### Question:
AbstractMuxConnection extends AbstractBlobStoreConnection { public AbstractMuxConnection(BlobStore store, Transaction txn) { super(store); this.txn = txn; } AbstractMuxConnection(BlobStore store, Transaction txn); abstract BlobStore getStore(URI blobId, Map<String, String> hints); Set<BlobStore> getStores(String prefix); @Override void close(); @Override Blob getBlob(URI blobId, Map<String, String> hints); @Override Iterator<URI> listBlobIds(String filterPrefix); @Override void sync();  }### Answer:
@Test public void testAbstractMuxConnection() { assertEquals(store, con.getBlobStore()); }
