### Question:
Bitstream extends DSpaceObject { public boolean isRegisteredBitstream() { return BitstreamStorageManager .isRegisteredBitstream(bRow.getStringColumn("internal_id")); } Bitstream(Context context, TableRow row); static Bitstream find(Context context, int id); static Bitstream[] findAll(Context context); int getID(); String getHandle(); int getSequenceID(); void setSequenceID(int sid); String getName(); void setName(String n); String getSource(); void setSource(String n); String getDescription(); void setDescription(String n); String getChecksum(); String getChecksumAlgorithm(); long getSize(); void setUserFormatDescription(String desc); String getUserFormatDescription(); String getFormatDescription(); BitstreamFormat getFormat(); void setFormat(BitstreamFormat f); void update(); boolean isDeleted(); InputStream retrieve(); Bundle[] getBundles(); int getType(); boolean isRegisteredBitstream(); int getStoreNumber(); DSpaceObject getParentObject(); String get_internal_id();  }### Answer:
@Test public void testIsRegisteredBitstream() { assertThat("testIsRegisteredBitstream 0", bs.isRegisteredBitstream(), equalTo(false)); }
