### Question:
Bundle extends DSpaceObject { public Bitstream getBitstreamByName(String name) { Bitstream target = null; Iterator i = bitstreams.iterator(); while (i.hasNext()) { Bitstream b = (Bitstream) i.next(); if (name.equals(b.getName())) { target = b; break; } } return target; } Bundle(Context context, TableRow row); static Bundle find(Context context, int id); int getID(); String getName(); void setName(String name); int getPrimaryBitstreamID(); void setPrimaryBitstreamID(int bitstreamID); void unsetPrimaryBitstreamID(); String getHandle(); Bitstream getBitstreamByName(String name); Bitstream[] getBitstreams(); Item[] getItems(); Bitstream createBitstream(InputStream is); Bitstream registerBitstream(int assetstore, String bitstreamPath); void addBitstream(Bitstream b); void setOrder(int bitstreamIds[]); void removeBitstream(Bitstream b); void update(); int getType(); void inheritCollectionDefaultPolicies(Collection c); void replaceAllBitstreamPolicies(List<ResourcePolicy> newpolicies); List<ResourcePolicy> getBundlePolicies(); List<ResourcePolicy> getBitstreamPolicies(); DSpaceObject getAdminObject(int action); DSpaceObject getParentObject();  }### Answer:
@Test public void testGetBitstreamByName() throws FileNotFoundException, SQLException, IOException, AuthorizeException { new NonStrictExpectations() { AuthorizeManager authManager; { AuthorizeManager.authorizeAction((Context) any, (Bundle) any, Constants.ADD); result = null; } }; String name = "name"; assertThat("testGetHandle 0", b.getBitstreamByName(name), nullValue()); File f = new File(testProps.get("test.bitstream").toString()); Bitstream bs = Bitstream.create(context, new FileInputStream(f)); bs.setName(name); b.addBitstream(bs); assertThat("testGetHandle 1", b.getBitstreamByName(name), notNullValue()); assertThat("testGetHandle 2", b.getBitstreamByName(name), equalTo(bs)); assertThat("testGetHandle 3", b.getBitstreamByName(name).getName(), equalTo(name)); context.commit(); }
