"" : metadata; } Community(Context context, TableRow row); static Community find(Context context, int id); static Community create(Community parent, Context context); static Community create(Community parent, Context context, String handle); static Community[] findAll(Context context); static Community[] findAllTop(Context context); int getID(); String getHandle(); String getMetadata(String field); void setMetadata(String field, String value); String getName(); Bitstream getLogo(); Bitstream setLogo(InputStream is); void update(); Group createAdministrators(); void removeAdministrators(); Group getAdministrators(); Collection[] getCollections(); Community[] getSubcommunities(); Community getParentCommunity(); Community[] getAllParents(); Collection createCollection(); Collection createCollection(String handle); void addCollection(Collection c); Community createSubcommunity(); Community createSubcommunity(String handle); void addSubcommunity(Community c); void removeCollection(Collection c); void removeSubcommunity(Community c); void delete(); boolean equals(Object other); int hashCode(); int getType(); boolean canEditBoolean(); void canEdit(); int countItems(); DSpaceObject getAdminObject(int action); DSpaceObject getParentObject();  }### Answer:
@Test public void testGetMetadata() { assertThat("testGetMetadata 0",c.getMetadata("name"), equalTo("")); assertThat("testGetMetadata 1",c.getMetadata("short_description"), equalTo("")); assertThat("testGetMetadata 2",c.getMetadata("introductory_text"), equalTo("")); assertThat("testGetMetadata 3",c.getMetadata("logo_bitstream_id"), equalTo("")); assertThat("testGetMetadata 4",c.getMetadata("copyright_text"), equalTo("")); assertThat("testGetMetadata 5",c.getMetadata("side_bar_text"), equalTo("")); }
