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 |
||
8 | class ParameterTest extends TestCase |
||
9 | { |
||
10 | |||
11 | /** |
||
12 | * @var Parameter |
||
13 | */ |
||
14 | private $parameter; |
||
15 | |||
16 | protected function setUp() |
||
20 | |||
21 | protected function tearDown() |
||
25 | |||
26 | public function testGetKeyName() |
||
30 | |||
31 | View Code Duplication | public function testSetGetValue() |
|
40 | |||
41 | public function testArrayValue() |
||
55 | |||
56 | View Code Duplication | public function testShouldSkipConvertion() |
|

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.
