### Question:
Bitstream extends DSpaceObject { public void setFormat(BitstreamFormat f) throws SQLException { if (f == null) { bitstreamFormat = BitstreamFormat.findUnknown(bContext); } else { bitstreamFormat = f; } bRow.setColumnNull("user_format_description"); bRow.setColumn("bitstream_format_id", bitstreamFormat.getID()); modified = true; } 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 testSetFormat() throws SQLException { int id = 3; BitstreamFormat format = BitstreamFormat.find(context, id); bs.setFormat(format); assertThat("testSetFormat 0", bs.getFormat(), notNullValue()); assertThat("testSetFormat 1", bs.getFormat(), equalTo(BitstreamFormat.find(context, id))); }
