| /** |
| * <p> |
| * <b>Purpose</b>: This test checks if UOW merge is perfromed properly. |
| * <p> |
| * <b>Motivation </b>: This test was written to fix a bug. While in a unit of work, a new |
| * object that refrenced clones, after the merge still refrenced clones. |
| * <p> |
| * <b>Design</b>: A unit of work is acquired, an employee is read in and registered to the UOW. The |
| * returned clone is stored. A new employee is created, parts of the new employee are initialized |
| * with parts of the clone. A commit is issued. After the commit is done, the merge should |
| * have replaced the clones in the new employee with the original objects that were cloned. |
| * This is verified. |
| * <p> |
| * <b>Responsibilities</b>: Verify that the merge works properly. Make sure that the original objects |
| * are pointed to by the new employee. |
| * <p> |
| * <b>Features Used</b>: Unit Of Work, Merge feature |
| * <p> |
| * <b>Paths Covered</b>: Within the unit of work, different parts of the employee were set with clones: |
| * <ul> |
| * <li> <i>Address</i> 1:1 Mapping |
| * <li> <i>Period</i> Simple Aggregate |
| * <li> <i>NormalHours</i> |
| * </ul> |
