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,我得到一个 204:
1 > GET /ratings?username=karan
1 >

我不知道为什么。我已经测试过Rating
可以将 a 序列化为 json。
下面是资源的实现:
@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);
}
}
