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 namespace Modules\Setting\Tests;  | 
            ||
| 3 | class SettingsTest extends BaseSettingTest  | 
            ||
| 4 | { | 
            ||
| 5 | /**  | 
            ||
| 6 | * @var \Modules\Setting\Support\Settings  | 
            ||
| 7 | */  | 
            ||
| 8 | protected $setting;  | 
            ||
| 9 | |||
| 10 | public function setUp()  | 
            ||
| 15 | |||
| 16 | /** @test */  | 
            ||
| 17 | View Code Duplication | public function it_gets_a_setting_without_locale()  | 
            |
| 36 | |||
| 37 | /** @test */  | 
            ||
| 38 | View Code Duplication | public function it_gets_setting_in_given_locale()  | 
            |
| 57 | |||
| 58 | /** @test */  | 
            ||
| 59 | public function it_returns_a_default_value_if_no_setting_found()  | 
            ||
| 67 | }  | 
            ||
