Java 使用JUnit中的Blobstore
我正在尝试测试一些使用Blobstore API的代码,但我不知道如何将一些文件放入Blobstore。以下操作不起作用:Java 使用JUnit中的Blobstore,java,google-app-engine,Java,Google App Engine,我正在尝试测试一些使用Blobstore API的代码,但我不知道如何将一些文件放入Blobstore。以下操作不起作用: private BlobKey createBlob(String path) throws Exception { FileService fileService = FileServiceFactory.getFileService(); AppEngineFile file = fileService.createNewBlobFile("foobar
private BlobKey createBlob(String path) throws Exception {
FileService fileService = FileServiceFactory.getFileService();
AppEngineFile file = fileService.createNewBlobFile("foobar");
FileWriteChannel writeChannel = fileService.openWriteChannel(file, true);
OutputStream output = Channels.newOutputStream(writeChannel);
// copy files, guava-style
InputStream input = new FileInputStream(path);
assertNotNull(input);
ByteStreams.copy(input, output);
input.close();
// just in case...
output.flush();
output.close();
writeChannel.close();
// U NO WORK!!!
BlobKey blobKey = fileService.getBlobKey(file);
assertNotNull(blobKey);
return blobKey;
}
我的配置:
new LocalServiceTestHelper(
new LocalBlobstoreServiceTestConfig()
//.setNoStorage(true)
.setBackingStoreLocation("war/WEB-INF/appengine-generated"),
new LocalFileServiceTestConfig()
).setUp();
有什么想法吗?以下测试运行成功
public class TestBlobstore {
private static final LocalServiceTestHelper helper =
new LocalServiceTestHelper(new LocalDatastoreServiceTestConfig(),
new LocalBlobstoreServiceTestConfig()
);
public TestBlobstore() {
}
@Before
public void setUp() {
helper.setUp();
}
@Test
public void testBlobstore() throws Exception {
System.out.println(createBlob("test.txt"));
}
private BlobKey createBlob(String path) throws Exception {
FileService fileService = FileServiceFactory.getFileService();
AppEngineFile file = fileService.createNewBlobFile("foobar");
FileWriteChannel writeChannel = fileService.openWriteChannel(file, true);
OutputStream output = Channels.newOutputStream(writeChannel);
// copy files, guava-style
InputStream input = new FileInputStream(path);
assertNotNull(input);
ByteStreams.copy(input, output);
input.close();
// just in case...
output.flush();
output.close();
writeChannel.closeFinally();
// U NO WORK!!!
BlobKey blobKey = fileService.getBlobKey(file);
assertNotNull(blobKey);
return blobKey;
}
}
两项修改:
- 使用LocalBlobstoreServiceTestConfig而不是LocalFileServiceTestConfig
- writeChannel.closeFinally();而不是writeChannel.close()
希望有帮助。您正在测试BlobStore功能吗?这将是奇怪的,因为它自己的开发者应该对此进行测试。听起来像是要模拟BlobStore对象,并针对thisNope进行断言和测试。我只是想测试我的代码,但我需要Blobstore中的一些文件来完成。这只是我测试设置的一部分。你的代码在什么意义上不起作用?更好的是,发布一个其他人可以运行的简单复制案例。例如,最好查看LocalServiceTestHelper的实际实例化位置。此测试返回“com.google.apphosting.api.ApiProxy$CallNotFoundException:找不到api包'file'或调用'Create()'。你知道我错了什么或遗漏了什么吗?别担心,使用“API包未找到”下的说明就成功了。这在AppEngine 1.9.28中不再适用。有人有别的办法吗?
