Using Blobstore from JUnit

Question

I am trying to test some code that uses the Blobstore API, but I really don't understand how I should get some files in blobstore. The following does not work:

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; } 

My configuration:

 new LocalServiceTestHelper( new LocalBlobstoreServiceTestConfig() //.setNoStorage(true) .setBackingStoreLocation("war/WEB-INF/appengine-generated"), new LocalFileServiceTestConfig() ).setUp(); 

Any ideas?

Next Test Run Passed

 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; } } 

Two modifications:

• User LocalBlobstoreServiceTestConfig instead of LocalFileServiceTestConfig
• writeChannel.closeFinally (); instead of writeChannel.close ()

I hope for this help.
