下面是我试图模拟的代码,
this.dynamoDb.getTable(PropertyUtil.get(Constants.SOME_TABLE_NAME))
.putItem(
new PutItemSpec()
.withItem(new Item().withString("ID", pId).withString("eId", pEId)
.withString("activeInd", pActiveInd)));
我试过的是下面的,
mockStatic(AmazonDynamoDBClientBuilder.class);
when(AmazonDynamoDBClientBuilder.defaultClient()).thenReturn(Mockito.mock(AmazonDynamoDB.class));
PowerMockito.mockStatic(PropertyUtil.class);
when(PropertyUtil.get(Constants.Some__ID_MAPPING_TABLE_NAME)).thenReturn("SOME_TABLE_NAME");
Table vTable = mock(Table.class);
PutItemSpec vPutItemSpec = mock(PutItemSpec.class);
PutItemResult vPutItemResult = new PutItemResult();
PowerMockito.whenNew(PutItemSpec.class).withAnyArguments().thenReturn(vPutItemSpec);
PowerMockito.when(vTable.putItem(vPutItemSpec)).thenReturn(vPutItemOutcome);
我得到的错误在于,
java.lang.IllegalArgumentException: null
at com.amazonaws.services.dynamodbv2.document.PutItemOutcome.<init>(PutItemOutcome.java:33) ~[aws-java-sdk-dynamodb-1.11.400.jar:?]

请提出建议,我需要修复,我是Mock和JUnit的新手。提前致谢。
使用DynamoDBMapper可以让您的生活更轻松。它是从AWS映射SDK的对象。这意味着您要在代码中创建要处理的Plain Old Java对象,只需向类添加注释,然后将对象映射到DynamoDB。
好处是更清晰的代码,以及使您的对象琐碎模拟。
在您的情况下,此代码:
this.dynamoDb.getTable(PropertyUtil.get(Constants.SOME_TABLE_NAME))
.putItem(
new PutItemSpec()
.withItem(new Item().withString("ID", pId).withString("eId", pEId)
.withString("activeInd", pActiveInd)));
会成为:
SOME_TABLE_NAME thing = new SOME_TABLE_NAME().id(pId).eId(pEid).activeInd(pActiveInd);
Mapper.save(thing);
或类似的。如你所见,更清洁。
this.dynamoDb
.getTable(PropertyUtil.get(Constants.SOME_TABLE_NAME))
.putItem(new PutItemSpec()
.withItem(new Item().withString("ID", pId).withString("eId", pEId)
.withString("activeInd", pActiveInd)));
为什么你不这样做。
AmazonDynamoDB dynamoDb = Mockito.mock(AmazonDynamoDB.class);
Table mockTable = Mockito.mock(Table.class)
PutItemOutcome itemOutcome = Mockito.mock(PutItemOutcome.class)
Mockito.when(mockTable.putItem(Mockito.any(PutItemSpec.class)).thenReturn(itemOutcome);
Mockito.when(dynamoDb.getTable(Mockito.any(Property.class)).thenReturn(mockTable);
我认为你不需要手工模拟PutItemSpec。另一种选择就是使用
Mockito.when(mockTable.putItem(Mockito.any(PutItemSpec.class)). thenCallRealMethod();
