### Question:
Bitstream extends DSpaceObject { public void setDescription(String n) { bRow.setColumn("description", n); modifiedMetadata = true; addDetails("Description"); } 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(); InputStream retrieve(); Bundle[] getBundles(); int getType(); boolean isRegisteredBitstream(); int getStoreNumber(); DSpaceObject getParentObject();  }### Answer:
@Test public void testSetDescription() { String description = "new description"; bs.setDescription(description); assertThat("testSetDescription 0", bs.getDescription(), notNullValue()); assertThat("testSetDescription 1", bs.getDescription(), not(equalTo(""))); assertThat("testSetDescription 2", bs.getDescription(), equalTo(description)); }
