### Question:
WWWBlob extends AbstractBlob { public WWWBlob(URL url, BlobStoreConnection conn, StreamManager streamManager) { super(conn, toURI(url)); this.url = url; this.streamManager = streamManager; } WWWBlob(URL url, BlobStoreConnection conn, StreamManager streamManager); @Override long getSize(); @Override InputStream openInputStream(); @Override OutputStream openOutputStream(long estimatedSize, boolean overwrite); @Override boolean exists(); @Override void delete(); @Override Blob moveTo(URI blobId, Map<String, String> hints);  }### Answer:
@Test public void testWWWBlob() { try { assertEquals(blob, con.getBlob(blobId, null)); } catch (IOException e) { fail("getBlob() failed", e); } }
