英文:
No suitable method found for thenReturn
问题
KinesisAsyncClient kinesisClient = mock(KinesisAsyncClient.class);
PutRecordResponse result = PutRecordResponse.builder().shardId("shard-12345").build();
when(kinesisClient.putRecord(any()))
.thenReturn(CompletableFuture.completedFuture(result));
英文:
I am new to java and mockito, trying to mock my
//kinesisClient is of type KinesisAsyncClient
PutRecordResponse result = kinesisClient.putRecord(putRecordRequest).get();
like below:
KinesisAsyncClient kinesisClient = mock(KinesisAsyncClient.class);
PutRecordResult res = mock(PutRecordResult.class);
res.setShardId("shard-12345");
when(kinesisClient.putRecord(any()).get())
.thenReturn(res);
it's giving
error: no suitable method found for thenReturn(PutRecordResult)
.thenReturn(res);
I tried
KinesisAsyncClient kinesisClient = mock(KinesisAsyncClient.class);
final PutRecordResult res = new PutRecordResult();
res.setShardId("shard-12345");
when(kinesisClient.putRecord(any()).get())
.thenReturn(res);
but same error. I am not sure what I am doing wrong here. Can anyone help me on this?

The reason for this error is that the thenReturn method expects a PutRecordResponse object, but you are passing in a PutRecordResult object.
To fix this error, you should create a PutRecordResponse object and set its sequenceNumber and shardId fields to appropriate values, then use it in the thenReturn method like this:
KinesisAsyncClient kinesisClient = mock(KinesisAsyncClient.class);
PutRecordResponse res = mock(PutRecordResponse.class);
when(res.getSequenceNumber()).thenReturn("12345");
when(res.getShardId()).thenReturn("shard-12345");
when(kinesisClient.putRecord(any())).thenReturn(res);
// Call the method that uses the mocked KinesisAsyncClient
Here, we are mocking the PutRecordResponse object and setting its sequenceNumber and shardId fields to appropriate values. Then, we are using the thenReturn method to return a CompletableFuture that completes with the mocked PutRecordResponse object when the putRecord method is called on the mocked KinesisAsyncClient.
