Spock：mocked类的方法不匹配

Question

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

    }
}

class VmExportTaskSplitterSpecification extends Specification{
    def "tags should be parsed correctly"(){
        setup:
        Export export = new Export(containerUuid: "000", userUuid: "000", chunkSize: 10)
        FilterSet filterSet = new FilterSet()
        filterSet.tag = [:]
        filterSet.tag['tag.Location'] = 'Boston'
        filterSet.tag['tag.Color'] = 'red'
        Map<String, String> expectedTags = ['tag.Location':'Boston', 'tag.Color':'red']
        ObjectMapper mapper = new ObjectMapper()
        export.filters = mapper.writeValueAsString(filterSet)

        def assetServiceClient = Mock(AssetServiceClientImpl) {
            Map map1 = [assetIds:["1","2","3","4","5"],scrollId:null]
            getAssetIdBatch(_ as String,_ as String, null, _ as Map) >> map1
            getAssetIdBatch('000', '000', null, ['tag.Location':'Boston', 'tag.Color':'red']) >> map1
            getAssetIdBatch(_, _, _, _) >> map1
        }

        VmExportTaskSplitter splitter = new VmExportTaskSplitter()
        splitter.assetServiceClient = assetServiceClient

        when:
        splitter.splitAndSend(export)

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

当运行此操作时，可以看到批处理仍被打印为null。我在设置交互时做错了什么？

Using logging directory: './logs'
Using log file prefix: ''
test
batch: null

Answer 1

你--像以前的许多人一样--遇到了斯波克的一个巨大难题：嘲笑和讽刺的结合，以及它必须发生在一条线上的事实。形成文档：

对相同方法调用的模仿和存根必须在相同的交互中发生。

在给定块中插入AssetServiceClient.getAssetidBatch以返回MAP1，然后在then块中验证模拟调用。后者隐式地指示模拟返回null而不是map1。思考

1 * assetServiceClient.getAssetIdBatch(_ as String, _ as String, _, _ as Map) // >> null

1 * assetServiceClient.getAssetIdBatch(_ as String, _ as String, _, _ as Map) >> map1

并在方法的作用域中定义map1，它将按预期工作。

您可能还希望从givid块中删除重复项。

不要担心它在then块中。在您输入when块之前，Spock会执行所有的模仿和stubbing。如果您想查看代码，请逐级查看。
