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 |
||
| 9 | class xsDayTimeDurationTest extends \PHPUnit_Framework_TestCase |
||
| 10 | { |
||
| 11 | /** |
||
| 12 | * Sets up the fixture, for example, opens a network connection. |
||
| 13 | * This method is called before a test is executed. |
||
| 14 | */ |
||
| 15 | protected function setUp() |
||
| 19 | |||
| 20 | /** |
||
| 21 | * Tears down the fixture, for example, closes a network connection. |
||
| 22 | * This method is called after a test is executed. |
||
| 23 | */ |
||
| 24 | protected function tearDown() |
||
| 28 | |||
| 29 | /** |

||
| 31 | */ |
||
| 32 | View Code Duplication | public function testxsDayTimeDurationValid($input, $message) |
|
|
|
|||
| 33 | { |
||
| 34 | try { |
||
| 35 | $d = new xsDayTimeDuration($input); |
||
| 36 | $e = (string)$d; |
||
| 37 | } catch (\Exception $e) { |
||
| 38 | $this->fail($message . ' with Exception ' . $e->getMessage()); |
||
| 39 | } |
||
| 40 | } |
||
| 41 | |||
| 42 | public function testxsDayTimeDurationValidDataProvider() |
||

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.
