Unit testing asserts can be difficult to use. Approval tests simplify this by taking a snapshot of the results, and confirming that they have not changed.

Interesting approach to testing using Combination Approvals:

@Test
public void upateQuality() throws Exception {
    CombinationApprovals.verifyAllCombinations(
        this::doUpdateQuality,
        new String []{"foo", "bar", "baz"},
        new Integer []{-1, 0, 11},
        new Integer[0, 1, 49, 50});    
}

private String doUpdateQuality(String name, int sellIn, int quality) { /*...*/ }
