在我的 Android 应用程序中,我设置了 Volley。
Robolectric.application 已初始化,所有其他测试运行顺利。尝试获取模拟的 HTTP 响应时出现此错误。
这是我的测试:
@RunWith(MyRobolectricTestRunner.class)
public class ApiTests {
@Inject
protected Api api;
@Before
public void setUp() {
ObjectGraph.create(new AndroidModule(Robolectric.application), new TestApplicationModule()).inject(this);
}
@Test
public void shouldGetErrorList() throws Exception {
Project project = new Project("test", "test", "test", DateTime.now());
addPendingProjectsErrorsResponse("response.json"); //adding response to FakeHttpLayer
api.getProjectErrors(project, new Listener<ProjectErrors>() {
@Override
public void onResponse(ProjectErrors response) {
assertNotNull(response);
}
}, new ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
throw new RuntimeException(error);
}
}
);
}
}
这是我得到的错误:
