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 |
||
16 | class ReadmeTest extends \PHPUnit_Framework_TestCase |
||
17 | { |
||
18 | /** |
||
19 | * @var Tester |
||
20 | */ |
||
21 | protected $tester; |
||
22 | |||
23 | protected function setUp() |
||
27 | |||
28 | protected function tearDown() |
||
32 | |||
33 | /** |
||
34 | * Test minimal. |
||
35 | */ |
||
36 | View Code Duplication | public function testMinimal() |
|
43 | |||
44 | /** |
||
45 | * Test options. |
||
46 | */ |
||
47 | View Code Duplication | public function testMore() |
|
54 | |||
55 | /** |
||
56 | * Test docs/readme. |
||
57 | */ |
||
58 | public function testDocs() |
||

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.
