Question

我正在尝试为资源设置测试：

@Override
protected void setUpResources() throws Exception {
    when(ratingDao.getRating("karan")).thenReturn(rating);
    addResource(new RatingResource(ratingDao));
}

@Test
public void testRatingsGetsTracks() throws Exception{
    assertThat(client().resource("/ratings").queryParam("username", "karan").get(Rating.class)).isEqualTo(rating);
    verify(ratingDao).getRating("karan");
}

但是，我得到了204：

1 > GET /ratings?username=karan
1 >

我不知道为什么。我测试过Rating可以序列化为json。

以下是资源的实施：

@Path("/ratings")
@Produces(MediaType.APPLICATION_JSON)
public class RatingResource {
    private RatingDAO ratingDao;

    public RatingResource(RatingDAO ratingDao) {
        this.ratingDao = ratingDao;
    }

    @GET
    @Timed
    public Rating getRating(@QueryParam("username") String username)  {
        return ratingDao.getRating(username);
    }
}

Answer 1

@Override
protected void setUpResources() throws Exception {
    when(ratingDao.getRating("karan")).thenReturn(rating);
    addResource(new RatingResource(ratingDao));
}

由于某种原因，没有设置ratingDao mock。当我将该行移动到setUp方法时，这是有效的。

Dropwizard / Jersey为资源返回204
