Question

这里发生了奇怪的事情。运行任何调用的单元测试时：

FileService fileService = FileServiceFactory.getFileService();
writeChannel = fileService.openWriteChannel(file, lock);
writeChannel.closeFinally();

我得到以下异常 - 代码在单元测试和其他工作站之外运行正常 - 所以这是我不得不使用的Windows XP笔记本电脑的环境问题。测试在我的其他个人电脑和笔记本电脑上运行正常（运行ubuntu）

您可以通过向LocalServiceTestHelper设置添加LocalBlobstoreServiceTestConfig（）来避免这种情况。在将其添加到失败的测试类之后，我才开始工作。

我不确定这确实是一个错误。我认为这个bug是在SDK提供本地blobstore仿真之前没有正确的测试设置配置。
