AssertJ multidimensional arrays assertion (deep equals)

Question

Is there any option in AssertJ to make deep assertion of 2-d (N-d) arrays? Pretty much the same as java.util.Arrays#deepEquals() does but with assertion exception and prettified fail message like "element arr1[i][j] expected to be X, but was Y"

Here i found only 1d arrays assertions:

Unfortunately, there is no such feature in AssertJ but contributions are welcome. I voted for Kevin Welker suggestion.

I don't see one, but you could write your own with: AbstractAssert, or using a Comparator and the usingComparator method

There is a isDeepEqualTo() method available since 3.17.0. Check out Array2DAssertionsExamples
