| /** |
| * <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>: implement an equals method for objects that always returns true, and in another object |
| * implement an equals that always returns false. Now check the four paths mentioned below by |
| * registering the two objects into the UOW, compare the clones returned. If the two objects are |
| * different (regardless of what they think) then different clones must be returned. |
| * |
| * <p> |
| * <b>Responsibilities</b>: Verify that the registration of the objects does not depend on the equals method |
| * <p> |
| * <b>Features Used</b>: Unit Of Work, Registering feature |
| * <p> |
| * <b>Paths Covered</b>: Within the unit of work, different parts of the employee were set with clones: |
| * <ul> |
| * <li> <i>Think they are equal but are unequal, clones are different</i> |
| * <li> <i>Think they are equal and are equal, clones are identical</i> |
| * <li> <i>Think they are unequal but are equal, clones are identical</i> |
| * <li> <i>Think they are unequal and are unequal, clones are different</i> |
| * </ul> |
