Duplicate code is one of the most pungent code smells. A rule that is often used is to re-structure code once it is duplicated in three or more places.
Common duplication problems, and corresponding solutions are:
| 1 | <?php |
||
| 13 | class ClientTest extends AbstractTest |

We suggest to add an explicit type cast like in the following example:
