### Question:
LockManager { public boolean get(String lockName, String transactionId) { GregorianCalendar cal = new GregorianCalendar(); cal.add(Calendar.SECOND, config.getInt("lock.wait")); Date ldDate = cal.getTime(); while (new Date().before(ldDate)) { if (getInternal(lockName, transactionId)) { log.debug("Acquired lock " + lockName); return true; } else try { Thread.sleep(1000); } catch (InterruptedException e) { } } log.warn("Unable to get lock " + lockName); return false; }  @SuppressWarnings("unchecked") List<String> getAllTransactions(); boolean get(String lockName, String transactionId); void release(String lockName, String transactionId); void setGenericDao(GenericDAO genericDao); void setConfig(ContextProperties config);  }### Answer:
@Test public void testGet() { Assert.assertTrue(manager.get("test", "t1")); Assert.assertTrue(manager.get("test", "t1")); Assert.assertFalse(manager.get("test", "t2")); try { Thread.sleep(3000); } catch (InterruptedException e) { } Assert.assertTrue(manager.get("test", "t2")); manager.release("test", "t2"); Generic lock = dao.findByAlternateKey("lock", "test-" + config.getProperty("id"), null, Tenant.DEFAULT_ID); Assert.assertNotNull(lock); Assert.assertNull(lock.getString1()); Assert.assertNull(lock.getDate1()); }
