The property $tax is declared protected in Lenius\Basket\Item. Since you implement __set, consider adding a @property or @property-write.

It seems like 25 of type integer is incompatible with the declared type Lenius\Basket\Tax of property $tax.

        $this->assertEquals(25, $this->item->tax());
