 spring mock测试的时候，可以根据spring docs 和MockMvc应用结合起来自动生成接口api文档；

 

@RunWith(SpringRunner.class)
@SpringBootTest
public class SpringRestDocsCommTest {
    //公共参数
protected static final ParameterDescriptor REQUEST_ID = parameterWithName("id").description("数据ID，不能为空");
    protected static final ParameterDescriptor REQUEST_PAGE_NUMBER = parameterWithName("pageNum").description("页码，第一页页码为1，默认值为1");
    protected static final ParameterDescriptor REQUEST_PAGE_SIZE = parameterWithName("pageSize").description("页长，默认值为10");
    protected static final FieldDescriptor REQUEST_OPT_LOCK = fieldWithPath("optLock").type("Integer").description("数据库乐观锁,不能为空");
//公共响应
protected static final FieldDescriptor RESPONSE_OPT_LOCK = fieldWithPath("optLock").type("Integer").description("数据库乐观锁");
    protected static final FieldDescriptor RESPONSE_PAGE_NUMBER = fieldWithPath("pageNum").type("Integer").description("页码");
    protected static final FieldDescriptor RESPONSE_PAGE_SIZE = fieldWithPath("pageSize").type("Integer").description("页长");
    protected static final FieldDescriptor RESPONSE_SIZE = fieldWithPath("size").type("Integer").description("查询总数");
    protected static final FieldDescriptor RESPONSE_START_ROW = fieldWithPath("startRow").type("Integer").description("初始行数");
    protected static final FieldDescriptor RESPONSE_END_ROW = fieldWithPath("endRow").type("Integer").description("结尾行数");
    protected static final FieldDescriptor RESPONSE_TOTAL = fieldWithPath("total").type("Integer").description("总数");
    protected static final FieldDescriptor RESPONSE_PAGES = fieldWithPath("pages").type("Integer").description("总页数");
    protected static final FieldDescriptor RESPONSE_PRE_PAGE = fieldWithPath("prePage").type("Integer").description("前页页数");
    protected static final FieldDescriptor RESPONSE_NEXT_PAGE = fieldWithPath("nextPage").type("Integer").description("后页页数");
    protected static final FieldDescriptor RESPONSE_IS_FIRST_PAGE = fieldWithPath("isFirstPage").type("Boolean").description("是否是第一页");
    protected static final FieldDescriptor RESPONSE_IS_LAST_PAGE = fieldWithPath("isLastPage").type("Boolean").description("是否是最后一页");
    protected static final FieldDescriptor RESPONSE_HAS_PRE_PAGE = fieldWithPath("hasPreviousPage").type("Boolean").description("是否还有前页");
    protected static final FieldDescriptor RESPONSE_HAS_NEXT_PAGE = fieldWithPath("hasNextPage").type("Boolean").description("是否还有后页");
    protected static final FieldDescriptor RESPONSE_NAV_PAGES = fieldWithPath("navigatePages").type("Integer").description("导航页码数");
    protected static final FieldDescriptor RESPONSE_NAV_PAGE_NUMBER = fieldWithPath("navigatepageNums").type("Integer[]").description("所有导航页号");
    protected static final FieldDescriptor RESPONSE_NAV_FIRST_PAGE = fieldWithPath("navigateFirstPage").type("Integer").description("导航第一页");
    protected static final FieldDescriptor RESPONSE_NAV_LAST_PAGE = fieldWithPath("navigateLastPage").type("Integer").description("导航最后页");
    protected static final FieldDescriptor RESPONSE_LAST_PAGE = fieldWithPath("lastPage").type("Integer").description("最后页数");
    protected static final FieldDescriptor RESPONSE_FIRST_PAGE = fieldWithPath("firstPage").type("Integer").description("第一页数");
    protected static final FieldDescriptor RESPONSE_CREATE_TIME = fieldWithPath("createTime").type("Date").description("创建时间");
    protected static final FieldDescriptor RESPONSE_UPDATE_TIME = fieldWithPath("updateTime").type("Date").description("更新时间");
    private String host = "localhost";
    private int port = 8080;
    private String scheme = "http";
@Rule
public JUnitRestDocumentation restDocumentation = new JUnitRestDocumentation();
    protected MockMvc mockMvc;
@Autowired
protected ObjectMapper objectMapper;
@Autowired
private WebApplicationContext context;
@Before
public void setUp() {
        Snippet[] defaultSnippets = new Snippet[]{CliDocumentation.curlRequest(), CliDocumentation.httpieRequest(), HttpDocumentation.httpRequest(), HttpDocumentation.httpResponse(), PayloadDocumentation.requestBody(), PayloadDocumentation.responseBody(), HeaderDocumentation.requestHeaders()};
        this.mockMvc = MockMvcBuilders.webAppContextSetup(this.context)
                .apply(documentationConfiguration(this.restDocumentation)
                        .snippets().withTemplateFormat(TemplateFormats.asciidoctor()).withEncoding("UTF-8")
                        .withDefaults(defaultSnippets)
                        .and()
                        .uris().withScheme(scheme).withHost(host).withPort(port)
                        .and()
                )
                .build();
}

    @Test
public void test() {
        System.out.println("----SpringRestDocsTest:" + host + "---" + port + "---" + scheme);
}
}

 

具体的测试类生成如下：

@FixMethodOrder(MethodSorters.NAME_ASCENDING)
public class UserRestServiceTest extends SpringRestDocsCommTest {
    @Test
public void a_getUserList() throws Exception {
        MultiValueMap, String> params = new LinkedMultiValueMap<>();
params.add("pageNum", "1");
params.add("pageSize", "5");
params.add("status", "0");
        this.mockMvc.perform(get("/v1/users").params(params))
                .andExpect(status().isOk())
                .andDo(document("users-list", requestParameters(
                        REQUEST_PAGE_NUMBER,
REQUEST_PAGE_SIZE,
parameterWithName("status").description("用户状态,可以为空")),
responseFields(
                                subsectionWithPath("list").type("System对象数组").description("用户列表，具体数据参考根据ID获取用户接口"),
RESPONSE_PAGE_NUMBER,
RESPONSE_PAGE_SIZE,
RESPONSE_SIZE,
RESPONSE_START_ROW,
RESPONSE_END_ROW,
RESPONSE_TOTAL,
RESPONSE_PAGES,
RESPONSE_PRE_PAGE,
RESPONSE_NEXT_PAGE,
RESPONSE_IS_FIRST_PAGE,
RESPONSE_IS_LAST_PAGE,
RESPONSE_HAS_PRE_PAGE,
RESPONSE_HAS_NEXT_PAGE,
RESPONSE_NAV_PAGES,
RESPONSE_NAV_PAGE_NUMBER,
RESPONSE_NAV_FIRST_PAGE,
RESPONSE_NAV_LAST_PAGE/*,
                                RESPONSE_LAST_PAGE,       // 这2个参数在新版本已经被取消了
                                RESPONSE_FIRST_PAGE*/)));
}


    @Test
public void b_getUserById() throws Exception {
        this.mockMvc.perform(
                get("/v1/users/{id}", 1))
                .andExpect(status().isOk())
                .andDo(document("users-get",
pathParameters(REQUEST_ID),
responseFields(
                                subsectionWithPath("id").type("Long").description("用户ID"),
subsectionWithPath("name").type("String").description("用户姓名"),
subsectionWithPath("age").type("Integer").description("用户年龄"),
subsectionWithPath("status").type("Integer").description("用户状态"),
subsectionWithPath("description").type("String").description("描述信息"),
RESPONSE_CREATE_TIME,
RESPONSE_UPDATE_TIME,
RESPONSE_OPT_LOCK
)));
}
