before
public void setUp() {
    this.mockMvc = MockMvcBuilders.webAppContextSetup(context)
            .apply(documentationConfiguration(this.restDocumentation))
            .build();
}
}

不幸的是，似乎没有可能将MockMvc与Grails一起使用。致电MockMvc.perform失败：

Spring REST Docs 1.1 will hopefully add support for REST Assured。这消除了对MockMvc的需求，而是允许通过在功能测试中对正在运行的服务器进行HTTP调用来记录API。

供参考，这是我使用的Spock规范：

package com.example.notes

import static org.springframework.restdocs.mockmvc.MockMvcRestDocumentation.document;
import static org.springframework.restdocs.mockmvc.MockMvcRestDocumentation.documentationConfiguration;
import static org.springframework.restdocs.mockmvc.RestDocumentationRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

import grails.test.mixin.integration.Integration
import grails.transaction.*
import org.junit.Rule;
import org.springframework.beans.factory.annotation.Autowired
import org.springframework.restdocs.RestDocumentation;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.MvcResult;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext

import spock.lang.*

@Integration
@Rollback
class ApiDocumentationSpec extends Specification {

    @Rule
    public final RestDocumentation restDocumentation = new RestDocumentation("build/generated-snippets");

    @Autowired
    WebApplicationContext context

    MockMvc mockMvc

    def setup() {
        this.mockMvc = MockMvcBuilders.webAppContextSetup(this.context)
                .apply(documentationConfiguration(this.restDocumentation)).build();
    }

    def cleanup() {

    }

    void "list notes"() {
        when:
            MvcResult result = this.mockMvc.perform(get("/notes")).andReturn()
        then:
            result.andExpect(status().isOk())
                .andDo(document("notes-list-example"));
    }
}

是否可以直接在grails中使用Spring MVC Test，以及如何使用？
