Mockito模棱两可的方法调用 [英] Mockito ambiguous method call
问题描述
我正在尝试存根方法调用，例如
when(amazonDynamoDBClient.batchWriteItem(anyObject())).thenReturn(batchWriteItemResultMock);
我收到此错误
错误:(198，34)Java:对batchWriteItem的引用不明确 com.amazonaws.services.dynamodbv2.AmazonDynamoDBClient中的方法batchWriteItem(com.amazonaws.services.dynamodbv2.model.BatchWriteItemRequest)和com.amazonaws.services.dynamodbv2.AmazonDynamoDBClient中的方法batchWriteItem(java.util.Map>) >
我看不出它是如何模棱两可的-方法签名是不同的，即
public BatchWriteItemResult batchWriteItem(BatchWriteItemRequest request) {
和
public BatchWriteItemResult batchWriteItem(Map<String, List<WriteRequest>> requestItems) {
我在做什么错了?
您有两个具有相同名称和返回类型的方法，每个方法都有一个参数.因此anyObject()匹配它们两者.这就是为什么您收到batchWriteItem is ambiguous消息的原因.
您可以使用Mockito.any(Class<T> type)和Mockito.anyMapOf(Class<K> keyClazz, Class<V> valueClazz)进行区分.
供参考的文档: 解决方案
You have two methods with the same name and return type, each with one parameter. So anyObject() matches both of them. That's why you get the batchWriteItem is ambiguous message.
You could use Mockito.any(Class<T> type) and Mockito.anyMapOf(Class<K> keyClazz, Class<V> valueClazz) to distinguish between them.
Docs for reference: any, anyMapOf
