| /** |
| * <p> |
| * <b>Purpose</b>: This test checks to see if the Unit of Work commitAndResume functionality works with the Inheritance mappings |
| * |
| * <p> |
| * <b>Motivation </b>: This test was written to test a new feature: the UOW. |
| * <p> |
| * <b>Design</b>: The Complex Inheritance model is used. A Company is registered into the UOW, and then |
| * its different levels of inheritance and relationship mappings are changed and commited to |
| * to the database (using the commitAndResume method), changed again, committed again, and then read back and compared. |
| * |
| * <p> |
| * <b>Responsibilities</b>: Check if the unit of work commitAndResume functionality works properly with complex inheritance mappings |
| * |
| * <p> |
| * <b>Features Used</b>: Inheritance Mappings, Unit Of Work (commitAndResume) |
| * |
| * <p> |
| * <b>Paths Covered</b>: Within the unit of work, different parts listed below were modified: |
| * <ul> |
| * <li> <i>A vehicle removed from the company</i>, |
| * <li> <i>A vehicle changed seating capacity changed</i>, |
| * <li> <i>Bicycle added to vehicles</i>, 2L inheritance from vehicle, on same table |
| * <li> <i>Car added to vehicles</i>, 2L inheritance from vehicle, has own table |
| * <li> <i>Bus added to vehicles</i>, 2L inheritance from vehicle, has own table |
| * <li> <i>Vehicle deleted</i>, deletion with inheritance |
| * <li> <i>Company name adjusted</i>, |
| * </ul> |
