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 |
||
| 18 | final class NullValueResolverTest extends TestCase |
||
| 19 | { |
||
| 20 | |||
| 21 | /** |
||
| 22 | * @var NullValueResolver |
||
| 23 | */ |
||
| 24 | private $valueResolver; |
||
| 25 | |||
| 26 | public function setUp() |
||
| 30 | |||
| 31 | /** |
||
| 32 | * @test |
||
| 33 | */ |
||
| 34 | public function shouldNotResolveValue() |
||
| 42 | |||
| 43 | /** |
||
| 44 | * @test |
||
| 45 | */ |
||
| 46 | public function shouldNotRevertValue() |
||

It seems like the type of the argument is not accepted by the function/method which you are calling.
In some cases, in particular if PHP’s automatic type-juggling kicks in this might be fine. In other cases, however this might be a bug.
We suggest to add an explicit type cast like in the following example:
