is it safe to call

assertEquals(byteArray, otherByteArray)

and receive the expected result? Or do I need to call

Arrays.equals()

instead?

You can use

array contentEquals otherArray

to compare two arrays by content and then assert that the result is true. Or you can wrap these arrays in lists and compare that lists:

assertEquals(byteArray.asList(), otherByteArray.asList())

Thank you, that's exactly the solution I was looking for!

The disadvantage of that is when it fails, you'll get a message, something like "expected true, got false".
