Spock: method not recognized as an invocation

Question

Trying to figure out why Spock doesn't seem to recognize a method call (of a Mocked object) as an invocation. Looked at the docs ( http://spockframework.org/spock/docs/1.1-rc-3/all_in_one.html#_mocking ) and couldn't figure it out.

Here's a dumbed down version of the code:

class VmExportTaskSplitter implements TaskSplitter<Export> {

    @Inject
    AssetServiceClient assetServiceClient

    @Override
    int splitAndSend(Export export) {

        Map batch = [:]
        Map tags = [:]

        if (true) {
            println('test')
            batch = assetServiceClient.getAssetIdBatch(export.containerUuid,
                    export.userUuid, (String) batch.scrollId, tags)
            print('batch: ')
            println(batch)
        }

        return 1

    }
}

And now the test:

class VmExportTaskSplitterSpecification extends Specification{
    def "tags should be parsed correctly"(){
        setup:
        Export export = new Export(containerUuid: "000", userUuid: "000", chunkSize: 10)
        AssetServiceClient client = Mock(AssetServiceClientImpl)
        VmExportTaskSplitter splitter = new VmExportTaskSplitter()
        splitter.assetServiceClient = client
        Map map1 = [assetIds:["1","2","3","4","5"],scrollId:null]
        client.getAssetIdBatch(_ as String,_ as String, null, _ as Map) >> map1

        when:
        splitter.splitAndSend(export)

        then:
        1 * client.getAssetIdBatch(_ as String, _ as String, _ as String, _ as Map)
    }
}

Here's the annoying part: both lines on either side of the assetServiceClient.getAssetIdBatch call are printed. But Spock is claiming there are no invocations whatsoever...

Using logging directory: './logs'
Using log file prefix: ''
test
batch: [assetIds:[1, 2, 3, 4, 5], scrollId:null]

Too few invocations for:

1 * client.getAssetIdBatch(_ as String, _ as String, _ as String, _ as Map)   (0 invocations)

Unmatched invocations (ordered by similarity):

None

Answer 1

Change this line:

1 * client.getAssetIdBatch(_ as String, _ as String, _ as String, _ as Map)   (0 invocations)

... on:

1 * client.getAssetIdBatch(_ as String, _ as String, _, _ as Map)

In VmExportTaskSplitter you pass empty Map into getAssetIdBatch method so batch.scrollId will be null and it will not match the _ as String .

Your specification can be also simplified, but it depends on what do you need to test. Guessing from the then part you test only if the getAssetIdBatch method was called then it is enough to write it like this:

def "tags should be parsed correctly"() {
    setup:
    Export export = new Export(containerUuid: "000", userUuid: "000", chunkSize: 10)
    AssetServiceClient client = Mock(AssetServiceClient)
    VmExportTaskSplitter splitter = new VmExportTaskSplitter()
    splitter.assetServiceClient = client

    when:
    splitter.splitAndSend(export)

    then:
    1 * client.getAssetIdBatch('000', '000', null, [:])
}
