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);
  }
