			0 ignored issues – show Bug introduced 2017-01-03 10:13 UTC by Report Bug Copy Issue Report It seems like `$doctrineCache` defined by `$this->createMock(\Roave...tiPuttableCache::class)` on line `25` can also be of type `object<PHPUnit_Framework_MockObject_MockObject>`; however, `Roave\DoctrineSimpleCach...eAdapter::__construct()` does only seem to accept `object<Doctrine\Common\Cache\Cache>`, maybe add an additional type check? If a method or function can return multiple different values and unless you are sure that you only can receive a single value in this context, we recommend to add an additional type check: /** * @return array\|string */ function returnsDifferentValues($x) { if ($x) { return 'foo'; } return array(); } $x = returnsDifferentValues($y); if (is_array($x)) { // $x is an array. } If this a common case that PHP Analyzer should handle natively, please let us know by opening an issue.
