AssertJ asserting that List<Long> contains only long[]

Is there a way to assert that a List contains only/exactly long[] array?

Code:

 // arrange
    long[] result = {1, 2, 3, 4, 5};

    // act
    List<Long> digitPowNumbers = SumDigPower.findDigitPowNumbers(1, 6);

    // assert
    assertThat(digitPowNumbers).containsExactly(result);
}

I'm getting Cannot resolve method containsExactly(long[]). How can I do this assertion? Is there a way without just typing 1, 2, 3, 4, 5 into containsExactly ?

Solution

  • containsExactly() expects an array of the same element type as your list, which is Long, not the primitive long. Change your array type and it should work:

    Long[] result = {1L, 2L, 3L, 4L, 5L};
