Flutter: Mockito http客户端单元测试异常
Flutter: Mockito http客户端单元测试异常
提问于 2020-04-22 14:39:34
我正在尝试学习mockito http客户端测试。所以这是我的测试：
test(
'should throw SocketException',
() async {
when(mockHttpCLient.get(any, headers: anyNamed('headers')))
.thenThrow(SocketException);
expect(
() => foursquareRepositoryImpl.getVenuesDetails(venueId),
throwsA(allOf(
isArgumentError, predicate((e) => e is FetchDataException))));
},
);如你所见，当http get方法被调用时，我想抛出SocketException：
此实现的方法：
@override
Future<VenuesDetails> getVenuesDetails(String venueId) async {
try {
var response = await client.get(
'https://api.foursquare.com/v2/venues/$venueId?client_id={{client_id}}&client_secret={{client_secret}}&v={{v}}',
headers: {'Content-Type': 'application/json; charset=utf-8'});
} on SocketException catch (e) {
throw FetchDataException('No Internet connection');
}
return null;
}但是当我运行我的测试时，我得到了这个错误：
Expected: throws (<Instance of 'ArgumentError'> and satisfies function)
Actual: <Closure: () => Future<VenuesDetails>>
Which: threw FetchDataException:<Error During Communication: No Internet connection>

只需在下面更改代码，就可以很好地工作。
...
expect(foursquareRepositoryImpl.getVenuesDetails(venueId),
throwsA(isA<FetchDataException>()));
...或
...
try{
await foursquareRepositoryImpl.getVenuesDetails(venueId);
} catch (e) {
expect(e, isA<FetchDataException>());
}
