Mocking with amazon s3

[thaibt]

Implementation try { var s3Object: S3Object = s3Client.getObject(getObjectRequest) s3Object.use { s3Object -> s3Object.getObjectContent().use { objectContent -> BufferedInputStream(objectContent).use { bufferedInputStreams -> bytes = bufferedInputStreams.readAllBytes() } } } } catch (e: IOException) { throw InternalException(e.message, e) } catch (e: IllegalArgumentException) { val message = "Invalid input" throw InternalException(message, e)}

Test Code @Test funget object no errors() { val s3Object = S3Object() s3Object.setObjectContent(ByteArrayInputStream("text".toByteArray())) s3 = mock<AmazonS3> { on { getObject(any(GetObjectRequest::class.java)) } doReturn s3Object } val byteBuffer: ByteArray? = s3ClientWrapper.getObject(S3_KEY) assertNotNull(byteBuffer) }

I am trying to mock with the S3AmazonClient but I am encountering a weird issue. My code for testing putObject in the native AmazonS3 code base tested just fine, but for this one - the mock gets intercept but it is not returning what I need it to? Am I missing something or is this a bug? It just jumps to the end of the implementation and the object that was supposed to get set bytes is still null from the initialization

Hmm,

So the issue seems to be the the fact that I overwrite the s3 mock and it's being overwritten but the wrapper is not picking up the new when cause that I added

on { getObject(any(GetObjectRequest::class.java)) } doReturn s3Object

Am I missing an idea where I can extend that same S3 instead of instantiating the mock again? So I dont have to do

s3ClientWrapper = S3ClientWrapper(s3, BUCKET_NAME)
