assertk-org/assertk v0.20

on GitHub

Added

• Add corresponds/doesNotCorrespond to compare values with a correspondence function. This is
  useful when the value doesn't implement equals.

Changed

• Changed the signature of isEqualTo from Any? to T. This should not effect any existing code
  due to T being covariant. The one improvement this brings is that literal numbers can be inferred
  to the correct type. Before this change assertThat(1L).isEqualTo(1) would fail, now it passes.

Fixed

• Fixed isSuccess failing on null return values
