我在这里得到了演示者中的代码示例。我如何在改造调用中为 onSuccess 和 onFailure 编写测试
public void getNotifications(final List<HashMap<String,Object>> notifications){
if (!"".equalsIgnoreCase(userDB.getValueFromSqlite("email",1))) {
UserNotifications userNotifications =
new UserNotifications(userDB.getValueFromSqlite("email",1),Integer.parseInt(userDB.getValueFromSqlite("userId",1).trim()));
Call call = apiInterface.getNotifications(userNotifications);
call.enqueue(new Callback() {
@Override
public void onResponse(Call call, Response response) {
UserNotifications userNotifications1 = (UserNotifications) response.body();
if(userNotifications1.getNotifications().isEmpty()){
view.setListToAdapter(notifications);
onFailure(call,new Throwable());
}
else {
for (UserNotifications.Datum datum:userNotifications1.getNotifications()) {
HashMap<String,Object> singleNotification= new HashMap<>();
singleNotification.put("notification",datum.getNotification());
singleNotification.put("date",datum.getDate());
notifications.add(singleNotification);
}
view.setListToAdapter(notifications);
}
}
@Override
public void onFailure(Call call, Throwable t) {
call.cancel();
}
});
}
}
}
我如何编写单元测试来覆盖这段代码的所有情况。
谢谢
最佳答案
当您想测试来自服务 (API) 的不同响应时,最好模拟它并返回您需要的内容。
@Test
public void testApiResponse() {
ApiInterface mockedApiInterface = Mockito.mock(ApiInterface.class);
Call<UserNotifications> mockedCall = Mockito.mock(Call.class);
Mockito.when(mockedApiInterface.getNotifications()).thenReturn(mockedCall);
Mockito.doAnswer(new Answer() {
@Override
public Void answer(InvocationOnMock invocation) throws Throwable {
Callback<UserNotifications> callback = invocation.getArgumentAt(0, Callback.class);
callback.onResponse(mockedCall, Response.success(new UserNotifications()));
// or callback.onResponse(mockedCall, Response.error(404. ...);
// or callback.onFailure(mockedCall, new IOException());
return null;
}
}).when(mockedCall).enqueue(any(Callback.class));
// inject mocked ApiInterface to your presenter
// and then mock view and verify calls (and eventually use ArgumentCaptor to access call parameters)
}
关于android - Retrofit 中的单元测试以进行回调,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/45160055/
