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 |
||
| 12 | class AccesibilityContext extends BaseContext |
||
| 13 | { |
||
| 14 | /** |
||
| 15 | * @Then all images should have an alt attribute |
||
| 16 | */ |
||
| 17 | View Code Duplication | public function allImagesShouldHaveAnAltAttribute() |
|
| 24 | |||
| 25 | /** |
||
| 26 | * @Then the title should not be longer than :arg1 |
||
| 27 | */ |
||
| 28 | public function theTitleShouldNotBeLongerThan($arg1) |
||
| 35 | |||
| 36 | /** |
||
| 37 | * @Then all tables should have a table header |
||
| 38 | */ |
||
| 39 | View Code Duplication | public function allTablesShouldHaveATableHeader() |
|
| 46 | |||
| 47 | /** |
||
| 48 | * @Then all tables should have at least one data row |
||
| 49 | */ |
||
| 50 | View Code Duplication | public function allTablesShouldHaveAtLeastOneDataRow() |
|
| 57 | } |
||
| 58 |
Duplicated code is one of the most pungent code smells. If you need to duplicate the same code in three or more different places, we strongly encourage you to look into extracting the code into a single class or operation.
