/** | |
* <p> | |
* <b>Purpose</b>: This test checks to see if the Unit of Work functions 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, read back and compared. | |
* | |
* <p> | |
* <b>Responsibilities</b>: Check if the unit of work functions properly with complex inheritance mappings | |
* | |
* <p> | |
* <b>Features Used</b>: Inheritance Mappings, Unit Of Work | |
* | |
* <p> | |
* <b>Paths Covered</b>: Within the unit of work, different parts listed below were modified: | |
* <ul> | |
* <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 | |
