Question

我知道这个问题之前必须要问过一千次，但Stackoverflow的答案都不适合我。我正在尝试为使用基本身份验证的restful api创建一个单元测试。以下是API的代码：

@GET
@Timed
@Path("/getAuthPerson/{id}")
@Produces(MediaType.APPLICATION_JSON)
public Person getAuthPerson(@PathParam("id")int id, @Auth Person user) {

    /* use HTTP header:
    Authorization : Basic dGVzdDpzZWNyZXQ=

    For negative test case, use
    Authorization : Basic dGVzdDoxMjM=
     */

    if(user.getName().isEmpty()) {
        return null;
    }

    Person p = new Person();
    p.setName("Test");
    p.setId(0);
    p.setAge(10);

    return p;
}

当我调用浏览器的RESTful客户端，我的IDE或来自Fiddler时，这个API有效，即当我没有提供auth标头/不正确的标头时我正确得到401，并且当我提供正确的时候能够取回资源头。但是，单元测试api拒绝工作，这里是单元测试的代码：

public class PersonResourceTest {
private static final PersonDao personDao = mock(PersonDao.class);

@ClassRule
public static final ResourceTestRule resources = ResourceTestRule.builder()
        .addResource(new PersonResource(personDao))
        .build();

private static Person getDummyPerson() {
    Person person = new Person();
    person.setName("John Doe");
    person.setBirthDateTime(new DateTime("2012-11-21T13:01:33.568Z"));
    person.setAge(10);
    return person;
}

private final Person person = getDummyPerson();

@Before
public void setup() {
    when(personDao.getPerson(eq(123))).thenReturn(person);
    // we have to reset the mock after each test because of the
    // @ClassRule, or use a @Rule as mentioned below.
    reset(personDao);
}

@Test
public void authenticatedTestGetPositive() {
    PersonDao testDao = mock(PersonDaoMongoImpl.class);
    testDao.createPerson(person);

    WebResource.Builder builder = resources.client().resource("/persons/getAuthPerson/123").getRequestBuilder();
    builder.header("Authorization", "Basic dGVzdDpzZWNyZXQ=");
    //builder.header("Authorization", "Basic dGVzdDoxMjM=");
    builder.accept(MediaType.APPLICATION_JSON);

    Person p = builder.get(Person.class);
    assertThat(p).isEqualTo(person);
    verify(testDao).getPerson(123);
}

}

不涉及身份验证的单元测试工作正常，但是此身份验证单元测试会出现此错误：

    ERROR [2014-08-10 14:48:58,108] com.sun.jersey.spi.container.ContainerRequest: A message body reader for Java class com.rms.pilotapi.core.Person, and Java type class com.rms.pilotapi.core.Person, and MIME media type application/octet-stream was not found.

您需要在JUnit testrule（PersonAuthenticator）中注册@ClassRule（或您用于身份验证器的名称）。

问题是Jersey试图反序列化您的参数@Auth Person user，该参数应该由您的身份验证器处理。
