			0 ignored issues – show Documentation Bug introduced 2019-04-03 09:15 UTC by Report Bug Copy Issue Report It seems like `$this->getMockBuilder('P...rInterface')->getMock()` of type `object<PHPUnit\Framework\MockObject\MockObject>` is incompatible with the declared type `object<Pagerfanta\Adapter\AdapterInterface>` of property `$adapter`. Our type inference engine has found an assignment to a property that is incompatible with the declared type of that property. Either this assignment is in error or the assigned type should be added to the documentation/type hint for that property.. Loading history...
