Question

编辑：如果我删除了spring-restdoc代码，那么测试将通过maven传递。

我试图在Spring Boot网络应用程序中使用MockMVC编写集成测试。

我现在只有一个测试（下面的步骤和代码），如果我在IDE中运行它，但是如果由Maven执行则会失败并返回以下堆栈跟踪：

        at org.springframework.test.web.servlet.MockMvc$1.andDo(MockMvc.java:158)

代码：

我添加了starter-test依赖项，并为将来的所有测试创建了一个超类：

@Ignore
@MappedSuperclass
@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = Application.class)
@WebAppConfiguration
@ActiveProfiles(value = {"test"})
public class IntegrationTest
{
    @Autowired
    WebApplicationContext context;

    MockMvc mockMvc;

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

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

然后我创建了这个测试：

public class PostsTest extends IntegrationTest
{
    @Test
    public void getAll() throws Exception
    {
        mockMvc.perform(get("/api/v1/posts").accept(MediaType.APPLICATION_JSON_VALUE)
            .andExpect(status().isOk())
            .andDo(document("posts-index", preprocessResponse(prettyPrint()), responseFields(
                fieldWithPath("data").description("The response payload"),
                fieldWithPath("data.[].id").description("ID"),
                fieldWithPath("data.[].title").description("Title"),
                fieldWithPath("data.[].body").description("Content"),
                fieldWithPath("data.[].type").description("Type"),
                fieldWithPath("data.[].createdAt").description("Creation date"),
                fieldWithPath("data.[].modifiedAt").description("Last edit date"),
                fieldWithPath("data.[].entityType").description("Entity type"),
                fieldWithPath("meta").description("The response metadata")
            )));
    }
}

Answer 1

我发现从restdocs代码中删除了preprocessResponse(prettyPrint())，测试通过了。

编辑：正如Andy Wilkinson在评论中所报道的那样，此错误已通过1.0.2.BUILD-SNAPSHOT的版本spring-restdocs修复。

Answer 2

你正在解析json，我怀疑它是从文件中读取的。

该文件似乎以错误的编码保存，例如ISO-8859-1。确保它以UTF-8，UTF-16或UTF-32保存。大多数JSON解析器都会猜测前四个字节的编码，如果找到不受支持的编码，则会失败。

JsonParseException：MockMVC和Maven的UTF-8中间字节0x20无效
