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 |
||
| 21 | final class FlashMessageTest extends BasePHPVisitorTest |
||
| 22 | { |
||
| 23 | public function testExtract() |
||
| 24 | { |
||
| 25 | $collection = $this->getSourceLocations(new FlashMessage(), Resources\Php\Symfony\FlashMessage::class); |
||
| 26 | |||
| 27 | $this->assertCount(1, $collection); |
||
| 28 | $source = $collection->first(); |
||
| 29 | $this->assertEquals('flash.created', $source->getMessage()); |
||
| 30 | } |
||
| 31 | } |
