要接受模拟
- 用于距离矩阵的Google Geo API（外部API调用）
...
...
/**
* The API is very expensive to be built
*/
private GeoApiContext geoApi;
// Inside of a Google Guave Cache load method...
// The calculation from Google
DistanceMatrix calculationResult;
DistanceMatrixApiRequest req = DistanceMatrixApi.newRequest(geoApi);
calculationResult = req.origins(addresses.getOriginAddress())
.destinations(addresses.getDestinationAddress())
.mode(TravelMode.DRIVING)
.avoid(RouteRestriction.TOLLS)
.language(properties.getLanguage())
.await();
带有Mokito和Powermock的测试类
- 然后测试类失败...
DistanceMatrixService是调用的位置... - 试图在Mokito 3中实现类似于How can I mock Google's Geocoding API request using mockito/powermock? 的功能

具有故障详细信息的Stacktrace
- 测试失败，并显示NullPointerException ...
-
distancematrix.DistanceMatrixServiceTests.testGetDistanceMatrixForAddresses(DistanceMatrixServiceTests.java:87)恰好是await()方法调用...但是它已被when嘲笑when(distanceMatrixRequest.await()).thenReturn(distanceMatrixResult);

问题
- ExtendsWith是否正确？为什么模拟为null？
- 我还要使用其他东西吗？
