Hi,

• actual and expected are swapped
• no random tests

cheers

If there're only 3 possible colors, then color should be an enum. If you really want it to be String, then tests must ensure that solutions like this do not pass.

All the preloaded tests-related stuff should be moved to the fixture.

The reference solution must be private.

The category variable will be null for all Item instances. Please use setCategory(..) to set the appropriate Category

What is this supposed to mean? My solution doesn't do that and it passes all the tests without any problems.

class Item {Integer categoryID; Category category; ...}

Having both category and its index in the enum at once is nonsensical design.
