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 MetaTagTest extends TestCase |
||
14 | { |
||
15 | View Code Duplication | public function testRenderName() |
|
28 | |||
29 | View Code Duplication | public function testRenderProperty() |
|
42 | |||
43 | View Code Duplication | public function testRenderHttpEquiv() |
|
56 | |||
57 | public function testRenderNothing() |
||

67 | /** |

68 | * @expectedException \InvalidArgumentException |
||
69 | * @expectedExceptionMessage Meta tag of type "unknownType" doesn't exist. Existing types are: name, property and http-equiv. |

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.
