'assertEquals()' called on array

Reports JUnit assertEquals() calls with arguments of an array type. Such methods compare the arrays' identities instead of the arrays' contents. Array contents should be checked with the assertArrayEquals() method.

Example:

@Test public void testSort() { int[] actual = {248, 496, 0, 56}; Arrays.sort(actual); Assert.assertEquals(new int[] {0, 56, 248, 496}, actual); }

After the quick-fix is applied:

@Test public void testSort() { int[] actual = {248, 496, 0, 56}; Arrays.sort(actual); Assert.assertArrayEquals(new int[] {0, 56, 248, 496}, actual); }
