我想测试一种使用Unirest将获取请求发送到服务器的方法
我已经使用PowerMockito和Mockito测试了一些方法,但是当我尝试在下面的方法中进行测试时,我得到了空指针异常。
这是我要测试的方法:
public HttpResponse<JsonNode> jsonRequest(String path) {
HttpResponse<JsonNode> jsonResponse = null;
try {
jsonResponse = Unirest
.get(path)
.header("accept", "application/json")
.asJson();
} catch (UnirestException e) {
System.out.println("Server is unreachable at the moment. Please try again later");
}
return jsonResponse;
}
这是测试用例:
@RunWith(PowerMockRunner.class)
@PrepareForTest(Unirest.class)
public class TestModel {
@Mock
private GetRequest getRequest;
@Mock
private HttpResponse<JsonNode> httpResponse;
@InjectMocks
DatabaseModel databaseModel;
@Test
public void testController() {
PowerMockito.mockStatic(Unirest.class);
JsonNode jsonNode = mock(JsonNode.class);
when(Unirest.get("12345")).thenReturn(getRequest);
when(getRequest.asJson()).thenReturn(httpResponse);
when(httpResponse.getStatus()).thenReturn(200);
assertEquals(200, databaseModel.jsonRequest("12345").getStatus());
}
所以我希望得到200(或者我将决定的任何身份\个人) 但是由于某种原因,我得到了java.lang.NullPointerException 将我引导至此行:
.asJson();
在getRequest中。
预先感谢
答案 0 :(得分:0)
您快到了,您忘了设置标题了:
when(Unirest.get("12345")).thenReturn(getRequest);
when(getRequest.header("accept", "application/json").thenReturn(getRequest)
when(getRequest.asJson()).thenReturn(httpResponse);
when(httpResponse.getStatus()).thenReturn(200);
